Observer: Kara Ponder with Jess Kroboth and Cat Fielder for first few hours
Telescope Operator: Karen Butler
Conditions: Clear 
wind: 12 mph
Humidity: 49  %
Temperature: 5.6 C
Seeing: 1.5+, range from 0.9 to 2.8"
Moon: 62%

Notes:
Seeing got to ~2" around 10 pm and stayed  high for the rest of the night.

We tested out the new pointing camera which takes a picture of the sky and and calculates how off we are from the input RA and Dec. It does okay: one target was correct and one needed ~30" shift. 

Dust was running out of disk space which gave a warning every time a frame read out. I deleted 6 nights of our observations that I had confirmed that we had data for. Karen emailed Dick and it was sorted out the next day. 

We used WTTM on PS15mt (dropped after a few dithers and switched to regular guiding) and SN2015G. Seeing was too high to use it except for very bright guide stars. 

We took 531 images.
