The Bok Telescope on Kitt Peak, AZ hosts Fermi/Steward Observatory Campaign
91. The first night of the campaign had plenty of clouds and bright moonlight.
The moonlight will be a fixture during the entire campaign, but hopefully the clouds will not be as much of a nuisance as they were tonight.
Despite the clouds, this was a very productive night, with almost 20 blazars
measured for polarization. Multiple observations of CTA102 were made through
clouds and it is still exceptionally bright. Unfortunately, photometry of most objects,
including CTA102, could not be obtained given the cloudy mess in the sky.
The seeing was 2-2.5 arcsec early in the night, but improved to 1.5-2 arcsec later on.
