*Observing Plan*

# standard bias and dome flat sequence

# evening standard stars

# weekly defocus script

# run ObsTac queue

# middle-of-night standard stars

*Conditions*

# 9:30 (start of observing) - mostly clear sky - some low clouds in the west, windspeed average ~6.5 mph.

# 12:52 - wind speed up to > 10 mph - windscreen going up.

# Seeing conditions - Median: .92, RMS: .15 (from QR stats page). DIMM seeing averaged ~.7 during the first quarter of the night, and ~.65 during the second quarter.

*Accomplishments*

# Afternoon: zeros, dome flat sequence (YziVRrgu).

# Evening: Standards (SDSSJ2300-0000, SDSSJ0000-0000, SDSSJ0320-0000), Weekly defocus script.

# Overall: SNe - S2 (393035 - 393040), Wide Survey (393041 - 393151).

# Middle of Night: Standards (SDSSJ0320-0000, MaxVis)

*Minor Problems and Relevant Information*

*Notes for Data Management*

The windscreen was accidentally left up for the first few (maybe 2-4) exposures of the middle-of-night standards. However, it was pretty low, and the images look ok, so not sure how much it has affected them...
