              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The echelle is back!  Yay!!
Things were a little windy tonight but we had good seeing and clear skies...until clouds rolled in around 3:30.  Unfortunately, JH05 was observing ridiculously faint object, like mag=23 so clouds put a hamper on things.  They closed up a littler early at 04:45 since they could not see their object.
ARCSAT was a pain tonight.  First it became lost and took over an hour to square away issues, then there were guide problems, and it would open and close while starting/stopping dome flats even though the 2.5 and 3.5 were closed.
