ENR CTIO Blanco 4-m 2014-10-19

Date: 
Sunday, October 19, 2014
Telescope: 
CTIO Blanco 4-m
Submitter: 
Hal Spinka
Submitter Email: 
hms@anl.gov
Observer Support: 
Rodrigo Hernandez
Night Assistant: 
Claudio Aguilera
Also Present: 
Ann. Elliott, Kathleen Grabowski, Hal Spinka
Problems: 

flatCheck plots indicated problems with r and somewhat i-band flats, plus VR and u-band flats.  The u-band had a dark hole in the middle of the CCD array again, as last night.  The VR flat appeared to have problems.  No explanation for the i- or r-band problems indicated by flatCheck.

Mirror air support lost again, just as yesterday, during standard stars again ~8:50 pm local time.

Comments: 

Observing plan:

  • Afternoon zeros, dome flats
  • Evening Standard Stars

    • SDSSJ0000-0000
    • SDSSJ2300-0000
    • SDSSJ2140-0000
  • Wide survey images
  • Supernova fields, which were found bad from yesterday
  • Morning standard stars

    • SDSSJ0933-0005
    • SDSSJ0320-0000
    • MaxVis
  • Post-night biases

Accomplishments:

  • The dome flats were taken.
  • Evening standard stars were collected in all 3 fields
  • Approximately *** images in the wide survey were collected
  • Supernova deadman images were collected in the supernova fields:

    • C3 (g and r)
  • Morning standard stars and biases were completed

Other::

  • Long straight tracjs observed ib exposures 369322 and 369451 (2 crossing tracks).  The tracks seemed to be solid lines, so maybe from meteorites??
