Campaign 73 finishes with a good night and many blazars observed. The sky was clear until the last hour of the night, but quite hazy due to many distant wildfires in Arizona and California. It is that time of year. The seeing was 1-2 arcsec and much improved over the previous night. During the last hour, light cirrus from decayed thunderstorms in northern Mexico moved into the sky.
The annual "monsoon" campaign in July will be conducted at the Bok Telescope
on Kitt Peak, AZ. This will be the final scheduled observing campaign for
Fermi Cycle 7.
