              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
DIS RED camera appeared to need to be power cycled (This occured on Thursday night as well but I forgot to mention it).  Bias image looked odd with horizontal line/streaks in it. I decided to try another bias frame first to make sure it didn't clear itself before I took more drastic measures (power cycle).  The image looked fine after the second bias (this was not the case on Thursday when it happened).  Calibration spectra also looked fine after the 2nd bias as well.
Pesky clouds during the 2nd half of the night.
