Chris Stubbs donated his time to UW03, so Gene Magnier was observing for the entire evening. Gene's net connection went down early in the evening, so Charles observed for him until it came back. (Charles was the observer until 20:00) Charles also notes that the T1 link was lost at 16:00 and there were some additional problems in the recovery of the CISCO router, but no time was lost. Gene then observed for the rest of the night under murky skies. He used DIS until 21:30, and then switched to GRIM2. I asked for comments on the run and Gene stated "I was able to get IR images of every target, and narrow band images of the best. It was very productive."
