Weather Report for September 26, 2011

The official start of the Fermi Cycle 4 observing campaigns begins in rough fashion. Right at the start of the night there was a catastrophic failure of the dome rotation motor control. Over four hours were spent replacing a complete motor control unit with a spare and configuring the new unit so that the dome could be rotated with only one of the two motors operating. Serious observing started at just past midnight and about a dozen blazars were observed in clear skies with seeing that ranged from 1 arcsec up to just over 2 arcsec.

Thanks go to Bill Wood (Bok Telescope site supervisor) and Jeff Rill, who managed to salvaged a half night of observing after an unprecedented failure of a major piece of hardware.
