Date: Tue, 11 Oct 2005 13:53:27 -0500 (CDT) From: Stephen Kent Subject: Re: 2.5m obslog 20051010 (MJD 53654) Observing crew - Brian Yanny and I looked at the coverage of run 5711 on 79 N last night. We haven't processed the data yet, but based on the cloud camera data, which show clouds right in the middle of the scan, and the fact that the scan stopped short, we think it best to reobserve the entire scan. Sorry about that.
