*Observing Plan*

# standard bias and dome flat sequence

# evening standard stars

# run ObsTac queue

# morning standard stars and bias

*Conditions*

# Weather at 10:30PM: Clear, but winds around 10mph. Wind screen is on.

# 12:30 AM, winds have gone down. Screen off.

# 1:30 AM, quite a few clouds in the eastern sky. (On the positive side, blocking out the moon.) A few thin clouds overhead but overhead skies still very clear overall.

# 3:00 AM, had some clouds in the past hour. Now clouds back to only really in the East. Wind has picked up quite a bit and wind screen was put on.

# 5:00 AM clouds remained on the horizon, wind stayed strong, seeing went up a bit, images went above 1 arcsec for a while but then came back down to around 0.9 on the QR.

#End of night: Conditions pretty good all night. Some clouds but mostly stayed near the horizon. Seeing (on images via QR) less than 1 arcsec most of the night.

*Accomplishments*

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

# Evening: Standards (SDSSJ2140-0000, SDSSJ0320-0000, SDSSJ0100-0000)

# Overall: Supernova SN-C2 (387014-387019), Survey (387020-387234)

# Morning: Standards (SDSSJ1227-0000, MaxVis, SDSSJ0843-0000) and biases
