Adler observers:  M.Hammergren, M.Brucker, K.Nault, M.Nichols, K.Walczak
With the sky being so bright during twilight, I estimated focus based on the slitviewer images to be ~1.2".  I decided it was better to hand it over to Merida than continue fighting with the focus script.
We battled thin to heavy clouds all night.  Once things got bad, we were on very bright targets, so we were able to push through.  Seeing stayed excellent until the last few hours.
Apollo software crashed right before we swapped programs, and was unfixable.  Russet ceded the hour to UW10.  Adam could only use a small part of that extra hour, so we closed a bit early.
