APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 24, 2006 (MJD 53760) ---=== OBSERVING TEAM ===--- Swing: K. Pan Night: H. Brewington, J. Barentine Support: Russell Owen (phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- What are these icy, fluffly, flaky things flying about in my flashlight beam outside. Could it be? Snow? Yes! The precipitation-starved Sacramento Mountains got frosted tonight with ~1 inch of fresh snow as of 11:00Z. At that time it was still coming down so needless to say, we got nothing tonight. The lower enclosure heater was turned on at the end of the night. ---=== OBSERVING LOG ===--- Afternoon: I was not be able to run telrun on tcc while a ping showed tcc alive. R. Owen was called and found that tcc was set to a single user, and he set it back to normal. postcalib exposures gave the following message (at the moment, telescope was not tracking), but frames went through SOS and turned out okay. 2006-01-24 22:59:51Z: NaN value for SPA in spectro fits header 2006-01-24 22:59:51Z: NaN value for IPA in spectro fits header 2006-01-24 22:59:51Z: NaN value for IPARATE in spectro fits header 2006-01-24 22:59:51Z: NaN value for AZ in spectro fits header 2006-01-24 22:59:51Z: NaN value for ALT in spectro fits header GN2 pressure was found below 500 psi, and was replaced by Norman and French. MIGS of the secondary were quite different from their nominal numbers, the secondary was home/relaxed. Then their MIGS are normal. Spectrograph focus checked, and adusted the best focus at about 1 C. As usual, details in problem section. 23:00 Louvers Open, Fans On. 00:00 doors open. Night ----- Clouds. When I (JCB) tried to take the log from Kaike, I could not make it editable in my logTool. The "Editable" word was blacked in, but the button couldn't be pressed. I was logged into sdsshost2 as myself at the time, from where I started logTool. I logged out, logged back in as observer, and started up logTool again. This time I could make the log editable. 07:51Z Rain sensor tripped and.... it's.... SNOWING!!!!!!! 10:55Z Snowing harder now. No sign it's going to let up anytime soon. We put the 2.5m away for the night. We turned on the heater in the lower enclosure to keep things toasty. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5992 22:59Z 23:16Z 100 O -181.86 -177.72 42 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 ===--- Summary Checked (y/n): y QA Procedures Done (y/n): n/a UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 36700, plate -9999 ------- 22:37 36700 0.0 bias ----- sequence 36701, plate 2379 ------- 23:00 36701 10.0 flat 23:02 36702 2.0 arc 23:06 36703 2.1 arc 23:09 36704 2.1 arc 23:26 36705 2.1 arc 23:29 36706 2.1 arc 23:41 36707 2.1 arc 23:43 36708 2.1 arc 00:23 36709 0.0 bias ----- sequence 36710, plate -9999 ------- 00:29 36710 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 ------------------------------------------------------------------------------ 23:33Z unknown 1.00000 198 1463 0 121 30.1 3.9 8 93 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:19Z 43 7 6 198 (SSW) 965 - MstlyCldy 22:49Z 41 3 7 180 (S) 1017 - MstlyCldy 23:23Z 40 4 9 120 (ESE) 1074 - Overcast 23:53Z 37 -1 10 87 (E) 822 - Overcast 00:23Z 35 -3 18 74 (ENE) 711 - Overcast 00:56Z 33 -4 24 75 (ENE) 664 - Overcast 07:49Z 32 17 15 132 (SE) 1628 - Overcast 08:20Z 30 27 19 131 (SE) 1208 - Overcast 08:50Z 32 22 21 126 (SE) 1384 - Overcast 09:20Z 29 24 20 125 (SE) 1647 - Overcast 09:50Z 29 24 14 110 (ESE) 1841 - Overcast 10:20Z 28 26 12 109 (ESE) 1449 - Overcast 10:54Z 28 27 21 113 (ESE) 996 - Overcast ---=== TELESCOPE STATUS ===--- 23:00S Fans on and louvers open. 00:00Z doors open. 07:35Z Doors closed, fans off Telescope parked at 121,30 with Cart 1 (Plate 2379) mounted Counterweights at 250 Spectro autofill reconnected No interlocks bypassed Dewar weights at 10:50Z Imager: 153lbs 22lbs Spectro: 281lbs 22lbs ---=== SOFTWARE USED ===--- IOP/SOP: v4_12_0 Watcher: v2_31_0 MCP: v5_26_2 TPM: tpm_v3_3_0 AstroDa: v15_10 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_09 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A -5.8410 -5.8440 Axial B -5.6850 -5.6770 Axial C 0.9300 0.9420 Trans D -10.0010 -9.9940 Lateral E 10.3759 10.3759 Lateral F 11.9507 11.9380 GALILS Commanded: 4700. -2450. 3000. -7800. 3300. 3000.
