Notes:
No suitable guide stars for WTTM. Used http://www-kpno.kpno.noao.edu/cgi-bin/kpno-misc/wiyn/WTTMtooltest.pl as an indicator of guide stars. Works fairly well but it will sometimes suggest the galaxy as a guide star. 

Since 2014J is still visible but is very faint, we needed to slightly change the way we observe it. I ran a dither sequence on sky, then a 5 second dither sequence on the target in order to not saturate the star used for calibration, then I did the full 1 minute exposures for the amount of time we would need to expose for a good signal to noise. Once done I went back to the 5 second calibrating sequence and then back to a sky dither sequence. I ran out of time to do this for all three filters.

We took 693 images. One image failed to read out.
