APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday November 1, 2008 (MJD 54772) ---=== OBSERVING TEAM ===--- Elena Malanushenko (swing) Dmitry Bizyaev Audrey Simmons ---=== OBSERVING PLAN ===--- Science! 1 Nov 2008 54772.0 0.26 BOSS/SEGUE 10.4 hours ---=== OBSERVING SUMMARY ===--- Spectroscopy during partly cloudy skies: Cart 4, plate 3128 Cart 6, plate 3146 Cart 8, plate 3143 - finished Cart 7, plate 3114 Cart 1, plate 2962 (baotest) BOSS imaging during photometric skies: Stripe 77 S imaged from lambda 148 to -153, including ramps. Seeing averaged 1.6" at beginning; last half averaged 1.2". From lambda 152 (frames 51-52), there were very thin clouds seen on the cloud camera that might have effected the data (see log for details). ---=== OBSERVING LOG ===--- Afternoon: ========== All systems are checked and they work properly. Spectro collimation is adjusted for 10C. 23:25 ventilation Cart 4 is mounted. Night: ====== 00:17Z - Sunset. 00:20Z - Opened enclosure to partly cloudy skies. Force filled the spectrographs. 00:48Z - goToField cart 4, segue plate 3128. GSFOGTF. 01:06Z - Precals. 01:14Z - 25 min exposure. Seeing 1.0" 01:35Z - Twilight ends. 01:41Z - 30 min exposure. 02:15Z - Postcals. This plate is not done yet. 02:24Z - Mounted cart 6, segue plate 3146. GSFOGTF. 02:33Z - Precals. 02:40Z - 25 min exposure. Seeing 1.3" 03:08Z - 25 min exposure. 03:36Z - Postcals. This plate is not done yet. 03:45Z - Mounted cart 8, segue plate 3143. GSFOGTF. 03:54Z - Precals. 04:03Z - 30 min exposure. Seeing 1.1" No need for postcals. This plate has enough signal to be declared DONE. 04:39Z - Mounted cart 7, segue plate 3114. GSFOGTF. 04:45Z - Precals. 04:52Z - 20 min exposure. Seeing 1.2" No postcals needed. The clouds cleared and the seeing remained stable around 1.1-1.3" (according to the guider). We switched to BOSS imaging. 05:15Z - Mounted imager. scanStripe Stripe 77 S -startLambda 145. 05:34Z - goDrift 77 S, run #7787, tccSetFocus -280. Skippy happy from the beginning. Focus happy from frame 17. Seeing acceptable from beginning - 1.6" 05:43Z - Start ramp at lambda 148, frame 23. 05:51Z - Start science at lambda 150, frame 36. We saw thin clouds on the cloud camera that passed through the area that the telescope was pointing. This was at ~06:02Z and lasted about a minute (lambda 152, frames 51-52). The clouds were so small that they did not register on the sky standard deviation graph. They drifted at a very low altitude from the west to the south for a duration of ~45 minutes (near ~06:30Z (frame 105), there was a small bump seen on the cloud camera graph). We decided to stay on the field since we did not see any clouds on the satellite image, the seeing remained acceptable, and the light clouds seemed to be passing us by. If the clouds have disrupted the data, then we might be able to go back and reimage the stripe another night. Lambda 160, frame 105 - seeing spike to 2.3" (lasted 1 frame). 08:00Z - Daylight savings begins. 09:30Z - End science at lambda -155, frame 404. 09:39Z - End ramp at lambda -153, frame 418. Seeing 1.0-1.4" the last half of the run (lambda 173 to -153).

Some clouds came in. We decided to complete the imager bias while we wait to see if the clouds go away. 09:54Z - Imager bias with tbars UNLATCHED, run #7788, frames 8-44. 10:18Z - Clouds persisted. We decided to switch back to spectroscopy. Mounted cart 1, baotest plate 2962. 10:28Z - goToField. Used fk5 to find field. Guide stars are pretty faint, efficiency is low, some stars are not reading at all, and there is a wide range in seeing. The clouds cleared, but there are more closeby. 10:50Z - Precals. 11:00Z - 25 min exposure.
