              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Poor CU08.  We were basically overcast until nearly midnight, not even the moon was visible.  When we did open there were still lots of clouds that kept things at either no photons or saturating making it impossible to focus or even calculate a rough focus, so I just tried to make the saturated spots round.  However, the clouds parted for JH02 and they had good seeing and basically clear skies their whole half.  So what ever he's doing, we gotta do that.
At one point when I went to slew to a focus star, I was given a tcc timeout error
track 179.... failed: Timeout; Actor='tcc'; Cmd='track 179.0408333, 15.5938889 FK5=2009.5/Name="95 Leo"/RotAngle=0/RotType=Object/Magnitude=5.53'
However, I executed the slew again and everything was fine.
