APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday June 30, 2005 (MJD 53552) ---=== OBSERVING TEAM ===--- John Barentine Howard Brewington Support: French Leger ---=== OBSERVING PLAN ===--- Preparation for upcoming dark run ---=== OBSERVING SUMMARY ===--- To celebrate the last night of SDSS-I, we ran some basic pre-shake tasks in advance of the upcoming dark run. Completed checkout of the imager (except for flats), homed and relaxed M1. We can't establish a host session to M2 in order to home and relax the mirror. See Log. There was an alarm from the box on the south wall of the lower enclosure which houses switches for the extractor fans. We silenced the alarm but an indicator light is still on. ---=== OBSERVING LOG ===--- Even though a full shakedown wasn't required for the run, we felt it prudent to do some tests of basic aliveness in advance of the start of the run. During setup we heard an audible alarm from the box containing the switches for the extractor fans, and a red light was illuminated on the outside of the box. We silenced the alarm but the red light is still on. Imager ------ Run 5428 (Doghouse bias): All looks generally well, though we note that the bias level on u5 looks low on the scrolling displays. Examination of the FITS files on host shows that everything appears normal; we compared the bias vectors for this chip in skycat to those from MJD 53536 and they are very similar. checkBias reported no errors.

Left: 1.44 +/- 0.50 Right: 1.87 +/- 0.34 Mirrors ------- Homed and relaxed the primary with acceptable positioning errors in each case. However, we cannot establish a host session to the secondary (issuing the HOST TCC_SEC command results in nothing). We rebooted the migs without any luck. Also, we can't get mirror numbers for the log. Spectro ------- We checked the aliveness of the spectrographs by taking some biases and preCalibs along with a few guider frames. Also checked the mechanicals with a goSpecFocus to make sure the mirror would move as commanded. All looks fine. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5428 02:58Z 03:35Z 100 O 32.92 42.33 77 ignore 5429 03:38Z 03:53Z 100 O 43.04 46.88 40 ignore 5430 05:43Z 06:06Z 100 O 74.48 80.20 52 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 03:55 33185 0.0 bias ----- sequence 33186, plate 1703 ------- 04:20 33186 10.0 flat 04:23 33187 2.0 arc 04:31 33188 2.1 arc 04:34 33189 2.1 arc 04:54 33190 2.1 arc 04:57 33191 2.1 arc 06:07 33195 10.0 flat 06:09 33196 2.0 arc ---=== 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 03:14Z 70 26 6 221 (SW) 486 - 03:46Z 70 28 5 199 (SSW) 507 - 04:17Z 68 37 11 129 (SE) 633 - 04:50Z 67 38 13 135 (SE) 660 - 06:31Z 66 39 1 126 (SE) 669 - ---=== TELESCOPE STATUS ===--- Telescope parked at 121,30 with Cart 1 (Plate 1703) mounted Counterweights at 250 Spectro autofill reconnected No interlocks bypassed Dewar weights at 06:20Z Imager: 130lbs 22psi Spectro: 125lbs 25psi ---=== SOFTWARE USED ===--- IOP/SOP: v3_149_0 Watcher: v2_30_0 MCP: v5_26_0 TPM: tpm_v2_47_0 AstroDa: v14_47 TCC: TCC 2.7.2.1 August 6 2004 sdssProcedures: v2_02 SoS: v4_10_7 hoggPT: v1_6_9 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- ---=== PROBLEMS IN DETAIL ===---
