              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
gcam needed a restart during check out
Arcsat was semi-lost, it didn't run away but the pointing was way off and required rezenithing. hey, but that means we opened!  The rain, thunder, crazy lightning, and hail all stopped around 6pm, though there were some clouds that stuck around for awhile.  I delayed opening by 40 min waiting for the potential danger to clear. We had good to excellent seeing all night, though I seem to not have recorded the first focus with ARCTIC, which was 0.98".
JH01 was taking echelle calibrations at dawn and they aren't expected to end until after 7:30 so I did not take a dawn IOL.
