Comments: 

The first half of the night had partial clouds but extended periods of low sky brightness and sub-arcsecond seeing. In the second half of the night the cloud cover was close to 100 percent, with the seeing, psf ellipticity and sky brightness fluctuating. The exposures for much of the latter half appear unlikely to be acceptable.
