APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday February 11, 2008 (MJD 54508) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Elena Malanushenko Shannon Watters (afternoon) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The weather was not cooperative, clouds and bad seeing. We finished three plates 2940, 2652, and 2756, and obtained some signal on three other plates 2549,2877,2150. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working. Spectro focus set to ~3.5C. Night: ----- Clear, Moon is until 5:50, T=4.9C and foc=75. Cart 1, plate 2940, segue. Used FK5 to find the guider stars. 1:37 precalib - early calibration to check if we need to adjust anything. Everything is ok. 1:47 preCalib We need to wait a little as start time for this plate is 2:34, we have started 20 min before this time. 2:16 science 900 2:34 science 900 Postcalib is required by sos, and we did this. 2:51 postCalib During the science exposures we need to keep negative scale adjustments based on results of sop guider date window. 02:58 science 900 03:16 science 1200 03:39 science 1200 We obtained sufficient signal to declare this plate as DONE as b2 (s/n)^2=35, but we have extra time for one more exposure before the next cartridge starts. 04:02Z science 1200 04:25 postCalibs This plate is DONE. Cart 2, Plate 2549. Segue Faint with priority 4. The sky is not photometric anymore and some clouds are walking around. Used FK5 to find the guider stars. 4:50 preCalib 4:58 science 1200, the clouds are thick and the efficiency is very low, we aborted the exposure at 5:06. Wait for weather improvement. 05:24 science 1200 05:47 science 1200, we paused this exposure and aborted this erxposure also because of clouds. 5:55 science 1200 6:18 science 1200->1500 6:46 postCalib We obtained good signal on this plate even in cloudy condition (16.7) but need to continue observations. Cart 3. plate 2877. Segue Faint. Used FK5 to find the guider stars. 07:04 preCalib 07:11 science 1200 07:34 science 1200->1500 08:02 science 1500 08:30 postcalib Obtained (s/n)^2~21, need to continue observations. Cart. 4 Plate 2652, chunk FSonGTF 08:47 preCalib 08:53 science 900->1200 09:16 science 1200 The seeing is getting bad up to 2.5-3.0", efficiency goes down. 09:39 science 1200 10:02 science 900 This plate is DONE with (s/n)^2=16.0 Cart. 5 plate 2756, chunk FSonGTF 10:30 preCalib 10:36 science 900 10:54 science 900-> 1200 11:42 science 1200-> 900 postcalib This plate is DONE Cart 8, plate 2150, chunk Guider stopped working properly. Error: GMAKEHIST: Flat exposure is too faint. Counts in fibers must be > 500 We stopped and Started Mon, goToField again and it fixed the problem.
