Observer Support: 
Manuel Hernandez
Night Assistant: 
Alberto Alvarez
Also Present: 
Brian Nord, David James, Anna Patej, Adam Meyers
Problems: 

1st Half:

Observations ceased one-quarter of the way through the night, because DECal lamps were on inside the dome.  25 minutes lost.  David James and others did the troubleshooting and resumed operations.

2nd Half

None

Comments: 

 Observing Team

DES Observers: David James, Stephen Kent
Telops: Manuel Hernandez, Alberto Alvarez
Remote Support: K. Honscheid, E. Neilson spying

Observing Plan

  1. use 1st half standard bias and dome flat sequence
  2. two mid-point standard stars
  3. run ObsTac queue
  4. three morning standard stars
  5. morning bias

Conditions

  1. Clear all night
  2. Good seeing most of the time

Accomplishments

  1. afternoon bias and flats; flats look good
  2. Smooth transition from 1st half observers at 04:47 UT
  3. midpoint standards

    • SDSSJ0100
    • SDSSJ2140
  4. SN Fields

    • E1
    • C3 g, r, i, z
  5. Wide survey i, Y, z exposures
  6. morning standards

    • SDSSJ0000
    • SDSSJ0100
    • SDSSJ0320

Problems

  1. None

Notes for data management

  1. Afternoon flats and biases 348107-348204 are from prop-id 2014B-0404
  2. Do not process 348496, 348502, 348508 (hexapod update)
