Observing Plan:

  1. Three sets of evening standard stars and dome flat sequence
  2. Run ObsTac queue
  3. Three sets of morning standard stars and morning bias exposures

Conditions:

  1. Clear at start of night, with clouds to the far west, south, and north seen early (before sunset)
  2. Thereafter, clear as far as could tell from direct observations.

Accomplishments:

  1. Afternoon bias and flats run; with similar results to previous couple nights.  Only g- and Y-band within desired tolerances.  u-band with dark spot in center of CCD array, and VR-band with considerable CCD to CCD variations
  2. Evening standard stars taken

    • E1-A
    • SDSSJ0000-0000
    • SDSSJ2140-0000
  3. Took wide angle survey exposures
  4. Took SN field

    • S2
  5. Morning standard stars taken

    • SDSSJ0958-0010
    • MaxVis
    • SDSSJ0320-0000
  6. Morning bias measurements
