Night Assistant: 
Alberto Alvarez
Also Present: 
Wilson Liu
Problems: 

In the beginning of the night, the full moon gave too much background for some of the sources. Needed to either skip them completely or cut them off at the end of their sequence of exposures. The whole night had lesser-than-average seeing in general, but the second half of the night had very poor seeing (2"-3"). Most of the time, stars could be seen through images over the background, though dimly. The poor seeing led to problems with the guider early on, but changing the exposure time for the guider to 600 ms allowed it to function better for most of the night.

Throughout the night, the humidity kept increasing from around 50% to 80% toward the end of the night. By the end, the humidity became to high and the dome had to be closed. 

Comments: 

None.

Comment: 
Dome had to be closed at the end of the night because of the high humidity. Wind speed was also high for most of the night before it dipped when the humidity increased.
