The final campaign for Fermi Cycle 6 starts out with a difficult night.
The night wasn't totally useless, but clouds dominated and there was even a
brief, light spritz of rain early in the evening. About a half dozen, mostly
bright blazers were successfully observed for polarization. Very little
photometry was attempted. The seeing was excellent (1-1.5 arsec, or better) during the few hours that the dome was open.
