              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
High clouds accosted us for most of the afternoon and evening, finally clearing up around 10 PM. We had clear skies for the rest of the night.
After cleaning a significant amount of moth gunk off the altitude drive surface that wasn't there yesterday, we had no repeats of the altitude drive problems from last night...until the beginning of B half, where we ran into a motion error and overcurrent on the first slew (00:14 local), trying to go to low altitude (21) from an altitude of about 71. Russet then went to higher altitude (78) and slewed to the target from there, getting through the trouble spot.
We had no further issues, and the rest of the night was uneventful (with good seeing!)
