Weather Report for March 16, 2018


A full night of observing was possible tonight. The sky was photometric up until midnight and then light cirrus streamed in from the west after that. It has been rather rare over the past month to get a night as good as this. Twenty blazars were observed for polarization in seeing that varied between 1.5-3 arcsec (generally, the poorer seeing was in the first half of the night). Spectropolarimetry of about half of these objects will be accompanied by flux measurements.

There will now be a one-night break in the campaign to make way for an Astronomy Camp at the Kuiper Telescope to be followed by the final two nights of Campaign 108. The weather forecast for all three nights is not promising, as yet another storm system moves into the area.
