Seeing was good for the whole night. We observed 7 plates, 6 of them are done. 45 min was lost to thick clouds Cart 14, plate 5196. DONE cart 17, plate 5063. DONE. cart 12, plate 5146. DONE. cart 13, plate 4361. DONE. cart 15, plate 4415. DONE. cart 10, plate 4669. DONE. cart 18, plate 5106, Problem: 1. Please check pressure relief valve on deward #7. It would not stop to spray out air (with a little LN) even when the pressure was below 20 PSI. 2. "goto Instrument Change" refuses to move the telescope during the reading out of a stopped exposure. ---- Observing Log ---- Afternoon: ---------- All actors and systems were checked out, no problem to report. Cartridge bay was checked out, confirmed the leg control lever is in the observing position, and all boss cartridges are in the bay, positioned correctly, and requested plates are in platedb. At 00:20Z, we noticed that the pressure relief valve on deward #7 would not stop even the pressure was down to 17 PSI. Mark stopped it by hitting the valve. Night: ----- 00:30Z started to open the west door manually. 00:55Z enclosure off. 01:25Z cart 14, plate 5196. gotoField. Applied our magic offset (-0.005, 0.002) to get stars.
