APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday May 11, 2006 (MJD 53867) ---=== OBSERVING TEAM ===--- Observer: Howard Brewington ET crew: Jian Ge, Scott Fleming ---=== OBSERVING PLAN ===--- ET Science! ---=== OBSERVING SUMMARY ===--- We had clouds for most of the night. However, conditions inmproved at 10:00Z, so we pulled the enclosure and got 1.5 exposures on plate 8029. Dust/hours for the night = ~25K The spectro dewar needs to be changed. ---=== OBSERVING LOG ===--- Afternoon: ----------- No problems found during the afternoon checkout. Night: ----------- 00:50Z Doors and louvers opened, fans on. 01:45Z Cart 08, Plate 8024 mounted. We had a great deal of clouds tonight, so we did not pull the enclosure at the normal time. We waited for better conditions. 02:16Z Dust = 2.3K, temp = 9.6, humidity = 34.2%, cloudCamera = 242. 04:16Z Dust = 2.3K, temp = 10.3, humidity = 36.4%, cloudCamera = 130. The sky is competely covered with thin clouds, which are reflecting lots of moon light. The only objects visible, in fact, are the moon and Jupiter. 06:16Z Dust = 2.7K, temp = 11.1, humidity = 34%, cloudCamera = 160. 08:07Z Dust = 2.4K, temp = 10.8, humidity = 38.9%, cloudCamera = 240. 09:50Z Mounted cart 05 because the sky started to clear. 10:00Z Pulled enclosure 10:15Z Cart 05, Plate 8029. An Fk5 was used to find the field. Seeing = 1" dust = 2.4K, temp = 9.8, and humidity = 47% at the start of this 50-minute exposure. 11:05Z Cart 05, Plate 8029. Since we had a few extra minutes of sky available, we decided to do one more (but shorter) exposure, which was about 20-minutes. Seeing = 1.1", dust = 2.5K, temp = 9.7, and humidity = 49.7% endNight finished and was happy ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 39150, plate -9999 ------- 23:55 39150 0.0 bias 23:57 39151 0.0 bias ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 21:52Z 62 22 3 157 (SSE) 2231 - 22:24Z 61 22 10 186 (S) 2507 - 22:56Z 61 22 6 183 (S) 2560 - 23:28Z 59 22 13 211 (SSW) 2598 - 23:59Z 60 22 12 196 (SSW) 2551 - 00:31Z 58 21 14 213 (SSW) 2744 - 01:03Z 54 21 6 191 (S) 2553 - 01:35Z 52 19 6 191 (S) 2841 - 02:07Z 49 21 5 152 (SSE) 2533 - 02:39Z 49 22 7 169 (S) 2416 - 03:12Z 50 22 8 186 (S) 2374 - 03:44Z 49 22 2 174 (S) 2405 - 04:16Z 51 25 6 176 (S) 2346 - 04:48Z 50 24 7 180 (S) 2356 - 05:20Z 50 24 6 181 (S) 2459 - 05:52Z 51 24 5 177 (S) 2797 - 06:25Z 49 24 6 178 (S) 2540 - 06:57Z 52 26 6 191 (S) 2626 - 07:29Z 52 27 8 188 (S) 2686 - 08:01Z 51 27 8 186 (S) 2399 - 08:33Z 51 26 13 200 (SSW) 2493 - 09:05Z 50 26 10 201 (SSW) 2416 - 09:39Z 49 26 9 201 (SSW) 2390 - 10:10Z 49 29 13 190 (S) 2480 - 10:42Z 48 30 9 193 (SSW) 2603 - 11:14Z 49 31 9 201 (SSW) 2579 - ---=== TELESCOPE STATUS ===--- 00:50Z Doors and louvers opened, fans on 10:00Z Enclosure off. 11:38Z Enclosure on, doors/louvers closed, fans off Telescope at 121,30,00 mount; cart 05 mounted LN2 connected and turned on.
