  • Visiting Astronomers Travel Guide [1]
  • NOAO-S Facilities Manual (pdf) [2]
  • NOAO proposal information [3]
  • Director's discretionary time [4]
  • General travel and tourism in Chile [5]
  • Basic Integral Security Guide for Visitors and Foreign Residents in Chile [6] (PDF, from ONEMI – The National Emergency Bureau)
  • Meet our staff at science tea in the La Serena office library, Fridays @11am, except on days where we have a colloquium scheduled.
  • You will not be able to connect to the CTIO internet until you have have registered the equipment's MAC address here. [7]  Please check our Visitor's Computer Guidelines [8].

For OUR Information:

  • Once you have arranged your trip, please let us know your Travel Plans [9].
  • Please tell us the instrument setup [10] you need by filling in the visitor support questionaire.
  • Please consider giving a talk [11] -- CTIO staff are always interested to hear what others are doing in the astronomical community.

During the run:

Our mountain observing support staff provides most of the support for observers on Cerro Tololo itself. For the V. M. Blanco 4-m Telescope, each instrument has a scientific staff contact [12] for additional help. The smaller telescopes are operated by the SMARTS Consortium [13], and queries should be directed to SMARTS personnel.

At the end of every night at every telescope, a report form must be filled out. At all telescopes this is the responsibility of the observer. The observing assistant (Blanco, SOAR) will remind the observer to fill out the form as necessary.  For the Blanco the form is here [14].  At SOAR, the operator will indicate the location of the link.  At SMARTS telescopes, please follow their protocol.

2018 Ephemeris [15]data for Cerro Tololo (be careful of winter/summer time). (Other years: 2015 [16] - 2016 [17] - 2017 [18] - 2018 [15] - 2019 [19] - 2020 [20] - 2021 [21] - 2022 [22] - 2023 [23] - 2024 [24] - 2025 [25] -2026 [26] - 2027 [27] - 2028 [28] - 2029 [29])

CTIO runs a Target-of-Opportunity program which may require that your observations be interrupted.  The official policy is here [30].

You may wish to review the weather rules for closing and re-opening the Blanco telescope. [31]

After the run:

In order to make sure that we stay competitive as a front-line observatory, we need to know how successful your run was. PLEASE fill in one of these forms before you leave CTIO!: End-of-run report form for all CTIO telescopes [32]

GENERAL INFORMATION

If you have any questions that are not covered by the information in this document, please contact:

Ximena Herreros (xherreros@ctio.noao.edu [33])

For urgent telephone messages and importation of equipment, please contact:

Orion Wiest (owiest@aura-astronomy.org [34])
Tucson Office - P.O. Box 26732

NOAO can permit its installations to be used only by those observers who are associated with the proposals granted telescope time. Even then, because of our limited facilities we can permit no more than two observers per telescope, unless this imposes clear limitation on the data-taking. Authorization to add an investigator to a proposal must be requested from the Director's Office (xherreros@ctio.noao.edu [33]). Also, we can only grant travel support to thesis students from US institutions.

back to top

SUPPORT FOR THESIS STUDENTS FROM U.S. INSTITUTIONS

Graduate students observing at CTIO for their Ph.D. thesis research qualify for "full" travel support. Under this policy, CTIO will either pay for or reimburse the traveler for the minimum available airfare from the traveler's point of origin to La Serena and return, as well as:

  • lodging and meals at Tololo during the run
  • lodging in the La Serena motel for 2 nights
  • reimburse taxi transfers between bus stations/airports and CTIO facilities

The procedure requires that the thesis advisor send an e-mailed letter to noaoprop-letter@noao.edu [35] at the same time as the proposal; this letter must certify that the program is directly related to the student's thesis work and the competence of the student to carry out the proposed observations. This policy applies only to graduate students affiliated with U.S. institutions, whose travel originates in the United States and are observing for TAC assigned programs. (Graduate students granted Discretionary time, or those added to a proposal after time has been assigned, will be charged the standard rates).

Principal Investigators are responsible for the behavior of graduate or undergraduate students who accompany them to CTIO.

Graduate students who qualify for travel support must contact Ximena Herreros (xherreros@ctio.noao.edu [33]) at least six weeks prior to their trip, so that she can inform them about their trip to La Serena.

We strongly encourage graduate students to obtain their tickets through Teplis Travel Agency.  A Travel Agent will contact the graduate student and help him/her to book the air tickets; the cost of the trip will be direct billed to NOAO. If purchasing tickets through another agency, the student should be aware that reimbursement will be subject to an “approved rate” and the presentation of a Travel Expense Report Form. The Expense Report Form can be filled out with Ximena Herreros in La Serena.

CHARGES FOR VISITING ASTRONOMERS

Visiting astronomers will be charged actual expenses in Chilean pesos. Thus costs for lodging, meals, transport and rental car will fluctuate when expressed in US dollars, depending on the exchange rate. You should budget around $135 per night. Note that we prefer to be paid using a credit card, the transaction can take place either on Tololo (Round Office Building) or in La Serena (Treasury Office) at the end of your observing run.

The following fees will be charged to visiting astronomers who do not receive support

  CLP
(Chilean Pesos)
La Serena Facilities
Motel Room 43,660
Cerro Tololo Facilities
Motel Room 33,850
Meals (each) 15,040
Carry-all (one-way ride) 54,150
Car rental (daily) 6,000
Cerro Pachon Facilities
Motel Room 50,051
Meals (each) 15,040

 
Accounting Office is able to offer visitors the choice of paying their bills for services with Master, Visa, Diners, American Express, or Magna credit cards, in addition to the options for paying in cash (only in La Serena).

TRAVEL ARRANGEMENTS AND REIMBURSEMENTS

Visiting observers (except graduate students) are responsible for obtaining their air tickets between the point of origin and La Serena (round trip). Observers should contact Ximena Herreros (xherreros@ctio.noao.edu [33]) at least four weeks in advance of their departure date to request the reservations they need at the Observatory facilities. Observers should bear in mind that last-minute changes may be difficult to arrange and could cause delay in the itinerary.

NOTE: During the "Summer" period (December to March), note that there are very long queues at Santiago immigration at the time of arrival of the "usual" flights from the US making it sometimes difficult to catch the first flight to La Serena. Those with "O.I. cedulas" can use the diplomat line to speed getting through, but that's not an option for visiting astronomers.

 

It is imperative that we receive the Travel Information Questionnaire [9] at least four weeks prior to the start of your run. This allows us to accommodate your travel plans and lodging needs, and is submitted via the www. Before buying your air tickets, please check the carryall schedule to/from the mountain.

back to top

VISAS

Visiting observers with U.S. citizenship may enter Chile as tourists, and as such will require a valid passport. You will be given a "tourist" card by the airline bringing you to Chile. Please attach the card to your passport and safeguard it as it is required upon departure. A tourist visa can last for 90 days, however we ask that you please advise Ximena Herreros at the time that you initiate travel plans, if your stay in Chile will extend beyond 80 days. Visiting observers from other countries should consult with their travel agents, well in advance of their travel time, regarding current visa requirements for Chile.

CURRENCY

U.S. dollar exchange rate fluctuates daily, so please check the rate before you depart for Chile (see official Exchange Rate Table [36]). Pesos can be obtained at the Bank located to your left as you exit from Customs at the Merino Benítez International Airport in Santiago (also referred to by its former name "Pudahuel"). We recommend that sufficient funds be exchanged to cover incidental expenses such as taxis and meals that you will incur in Chile; costs of these services are comparable to those in major U.S. cities. At present, as the banks will not change pesos back to dollars for departing travelers, you should take this into account when buying pesos on arrival. You may also exchange dollars for pesos at the Treasury Office. If you find that you have an excessive amount of pesos as the time for your departure from Chile approaches, you would be well advised to convert them back to dollars at the La Serena Accounting Office; Accounting will exchange, as a maximum for official visitors, only the amount of pesos which was exchanged via Accounting upon arrival at CTIO. You should advise the accountants of your needs before 11:00am on the last work day prior to your departure (ext. 283).

CUSTOMS PROCEDURES

 

United States export - Chile importation procedures

Regulations concerning the exportation of equipment from the United States are very specific. Certain items including personal computers, electronic equipment, and other optical equipment are not allowed export unless approved by either the Department of Commerce or the State Department. If you intend to bring equipment to be used during your observing run or data reduction, you should contact the Tucson Office (Orion Wiest, owiest@aura-astronomy.org [34]) as soon as possible after being notified of your proposal's acceptance so that the exportation of the items can be determined (at least a month before your departure). A considerable length of time may be necessary to obtain the proper approval for certain licenses.

The Tucson Office will assist observers in obtaining the appropriate export licenses required by the US Federal Government, and will offer guidance in observing the shipping precautions necessary to secure a swift, and safe dispatch of the equipment. They may also obtain reasonable freight rates by using our present carriers.

Chilean importation procedures require full documentation, in which case the Santiago Office must present documents to the appropriate Ministry at least ten days before your arrival. To prevent inconveniences for everyone, please be certain that we are fully informed well in advance of your departure.

Please note that all equipment must be sent to Chile in the name of AURA, Inc. with the name of the principal investigator added in parentheses.

Upon arrival at the Chilean Customs you have the choice of taking either of two lines, the "Nothing to Declare" or the "Declare" queue. Custom agents may ask you to place one or more bags through the X-ray machine or have you open one or more bags even if you do chose the "Nothing to Declare" line. Visiting observers who are bringing observational equipment, may be met upon request at the Santiago airport customs area by an AURA representative and assisted in-transit to La Serena.

As in many international terminals it is advisable that you keep an eye on your bags at all times.

Luggage Claims (i.e. missing pieces of luggage on arrival...)

To process a claim for missing luggage, the owner must fill in a form that is supplied by the airline, and leave it along with the keys (or combination number to open the suitcases) and passport number at the Director's Office in La Serena. We remind you that the luggage will probably be opened by custom agents for routine checks.

IMPORTANT NOTE

  • If you want your laptop, ipad, iphone,etc to work on the Network, please fill in the Network request form [7] before you arrive, remember there is a MAC address for the wireless port and another for the wired port.
  • For safety reasons it is strictly forbidden the consumption of alcoholic beverages while your are observing or working at the Observatory.
  • It may be advisable to slightly restrict your diet while in Chile, avoided uncooked shell fish, vegetables, and tap water.
  • The water in the La Serena Compound, on Cerro Pachon and Cerro Tololo is carefully treated, although we recommend you to drink bottled water, soft drinks, instead of tap water.
  • If you have any dietary restrictions please contact Ximena Herreros to inform her of your special requirements.

TRAVELING TO LA SERENA

By Air

LAN Chile and SKY Airlines offer daily flight service between Santiago and La Serena, departing from the Domestic Terminal; the flight time is approximately 50 minutes. For current flight schedules online please go to LAN.com [37] & Skyairline.cl [38].   Visiting observers should also be aware that the free baggage limit on domestic airlines is 23 kgs. If your luggage is far over the limit, you may have the Santiago Office arrange to send the bags to La Serena on a bus line.

By Bus

Bus lines with sleeper seats serving Santiago/ La Serena/ Santiago are: Buses Libac, Pullman, Romani, Tur Bus. They all arrive and leave Santiago from the San Borja Terminal. One-way fare is approximately US$30 (16.000 pesos) depending upon the bus line, and the trip takes approximately seven hours. All buses have two drivers , a stewardess, and bathroom. For reference, there usually are departures from Santiago to La Serena or vice versa several times a day.

back to top

ARRIVAL IN LA SERENA

When arriving by plane at "La Florida" airport in La Serena (see La Serena Maps [39]) , you can take a taxi to the AURA compound (directions in Spanish for the driver are given in the next paragraph).  The cost from La Serena airport to the AURA compound is ~US$ 12 (7.000 pesos).

"Lléveme a las oficinas de AURA, o Cerro Tololo, están en Colina El Pino sin numero, esquina de calle Huanhualí con Cisternas"

If you arrive at the Terminal de Buses, (bus station) the taxi charge is ~US$ 6.00 (~4.000 pesos).

Our office hours are 8:30 am to 5:30 pm, when arriving within that time frame please come by Reception to get your envelope with motel key, visitor account and any other material/information we need to hand you. Should you arrive after office hours, this envelope will be at the main guard station on Cisternas street.

CHANGES AT THE LA SERENA MOTEL

Visiting observers can make use of the NEW AURA Compound Motel [40] for overnight lodging in La Serena.  With the start of the construction of the new office building and data center for LSST, the La Serena motel was moved from its current location and accommodation to House 9.  House 9 (or Casa 9) is located just east of the office buildings and the old motel building.  The house consists of four bedrooms each with an adjacent bathroom, a kitchen, living/dining area, and a visitor bathroom.  There is a large patio associated with the house, for which we will provide some furniture.  In the longer term, we might fit 4 or 5 extra rooms in the back of the garden, depending on the demand for the hotel.

Visiting astronomers in transit to/from the mountains may request day use of the lounge and visitor bathroom at Casa 9 if they have a long wait for their flights. See location map [41]

back to top

GETTING TO TOLOLO

Observers, particularly those unfamiliar with the instrumentation they are scheduled on, are encouraged to arrive on the mountain a day before their run begins so they can look over-the-shoulder of the previous observer, if the schedule so permits. Arriving a day early is also permitted to allow acclimatization. You can request this on the Travel Information Questionnaire. Those arriving early should take care to disturb the scheduled observers as little as possible. Assistance from Observer Support personnel will only be available on the days that a program is scheduled. Computer terminals are available in the Library and at the entrance to the 4-m telescope, note that scheduled observers and Telops have priority for use of the latter. Ethernet connections are available in the dormitory rooms.

Implementation of New Meal Registration System

This new system uses tablets on which you can register for a meal entering your last name.  The tablets are located at both casinos (Tololo and Pachon) near the self-service bar.  It is important that you register your meal before serving yourself.

Breakfast, Lunch & Dinner - The system will register the meal served at the time of registration when entering your visitor ID number or your last name.

Breakfast    08:00-08:30
Lunch          13:00-14:00
Dinner         17:00-18:30

Night-lunch - Night-lunch can be requested up to 14:00, and should be registered through the new registration service.  However, for the specifics of your night-lunch, you are kindly requested to use the paper forms.  If, at dinnertime, you take out a hot meal as night-lunch, you should register this is night-lunch too.

 

CARRY-ALL SCHEDULE

The carry-all takes 1.5 hours to go from Cerro Tololo to La Serena and viceversa.  Take this time into account when planning your flights, usually you will need to be at the airport 45 minutes before departure.

If you wish to rent a car while in Chile, you should bring along an international driver's license as well as your current home country driver's license.

In order to provide a better service and because of the limited cargo/luggage space in the carry-all, the following safety measures were implemented.  This applies in particular when the carry-all is being used at its full capacity of 11 passengers:

- Only 1 piece of luggage per passenger will be transported with the passenger; the rest of the luggage will be sent to the mountain on the next carry-all.  This rule will not apply for passengers that go directly from the airport to the telescopes site or back.

- Bags with personal goods and water bottles will be transported in the cargo/luggage area of the carry-all if there is space available.  If not, these items will be transported in the next carry-all.

If you plan to travel to/from the mountains with more than one piece of luggage, we suggest that you contact Patricia Valencia (pvalencia@ctio.noao.edu [42], ext. 280) or CTIO Mountain Assistants (opstol@ctio.noao.edu [43], ext. 440), so that you can plan the delivery of the rest of your luggage.

 

Before departing from Tololo

If you are not stopping by the La Serena Office upon departure, please be prepared to settle your account with Alex Jeraldo or Juan Jose Paleo (opstol@ctio.noao.edu [43]) (x.440) at the Round Office Building before leaving Tololo. We request that visitors bring credit cards (Visa, Master, American) to cover expenses such as lodging and meals at the Observatory facilities, personal calls, transport, etc. At this time payments in cash (Chilean pesos or U.S. dollars) can only be made in La Serena.

IMPORTANT NOTE:  Tololo Hotel checkout is at 11:30 am.  CTIO visitors must settle their bills immediately after checkout at the Round Office Building.  The carry-all departs from this building at 12:10 pm SHARP (NO DELAYS).

If you are stopping over in La Serena after your run, please settle your bill with Evelyn Araya (earaya@aura-astronomy.org [44]) at the Treasury Office (x283).

Director's Discretionary (DD) Time

update

The Observing Schedule as prepared at the start of a semester sometimes has some nights unscheduled, more commonly on the smaller telescopes. For the latter, please consult the full small telescope schedule on the SMARTS WWW page [49].

In order to apply for DD time please send an email to the CTIO Director [50], with copy to Ximena Herreros [33]. In this email include the name and affiliation of the P.I. and collaborators, together with the telescope and instrumental configuration required. Although time is allocated to the best science, you should assume that the instrument already installed will be the only one available. Then,

  • EITHER: For a new project, write a short (one page or less) scientific justification.
  • OR: If you writing in respect of a project for which time has been awarded, then just quote the proposal semester and number code, and justify why you need extra time.
  • OR: If you writing in respect of a project which was rejected by the TAC, quote the semester and number code, and then justify why you think you should be given time.

Please note that DD time is treated at lower priority than regularly scheduled time in case of resource conflicts, and we cannot offer any financial support. Apart from that, once awarded, DD time is considered to be just like normally scheduled time.

ToO Policy

CTIO Blanco 4-m Telescope
Target-of-Opportunity Observing Program Policies

For the attention of: CTIO staff, Blanco 4-m telescope observers, CTIO Blanco 4-m telescope ToO program principal investigators.

Updated on: 14 August 2014

CTIO follows the NOAO Target of Opportunity observing program policy (http://www.noao.edu/noaoprop/help/too.html [59]) with the addenda given below for the V. M. Blanco 4-m telescope. We thank observers for their forbearance and co-operation with these policies

A) Before triggering your first interrupt

Communications with the observatory regarding your ToO program should be made by email to DECamToO@ctio.noao.edu [60]; please always include the propid of your program in the subject line of any messages. 

 

This email alias includes the CTIO Director and Deputy, the DECam Instrument scientist, and the other members of the CTIO scientific staff comprising the DECam support team.   It also includes members of the Telescope Operations Staff, in Chile, and the data management staff in Tucson who are responsible for handling and pipeline processing the data. Communicating through the DECamToO alias is the only way to ensure that everyone who needs to know about your ToO program is kept in the loop.

At the beginning of the semester well before triggering your first interrupt please send an e-mail to DECamToO@ctio.noao.edu [60] in order to:

  • Check communication
  • Identify the individuals authorized to trigger ToO events.  Only the PI of the program or their deputy previously authorized by the PI, are allowed to trigger observations. Requests from others will not be acted upon until we are able to confirm the request with the PI.
  • Touch bases with the Support Scientist assigned for your program (hereinafter referred to as the ToO Support Scientist).  They will work with you to plan your observations to the extent possible in advance, and in particular will help you develop a template DECam observing script which can be edited according to the specific circumstances of an event and then executed in order to carry out the required observations.
  • Make contact with the data management folk to discuss any special data processing needs for your program (e.g.  moving object detection)

B) Call-up Procedure

ToO events can only be triggered during NOAO community access time. That is they cannot be triggered on nights assigned to the Dark Energy Survey (DES), nor on nights assigned through the Chilean or AAO TACs

The regular observer and observatory support staff should hear about a ToO as soon as possible, preferably no later than the afternoon of the observing night. This allows time for email back and forth with the PI of the ToO program, and for making any necessary preparations. 

To initiate the process of triggering an observation for their Target of Opportunity Program, the approved program PI or specified deputy must send e-mail to DECamToO@ctio.noao.edu [60].

For each night when DECam is in operation a member of the DECam Scientific support team (all of whom are included in the DECamToO alias)  is "on duty" to support the scheduled observer either on the mountain, or remotely in la Serena.    On receiving the email the support scientist “on duty” will inform the scheduled observer about the ToO, and will work with the PI's of the ToO and scheduled program to coordinate the collection of the required observations.  The ToO Support Scientist for your run may also become involved, but, given the unpredictability of timing, should not be assumed to be available for any given event, hence the importance of careful coordination via the email alias.

C) Data taking

 

  1. The current observer will be asked to take the ToO data by executing an observing script. This observing script should be prepared by the ToO team with the help of the DECam support scientist on duty, using the template observing script developed in advance as a starting point. The ToO PI or deputy must send this script and any supporting information and instructions to the DECamToO@ctio.noao.edu [60] alias.
  2. Any images taken specifically for a ToO program must be identified with the NOAO propid of the ToO program to ensure that the data is correctly labelled in the NOAO data archive. Fixing incorrect propids post facto is possible in an emergency but very time consuming. See http://www.noao.edu/noaoprop/too/ [61] for a list of current approved ToO projects.
  3. The scheduled observer should note in their night report whenever a ToO observation is requested, and record the amount of time that was dedicated to the ToO

ToO Data Files

Data obtained for ToO programs will be transferred to the NOAO archive and will be processed through the community pipeline as for any other community program. Note that you will only have access to your proprietary data if it has been obtained with the propid of the ToO program.

Typically raw data appears in the NOAO Science Archive within a couple of hours of the end of the exposure.  Hence all raw data will be accessible through the NOAO Portal (http://portal-nvo.noao.edu/ [62]) within a couple of hours of the last observation.  However, in atypical situations hardware or internet problems may delay data delivery.  If quick access to the data is critical for the science then please tell us know so that someone from the data transport team can advise the PI should a delay occur.

Typically pipeline calibrations are performed on all data from the observing block within which the ToO interrupt was included.  Therefore, calibrated data should be available from the NOAO Science Archive within a week of the end of the run.  If a quicker turnaround, within a few days of the observation, is essential please communicate this and someone from the pipeline team will respond.  But please don't request this unless it is really science critical.

It is possible to perform special processing in the pipeline to detect fast moving objects for example to recover near Earth objects.  For this observations should consist of 5 to 10 consecutive or interleaved exposures.  Please let us know in advance if moving object processing is required for your observations.  Note that moving object detection and fast turn-around requests may be combined.
