Observer: Kara Ponder, Anja Weyant until ~12
Observing Assistant: Dave Summers
Wind:15.7 mph
Humidity: 37%   (80% by morning)
Temperature: 7.5 C
Seeing: 0.65-0.9 
Moon: 91%


Notes:
Used WTTM the whole night. Dave did ~5 minute tests for Charles before starting dithers on most of the supernovae.

To observe with WTTM it is necessary to have a star brighter than r=14.5 in the field of view.  We were able to use WTTM for all SN targets although we made offsets for some of the targets to get a bright star within range.  Here is a list of offsets:

2013fw: 30" S and 30" E *** This was mistyped on the Observing Report from 20131209. 
iPTF13ebh: 45" W


Lost an hour of observing time due to issues with ds9 and pyraf not finding the images to do "imexam" on to focus. 

Seeing was fluctuating between 0.8-1.2 so I added 9 minutes to iPTF13dge in the J band. 

Cut the J band in LSQ13crf due to time contraints plus variable seeing.

Lost guiding on images 506-508. Stop dither and refind the guide star for WTTM. 

Took a total of 579 images.
