APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday November 20, 2007 (MJD 54425) ---=== OBSERVING TEAM ===--- Dan Oravetz (swing) Viktor Malanushenko (observer) Howard Brewington (observer) ---=== OBSERVING PLAN ===--- SN & SEGUE Science! ---=== OBSERVING SUMMARY ===--- We were closed for several hours because of clouds and radar returns. Run # 7187 On-telescope bias Run # 7188 superNova, 82 N lambda 113.0 to 169.4 (includes the ramps) with lots of clouds during parts of the run; please see Imaging Details category for more details. Cart 04, plate 1784 was declared done. Cart 08, plate 2806 was declared done. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and working properly. As of 22:01Z there are 228G free on /data and 111G free on /files. Spectro focus set for ~5C. 23:05Z - Began ventilation. Doors and louvers opened, fans on. Night: ------ 23:20Z Mounted imager 23:57Z Sunset 00:10Z Run # 7187, On-telescope bias inside darkened enclosure. 00:30Z Pulled enclosure, filled spectro dewars, checked top/bottom balance, and did a test slew. 00:57Z Run # 7188 (superNova) scanStripe 82 S -startLambda 107.5 Seeing = ~1.3 to 1.6" as reported by seeingRun Alt = 43 degrees under partly cloudy skies muError was slightly high at 10.2" via skippy; see below.

Time had, unfortunately, run out for superNova, so we prepared to dismount the imager. 09:00Z Dismounted imager and mounted Cart 04. 09:15Z Pulled enclosure, checked and adjusted top/bottom balance. 09:25Z Cart 04, plate 1784 (chunk93). An Fk5 star was used to find the field. Clouds had cleared and the seeing was ~1.3" This plate was declared done with four exposures. 09:35 47458 10.0 flat 09:37 47459 2.0 arc 09:57 47460 901.0 target 10:20 47461 1202.0 target 10:39 47462 1001.0 target 10:58 47463 902.0 target 11:02Z Cart 09, plate 2806 (segBright).
