              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Arctic wasn't reading out properly at checkout.  All the quads were over 20K counts and each quad was different by thousands.  An arctic init was executed and, while the UL quad did drop out, the rest began responding normally.
We focused the ecam guider and took a new slit mask and updated the instrument block.
Things were windy all night and we never opened.  It started snowing around 7pm and continued for about 3 hours, dropping several inches of snow.  I ran the snow program until the winds became too high (>40 mph). There was a power went out around 00:45 and was out for a few seconds.  The generator came on but we were never on generator power and it shut itself off.
The telescope is pointed south and it's supposed to be sunny all day tomorrow so maybe enough snow will melt to allow us to open...
