APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 30, 2003 (MJD 52670) ---=== OBSERVING TEAM ===--- swing: Howard Brewington night: Dan Long Pete Newman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- After a two and a half hour delay due to clouds, and slowed by poor seeing at times, we completed five plates and just missed getting a sixth. Not quite up to last night's standard, but still a pretty good night. 04:13Z Cartridge 2 1205 20.6 24.0 20.6 22.6 Done 05:38Z Cartridge 3 1206 17.9 18.9 15.4 16.7 Done 06:56Z Cartridge 4 940 20.1 20.2 15.3 15.8 Done 08:11Z Cartridge 5 1190 19.7 14.0 19.4 17.3 Done 09:36Z Cartridge 6 1001 21.6 14.1 21.6 15.0 Done 11:12Z Cartridge 7 1018 19.1 13.2 18.8 13.8 ---=== OBSERVING LOG ===--- 23:30Z Doors open, Fans on 00:30Z Clouds move in. High and mid level clouds with some virga. 03:50Z Enclosure open after cloud delay 04:13Z Cartridge 2 1205 20.6 24.0 20.6 22.6 Done Guide stars on the slew Large scale change .034 Reasonable seeing averaging about 1.8", sometimes as good as 1.3", sometimes rising over 2.2" Done in three exposures ( 900, 600, 600 ) 05:38Z Cartridge 3 1206 17.9 18.9 15.4 16.7 Done Guide stars on cleared offsets Scale remains nearly 1.0003 Fiber 3 significantly away from focal plane. It shows a donut when all others are in focus. Seeing holding around 1.8" despite being at high elevation. Done in three 700 second exposures 06:56Z Cartridge 4 940 20.1 20.2 15.3 15.8 Done Guide stars on cleared offsets Seeing started out around 1.7", ballooned to 2.5", dropping to 1.6" in the last exposure. Done in three exposures ( 700, 700, 850 ) 08:11Z Cartridge 5 1190 19.7 14.0 19.4 17.3 Done Guide stars on what appears to be repeatable southern pointing offsets of 7 2 Seeing spending more time around 2.5" than below 2.0" Done in three exposures ( 750, 900, 1100 ) 09:36Z Cartridge 6 1001 21.6 14.1 21.6 15.0 Done Guide stars on slew Seeing varying between 2.0" and 3.5" Strong NE wind, 30 MPH met tower, 10 MPH pier. Seeing staying around 3.5" - really cutting into efficiency Only got (S/N)^2 3.6 in 1000s. That's just about enough of that! Settle down, right this minute! Admonishment didn't work. Seeing still poor. Only got 5.0 in 20 min Done in three longish exposures ( 1000, 1200, 1200 ) 11:12Z Cartridge 7 1018 19.1 13.2 18.8 13.8 One episode of the hanging instChange. PR iop/4542 updated. Needed FK5, offset 7 -10 from cleared offsets. Seeing slightly better, staying around 2.5" 12:10Z Cloud skirting low in NE up to about 20 degrees elevation Not quite done in three 1200 second exposures "Missed it by that much" ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3639 21:05Z 21:47Z 100 O 155.32 165.79 39 ignore ---=== 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 18943, plate -9999 ------- 20:58 18943 0.0 bias 21:38 18944 0.0 bias ----- sequence 18945, plate 810 ------- 22:36 18945 10.0 flat 22:48 18946 10.0 flat 22:55 18947 10.0 flat 23:04 18948 10.0 flat 23:09 18949 10.0 flat 23:12 18950 2.0 arc 23:17 18951 2.1 arc 23:20 18952 2.1 arc ----- sequence 18953, plate -9999 ------- 23:33 18953 0.0 bias ----- sequence 18954, plate 1205 ------- 20.6 24.0 20.6 22.6 Done 04:30 18954 10.0 flat 04:33 18955 2.0 arc 04:53 18956 900.1 target 05:06 18957 600.1 target 05:19 18958 600.1 target 05:27 18959 240.0 smear 05:30 18960 10.0 flat 05:32 18961 2.0 arc ----- sequence 18962, plate 1206 ------- 17.9 18.9 15.4 16.7 Done 05:51 18962 10.0 flat 05:54 18963 2.0 arc 06:12 18964 700.1 target 06:27 18965 700.1 target 06:42 18966 700.1 target 06:50 18967 240.0 smear ----- sequence 18968, plate 940 ------- 20.1 20.2 15.3 15.8 Done 07:07 18968 10.0 flat 07:10 18969 2.0 arc 07:27 18970 700.1 target 07:41 18971 700.1 target 07:59 18972 850.1 target 08:07 18973 240.0 smear ----- sequence 18974, plate 1190 ------- 19.7 14.0 19.4 17.3 Done 08:22 18974 10.0 flat 08:24 18975 2.0 arc 08:42 18976 750.1 target 09:00 18977 900.1 target 09:21 18978 1100.1 target 09:30 18979 240.0 smear ----- sequence 18980, plate 1001 ------- 21.6 14.1 21.6 15.0 Done 09:45 18980 10.0 flat 09:48 18981 2.0 arc 10:09 18982 1000.1 target 10:32 18983 1200.1 target 10:55 18984 1200.1 target 11:08 18985 240.0 smear ----- sequence 18986, plate 1018 ------- 19.1 13.2 18.8 13.8 11:25 18986 10.0 flat 11:27 18987 2.0 arc 11:55 18988 1200.1 target 12:18 18989 1200.1 target 12:41 18990 1200.1 target 12:49 18991 240.0 smear 12:53 18992 10.0 flat 12:55 18993 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 04:28Z 2 1205 82.69 0.0031 62.87 0.0027 247.66 0.0076 1.000340 06:05Z 3 1206 54.80 0.0046 81.31 0.0004 230.75 0.0256 1.000290 07:15Z 4 940 138.89 -0.0029 76.83 0.0008 -48.25 -0.0084 1.000070 08:20Z 5 1190 -31.31 0.0031 58.21 0.0015 153.93 -0.0199 1.000180 09:55Z 6 1001 -23.45 0.0036 62.29 0.0029 160.22 -0.0085 1.000100 11:33Z 7 1018 202.45 -0.0003 64.96 0.0038 34.01 -0.0114 1.000150 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL5981 Stays: JL5982 EndNight rejoiced. ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 04:28Z 2 1205 1.00034 -3356 -1753 -120 83 62.9 4.3 9 337 -
