*Observing Plan*

# standard bias and dome flat sequence

# evening standard stars

# run ObsTac queue

# middle-of-night standard stars

*Conditions*

# 9:30 (start of observing) - clear sky, windspeed average ~4.5 mph. Stayed mostly constant through the half night, though wind went down a little.

# Seeing conditions - Median: 1.36, RMS: .49 (from QR stats page). DIMM seeing started out at ~1.5, decreasing through the night and ending up at ~.9 by night midpoint.

*Accomplishments*

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

# Evening: Standards (E3-A, MaxVis, SDSSJ0200-0000).

# Overall: SN - S2, S1, C1, X2, X3, C3 (392300 - 392323, 392325 - 392347), Wide Survey (392324).

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