APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday July 1, 2008 (MJD 54649) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Steph Snedden Dan Oravetz (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, rain lightning with a couple of brief sucker holes. We did QE measurements on g6 and i4 The spectro dewar needs to be changed sometime during the day. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working properly. The Telescope Coolant Pump Circulation gauge is no longer reading zero. sdsshost2.apo.nmsu.edu % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 132G 2.9G 98% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 638G 233G 74% /data sdssfiles1:/data1/data 1.5T 631G 762G 46% /files Spectro focus set for ~13C (sp1) and ~12C (sp2). Cartridge 3 is mounted. Night: ----- 03:16Z - After waiting for lightning to move out of the area we set up for MSP calibrations. During the QE on g6, a sucker hole opened, but there were storms approaching and shortly after the hole opened, humidity went past closing conditions. The g6 images show several small round defects, one larger round darkish spot and a strange oval spot on the CCD. The spots are darker than the nearby illuminated CCD by about 4 percent. Jim wants us to do some goStares with the imager mounted and using the imager flat lamps to see how the spots look then. The details of the test request will go into the science plan. Photodiode voltage variations were within tolerance - they are detailed in the problems section at the end of the log.

The lightning moved off eventually, but it was too late to start another QE measurement anyway. 10:16Z - We shut down the MSP and telescope. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7590 00:23Z 01:02Z 100 O -4.61 5.05 79 ignore 7592 09:52Z 09:56Z 100 O 138.08 138.94 20 bias ---=== 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 ----- sequence 53878, plate -9999 ------- 00:26 53878 0.0 bias ----- sequence 53879, plate 2901 ------- 01:05 53879 10.0 flat 01:08 53880 2.0 arc 01:13 53881 3.0 arc 01:16 53882 2.0 arc ----- sequence 53883, plate -9999 ------- 01:28 53883 0.0 bias 01:30 53884 0.0 bias ----- sequence 53885, plate 2901 ------- 01:37 53885 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 ===--- ---=== 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 00:26Z 62 50 2 155 (SSE) 1921 - clouds 00:58Z 60 48 4 184 (S) 1996 - clouds 01:29Z 61 49 7 126 (SE) 2101 - clouds 02:03Z 57 50 9 88 (E) 2133 - clouds 02:35Z 55 49 12 52 (NE) 2166 - clouds 03:07Z 58 36 9 53 (NE) 714 - clouds 03:39Z 57 41 0 215 (SW) 1212 - clouds 04:11Z 57 44 5 174 (S) 1738 - partly cloudy 04:41Z 54 50 8 128 (SE) 3975 - ' 05:12Z 55 48 5 128 (SE) 3745 - ' 05:42Z 55 49 2 128 (SE) 3616 - ' 06:12Z 56 48 2 189 (S) 2800 - partly cloudy 06:42Z 57 46 5 234 (SW) 2652 - ' 07:12Z 55 46 9 0 (N) 2631 - cloudy 07:43Z 54 47 11 21 (NNE) 2274 - ' 08:14Z 53 49 13 35 (NE) 3170 - ' 08:45Z 52 50 4 0 (N) 3484 - ' 09:15Z 53 50 5 206 (SSW) 3792 - rain 09:46Z 51 50 7 179 (S) 3880 - ' 10:17Z 52 49 7 165 (SSE) 3790 - cloudy ---=== TELESCOPE STATUS ===--- Did not open or ventilate Status at: 10:17Z Telescope stowed at: 30,121,00 mount Instrument mounted: Cartridge 3 Counterweights at: 250 lbs LN2 autofill systems: Connected and turned on. 180L LN2 dewar scales: Spectro 88.5 lbs, 24 psi Imager 167 lbs, 19 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: v5_1_8 plate-mapper: v4_3_1 ---=== MIRROR NUMBERS ===--- PRIMARY: -------- Scale: 1.000000 MIGS TONIGHT NOMINAL Axial A 0.0210 0.0200 Axial B -0.0330 0.0000 Axial C -0.0230 -0.0230 Trans D -0.0200 0.0120 Lateral E 10.0584 10.0584 Lateral F 11.6332 11.6205 GALILS Commanded: 4600. -2000. 2650. -12450. -6500. -6550.
