APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 14, 2007 (MJD 54115) ---=== OBSERVING TEAM ===--- Howard Brewington Viktor Malanushenko Mike Harvanek (swing) Bob Pfaffenberger (support) Dan Long (support by phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Mostly cloudy, clear sky on sunset. -- At evening we mounted imager. The cloudy and bad seeing have not allowed us to obtain result. -- We observed 7th plate and have obtained acceptable signals for the 6th plates. A four of them have been declared as DONE. For one plate we could not obtain acceptable (S/N)^2. -- We asking about status Cart 6 plate 2639 -- for the both blue cam have not acceptable (S/N)^2 tonight. -- Top the web-cam (to see on 2.5m telescope) works incorrectly: very dark image (or high contrast, or lost sensitives?). We asks engineers to test and fix it, please! -- During collimate spectro to current temperature (-8.5 C) we have received message on a mistake motors. Details in to 'Problems' section. -- The humidity sensor is sounding when we closed telescope. ---=== OBSERVING LOG ===--- Afternoon: ---------- The 90 degree alt fiducial did not read in either direction. The 45 degree alt fiducial did not read going up. Spectro collimation was adjusted. Details are in the Problems section. We had a problem with the spectro autofill today. A fill started around 16:15Z and for approximately the next hour, a sequence of five fills one right after another proceeded to empty the 180 l spectrograph dewar. About 2 hours later (19:10Z), a critical alert was issued for sp2's secondary dewar pressure. A second critical error for both sp2's secondary dewar pressure and ln2 empty followed an hour later. I (Mike) arrived around 21:30Z and found Bob P. changing the spectro dewar with Dan L. advising on the situation by phone. When the dewar was changed, we forced a fill of the 10 l dewars and then forced fills on r2 and b2. Both ccds had started to warm (ccd 2 was around -73 C, ccd 3 was around -83 C) but after we forced the fills, both cooled back to normal temps (-90 C) within a few minutes. sp1 did not appear to be affected by this problem. The spectro autofill system was turned off. Spectro fills should be done manually until further notice.
