* Observing Plan

# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# end of the night standard star
# end of night calibrations

* Conditions

# weather in afternoon: 5:03pm (local): Clear blue skies overhead, a few scattered clouds near horizon, winds ~8 mph, 10C, ~55% humidity
# weather after dinner: 7pm (local): clear, no clouds, wind~8mph, 10C, 55% humidity
# weather after sunset: 9pm (local): clear, no clouds, haze in the East, wind~5mph, 10C, 60% humidity
# weather during night: ?pm (local): clear, no clouds
# weather summary: clear, 10C, low wind (hovered between 5 and 10)
# Seeing conditions: 0.8 (rms 0.1) and 1.1 (rms 0.05)
# Wind conditions: low most of night; had to raise blind and louvers around 0200(local).

* Accomplishments

# Afternoon: zeros done, (ugriz) dome flats done, flats checked
# Evening: Standards
## SDSSJ 0100-0000
## SDSSJ 0000-0000
## SDSSJ 2140-0000
# Survey Exposures:
## before moon-set: z,Y
## after moon-set g,r,i
## SN-S2 in early night
# End of night: Standards (0547hr local)
## SDSS J0958 – 0010
## SDSS J0843 – 0000
## MaxVis

* Problems tagged as Synopsis_Problem
## Rasicam: off
## ~10min lost to shutter controller error: reset at Telops Console by Telops
* Notes for Data Management

# Shutter controller error caused loss of exposure 372566. Obstac repeated the same field/hex on the next exposure.
