Data logs are organized by month. Within each month the logs are filed by "Observing Date", which is defined as the local date at the start of the observing night. For example, to see what was observed during the night that began at sunset on 2005 Feb 12 and ended at sunrise on Feb 13, you would look at the log for 2005 Feb 12.
Logs are updated automatically at 11am Eastern Time. The AGN05 campaign
ran from 2005 Feb 7 thru 2005 Apr 10 (observing dates).
