Exploring the PSFPosted by Chris Flynn Sep 29, 2011 01:46PM
Sep 29 -- Peter and Chris observed Markab -- noticed much broader halo around the stars than usual. Image below shows that this can even be seen in the sky camera.
Left: clear night from 2011-09-27, Jupiter in center of frame. Right: not photometric conditions 2011-09-29, Jupiter has a slight halo. Note that the bright "star" right above Jupiter is possibly an internal reflection (of Jupiter?) in the sky camera.
We will observe Jupiter through whatever this stuff so we can compare directly to previous determinations of the PSF.
