APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 7, 2007 (MJD 54139) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Elena Malanushenko Shannon Watters ---=== OBSERVING PLAN ===--- 5c13nc3! ---=== OBSERVING SUMMARY ===--- The night started with mostly clear skies. We were able to finish 3 plates and get signal on another before a combination of cirrus clouds and the moon ruined our exposures. We did finish the night with a good exposure on a fifth plate (not done). We had a problem with a forced-fill of sp1 at the beginning of the night (problems). ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon check completed. No problems encountered. Spectrograph focus checked but not adjusted. Best focus around 6 to 7 C. 00:00Z Doors Open, Louvers Open, Fans On. Night: ------ 01:20Z Cart 9, plate 2419, chunk135. Plate doesn't start until 02:25Z so we won't start science until 5 minutes after twilight ends (02:05Z).

After it appeared to finish I went out to disconnect the cryo lines but sp2 repeatedly filled for 10-20 seconds, stopped for 20-30 seconds, filled for 10-20 seconds, etc. Dan Long came out and did a force fill of sp2 and it took another 11.5 pounds before it was full. He did the same for sp1 (just in case) but it was already full. The total fill was 42 lbs.
