Happy New Year! The first Fermi/Steward Observatory monitoring campaign of
2013 starts with a decent, but very cold night on Kitt Peak at the
The major weather action occurred during the previous night, when a
serious cold front swept through Arizona, bringing high winds and some snow
to the mountain. As a result, the primary mirror
was nearly 10 deg F warmer than the air temperature at the start of the
night, leading to seeing of around 3 arcsec.
By midnight the seeing had improved to about 2 arcsec.
Despite the less than great seeing, this was a very productive night
both in terms of spectropolarimetry and spectrophotometry.
