              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
There was a LOT of wind before starting for the night!  We started on generator power so it came as no surprise that the drives needed restarting and, during the first slew, there was a collision. But, after pushing the telescope off the collision pad everything moved smoothly.  Site power returned at 22:00 which resulted in a stop, but an axis init was all that was needed and no time was lost.
The nightlogFocus wasn't responding and reporting a "Failed: timed out" error.   I was not able to fix the issue (honestly, I didn't know how and neither did anyone else) so I listed focus information as best as I could.  The diffuser wouldn't move into the Out position so...I honestly don't know what the focus was, but Sloan reported about 1.5-2.5 during B half.  This fact didn't matter for UW01 as they wanted to observe with the diffuser in so...yay!
Things continued to be windy, virga, clouds, then clear, windy, but somehow not dusty!

     The convention used is north=0 degrees, east=90 degrees.
     The dust count is particles > 1u per 0.1 cubic feet.
