APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday December 29, 2002 (MJD 52638) ---=== OBSERVING TEAM ===--- Swing: Steph Snedden Howard Brewington Night: Jurek Krzesinski Dan Long ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Lots of clouds. When thin enough we got data on two plates ( 1071, 1092 ). Light snow started falling after about 10:00Z. A PTVME failure killed sop session. Recovery was quick, but exposure in progress at the time was lost. ---=== OBSERVING LOG ===--- Today's plugging for some reason did not show up in the database in the "plan a night's observing" section. It was still showing last night's done plates. Since the plugMap files existed from today, we just added the maps to the database and then the observing section showed the current status. 00:40Z Cartridge 6 1092 Guidestars on slew. High clouds move in around 01:20Z. 02:17Z Jurek's sop session disappeared and the severs went with it. Almost certainly due to a ptvme glitch 2002-12-30 02:16:47Z sdsshost IOP 134862 dsc_E_shareLost Access to shared data area at 0x18000000 lost 2002-12-30 02:16:47Z sdsshost IOP 134862 dsc_E_readFail Read failed from PT icc40 CSB=0x00000000 2002-12-30 02:16:47Z sdsshost IOP 134862 dsc_E_readFail Read failed from rmt=0x18000000 cnt=0x0009ABE8 Jurek was able to simply restart sop ( no ptvme reset needed ). Unfortunately the exposure, which was in progress when his sop session disappeared, was lost. 02:40Z Cartridge 1 1071 Guidestars on slew. Efficiency on guider dropping below 30% at times now as clouds thicken. 03:50Z Clouds thick enough we close 08:40Z Clouds move out... Sucker hole large enough we get taken in. 08:50Z Cartridge 9 1061 Guide stars on slew despite acquiring at more than 80 degrees elevation. Clouds form quickly after we open. Can't even get set up. 09:05Z Lose guide stars due to clouds 09:10Z We go out to close back up. Once closed, we swap the imager dewar. GN2 bottle also low so it is changed as well. It started snowing around 10:30Z. We did not reopen. ---=== 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 ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 17659, plate -9999 ------- 23:48 17659 0.0 bias 23:54 17660 0.0 bias ----- sequence 17661, plate 1092 ------- 8.9 5.0 9.4 6.8 01:07 17661 10.0 flat 01:09 17662 2.0 arc 01:31 17663 900.1 target 01:49 17664 900.1 target ----- sequence 17665, plate -9999 ------- 02:21 17665 0.0 bias ----- sequence 17666, plate 1071 ------- 3.3 - 3.7 2.2 02:54 17666 10.0 flat 02:56 17667 2.0 arc 03:33 17668 1800.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:05Z 6 1092 -20.15 0.0032 55.61 0.0022 163.09 -0.0048 0.999910 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL5844 Stays: JL5845 endNight, easily pleased routine that it is, rejoiced. ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:06Z 6 1092 0.99991 888 2030 130 -20 55.6 -0.1 26 227 - 2.0 02:24Z 6 1092 0.99993 690 1866 100 -48 46.1 -0.7 22 212 - 2.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:38Z 32 11 27 233 (SW) 133 - Mostly Cloudy 23:09Z 33 12 20 234 (SW) 98 - Mostly Clear 23:39Z 32 10 27 226 (SW) 76 - Clear 00:09Z 31 10 21 232 (SW) 96 - Clear 00:40Z 32 7 25 233 (SW) 116 - Clear 01:10Z 31 8 22 229 (SW) 128 - Clear 01:44Z 31 10 23 221 (SW) 149 - Cirrus 02:20Z 30 11 20 228 (SW) 295 - Cirrus 02:51Z 30 11 27 222 (SW) 274 - Thick Cirrus 03:24Z 30 12 29 236 (SW) 395 - Variable Cirrus 03:54Z 30 11 32 233 (SW) 404 - Variable Cirrus 04:24Z 29 11 17 249 (WSW) 538 - Overcast 04:55Z 28 12 22 214 (SW) 331 - Overcast 05:27Z 28 11 21 252 (WSW) 212 - Overcast 05:57Z 28 10 19 249 (WSW) 199 - Overcast 06:27Z 26 11 22 237 (WSW) 178 - Overcast 06:58Z 27 10 29 246 (WSW) 187 - Overcast 07:30Z 26 11 18 262 (W) 173 - Overcast 08:02Z 25 13 17 266 (W) 199 - Overcast 08:34Z 25 14 17 276 (W) 236 - Mostly Cloudy 09:05Z 24 15 13 265 (W) 216 - Mostly Cloudy 09:37Z 24 16 21 274 (W) 256 - Cloudy 10:10Z 23 17 13 265 (W) 295 - Cloudy 10:42Z 23 17 14 285 (WNW) 304 - Flurries 11:15Z 21 18 17 266 (W) 501 - Lt Snow ---=== TELESCOPE STATUS ===--- 22:55Z Doors Open, Fans On 00:00Z Enclosure Open 03:50Z Enclosure Closed clouds 08:40Z Enclosure Open 09:10Z Enclosure Closed, Doors Closed, Fans Off Stowed at 30 deg alt, cartridge 9 installed.
