              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky

gcam needed a nubs restart at checkout,

No drive issues during initial checkout slews.  I slewed upwards first then down, per our obs spec meeting discussion.

ARCTIC had the LL quad issue during checkout images.  

No problems with Echelle ThAr lamps during checkout or during my 1st observers cals.

We had lots of clouds forming just to our west and moving over head.  Initially I wasn't sure if they had rain, as I saw a nearby cloud with virga.  I opened the dome but kept the mirror covers closed.  By 23:15 we seemed to have some clearing in the East but pretty cloudy elsewhwere.  My observers had an eastern target so I let them use the telescope as the rain threat didn't seem immenent any more.  The sky improved greatly around 23:45.
