APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 20, 2009 (MJD 54852) ---=== OBSERVING TEAM ===--- Elena Malanushenko Viktor Malanushenko Alaina Shelden (training) Steph Snedden (afternoon) ---=== OBSERVING PLAN ===--- 20 Jan 2009 54852.0 0.31 BOSS/SEGUE 10.8 hours ---=== OBSERVING SUMMARY ===--- The whole night was gorgeously photometric. :) Imager: Imaged 74S stripe at the beginning of the night lambda=153 to -153 including the ramp. Spectro: we observed three plates and two of them has been declared as done, the plates 3206 and 3211. ---=== OBSERVING LOG ===--- Afternoon: --------- Adjusted spectro focus to an estimated air temp of about 2C. No problems noted during afternoon checkout. Deleted MJDs 54825 - 54827 data from sdsshost2 / sdssfiles1. The disk space is now: /dev/sdb1 917G 832G 39G 96% /data sdssfiles1p:/data1/data 1.5T 821G 572G 59% /files Delayed ventilation because of high dust counts. Night: ----- 00:23Z Sunset 00:40Z - Opened enclosure 01:14Z Mounted imager Imaging 74 S stripe. 01:26Z Start run goDrift Run 7923. Focus was happy from frame 15 Skippy was happy from frame 12 01:42Z Start ramp, lambda=153 frame 36. Seeing was less than 1.6". 01:50Z Start science, lambda=155, frame 49, alt ~31.5. 01:51Z -18 deg evening twilight 02:12Z Seeing jumped to almost 2.5" and then settled back down to about 1.5" frames 79-84. Dimm did not show this jump. 03:22Z Another brief spike in seeing, which immediately came back to ~1.5" frames 193-196 04:11Z Seeing varied around 2.0" for frames 281-282, 295-297, 312-330, 345-361. This was for lambda=-170 to the end of drift. 05:10Z End science lambda=-155 frame 383 alt ~34 seeing ~1.6" 05:17Z End ramp lambda=-153 frame 396 seeing ~2.0" 05:21Z Bias on telescope Run 7924 05:25Z No other stripes available for imaging at this time.
