*Observing Plan*

# standard bias and dome flat sequence

# evening standard stars

# run ObsTac queue

# morning standard stars and bias

*Conditions*

#09:30pm Clear sky. Quite windy at beginning of the night with wind speeds averaging 15 mph. Will wait with wind screen until after standards, though.

#09:50pm Raising wind screen

#01:00am Wind speed has been steady at 13-15 mph. DIMM seeing 0.7 on average; dome seeing(QR) around 1 arcsec.

#02:00am Thin clouds at low elevation in the east. Winds still averaging 13mph

*Accomplishments*

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

# Evening: Standards (SDSSJ2140-0000, SDSSJ2300-0000, SDSSJ0100-0000)

# Overall: Survey (387704 - 387936)

# Morning: Standards (SDSSJ1048-0000, SDSSJ0933-0000) and biases
