APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday June 18, 2008 (MJD 54636) ---=== OBSERVING TEAM ===--- Kaike Pan Dmitry Bizyaev Jon Brinkmann (support) ---=== OBSERVING PLAN ===--- Imager Calibration ---=== OBSERVING SUMMARY ===--- Imager calibration run, test of u-chip QE. QE u 1 done. Images need to be checked asap to understand if the calibrating diod works ok now. Sky is cloudy, by the way. Rain sensor got alarms but no actually noticeable rain was seen. sp1 red CCD is pretty warm, -82 or even -81, should be -90. Force fills of primary and secondary dewars do not help much. We informed French. ---=== OBSERVING LOG ===--- Evening: -------- Systems checked up Imager set up for calibrations Night: ------ The data pool was full. Jon turned the pool disk on. We restarted the teamster. Also the watcher showed errors on id3 and id6 because of lack of log files (probably connected to the previous problem). Photo crates rebooted. Temperature of CCD 04 showed up warm. We checked temperature of red sp1 and got -82C measured against -90C (all other are ok). sp1> cc 4 tcheck CAMERA 4 LN2 TEMP NOMINAL 77 K MEASURED 94 K CCD TEMP DAC SET AT 115 = -0.52 V = -90 C MEASURED -82 C We force filled sp1 and main spectro LN2 just in a case. We reported to French and filled secondary dewar again. French said may be camera pumping will be required sooner than summer shutdown. -- Imager set up for calibrations 08:43Z run 7560 fr. 1 - imager bias 08:48Z run 7560 - QE u 1, frames 2 - 34 -- endNight rejoiced ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 0 02:08Z 02:08Z 100 O 9.00 9.00 -1 ignore 7559 02:21Z 02:43Z 100 O 12.07 17.64 51 ignore 7561 05:56Z 06:13Z 100 O 66.03 70.25 42 ignore 0 02:08Z 02:08Z 100 O 9.00 9.00 -1 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== 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 01:47Z 71 33 7 193 (SSW) 2845 - cloudy 02:20Z 69 33 13 221 (SW) 3085 - '' 02:53Z 69 36 13 157 (SSE) 4214 - '' 03:25Z 69 35 12 179 (S) 4326 - '' 03:57Z 68 36 17 188 (S) 4943 - '' 04:29Z 67 38 14 186 (S) 4884 - '' 05:01Z 62 41 14 131 (SE) 3562 - '' 05:33Z 62 41 17 157 (SSE) 3242 - 06:06Z 62 40 14 145 (SE) 3019 - ---=== TELESCOPE STATUS ===--- Status at: 06:10Z Telescope stowed at: 30,121,00 mount Instrument mounted: Cartridge 5 Counterweights at: 254 lbs LN2 autofill systems: Connected and turned on. 180L LN2 dewar scales: Spectro 174 lbs, 21.5 psi Imager 161 lbs, 16.3 psi ---=== SOFTWARE USED ===--- IOP/SOP: v4_38_0 Watcher: v2_36_0 MCP: v6_4_0 TPM: tpm_v3_5_0 AstroDa: v15_13_1 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_42 SoS: plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- ---=== PROBLEMS IN DETAIL ===--- md1: dsc W monInternal Monitor task internal problem: Monitor log not initialized (dsc_W_monInternal Monitor task internal problem: Monitor log not initialized : 2008-06-19 02:18:48Z ) --- sp1 red CCD is pretty warm, -82 or even -81, should be -90.
