Observer: Kara Ponder
Telescope Operator: Krissy Reetz
Conditions:
wind: 24.5 mph 
Humidity: 17 %
Temperature: 9.9 C
Seeing: 1.0
Moon: 97%

Notes:
Partly cloudy through the night but cleared up around 2:30 am. Windy all night causing some problems.

Had many triangluar contour plots. 

The WTTM slide was stuck in the position to let light to WHIRC instead of the OA, so we had to check pointing by taking images and adjusting by eye. 

We used WTTM on three targets: PSNJ08593491+4555343, PS15mb, and ASASSN-15fs. 

Tried to observe iPTF15vw and did one iteration of 5x5x15" to get an integration time of 25 minutes, but wind shake was extremely bad. No way to focus and barely holding regular guide star. Moved to a target that we could get better data on.

We took 569 images.
