              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started clear but with only moderate seeing.  However, clouds started to roll in around 23:00. Rain was a few hours behind.  GS01 was not able to see their galaxies and we closed at 03:19 when the rain became too close. It started raining at 03:32 and continued the rest of the night.
ARCTIC took good biases at checkout but, after mounting the instrument, the exposures were bad (all pixels were the same value at 26194). An arctic init command did not work but restarting the Nubs did and there were no more problems for the rest of the night.
Tspec was corrupt at checkout and I power cycled it, leaving it off for approximately 5 hours. Before powering it back on I rotated the instrument and filled the Aux tank.  After turning it back on, the first four images were good but with hot spots.  The next ~225 were perfect but then became corrupted again.
