APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday December 9, 2008 (MJD 54810) ---=== OBSERVING TEAM ===--- Dan Oravetz Steph Snedden (swing) Nathan DeLee (UF) Jiang Peng (UF) ---=== OBSERVING PLAN ===--- MARVELS science ---=== OBSERVING SUMMARY ===--- Blowing snow and high humidity kept us closed tonight. ---=== OBSERVING LOG ===--- Afternoon: --------- No afternoon imager bias, since Connie is still using ad1. Spectrograph focus was left unchanged (see after the problems section). No problems noted during afternoon checkout, except for large amounts of blowing snow. Plus, it is COLD with the wind chill. Data from MJD 54771 was removed from local disks. The disk space is now: /dev/sdb1 917G 813G 58G 94% /data sdssfiles1p:/data1/data 1.5T 890G 503G 64% /files Telescope ventilation was not started - high humidity. Night: ----- We checked the weather conditions at the enclosure throughout the night. Blowing snow persisted throughout the night and we also dealt with periods of high humidity. 12:00Z - The humidity was getting worse and blowing snow was still around. We called it. endNight complained about untransferred gangs in the pool for run 7852. The errors appear to be due to the work being done with ad1. I proceeded with endNight and it rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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 UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 57184, plate -9999 ------- 22:33 57184 0.0 bias ----- sequence 57185, plate -9999 ------- 22:53 57185 0.0 bias ----- sequence 57186, plate 3154 ------- 23:01 57186 10.0 flat 23:03 57187 2.0 arc 23:16 57188 3.0 arc 23:19 57189 3.0 arc ----- sequence 57190, plate -9999 ------- 00:15 57190 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 21:18Z 16 14 23 68 (ENE) 97 - 21:50Z 16 14 31 64 (ENE) 170 - 22:23Z 16 14 38 69 (ENE) 221 - 23:02Z 16 13 25 56 (NE) 183 - 23:35Z 15 12 28 73 (ENE) 116 - 00:07Z 14 12 19 71 (ENE) 122 - 00:31Z 13 11 34 68 (ENE) 125 - 01:03Z 13 11 21 58 (ENE) 172 - 01:35Z 14 11 29 70 (ENE) 151 - 02:07Z 15 11 33 59 (ENE) 131 - 02:39Z 14 10 26 59 (ENE) 106 - 03:11Z 14 9 3 173 (S) 113 - 03:44Z 15 7 30 58 (ENE) 163 - 04:16Z 15 7 20 37 (NE) 229 - 04:48Z 16 7 15 33 (NNE) 140 - 05:20Z 17 8 19 54 (NE) 116 - 05:52Z 18 9 17 46 (NE) 119 - 06:24Z 17 10 14 31 (NNE) 136 - 06:56Z 16 8 15 27 (NNE) 973 - 07:29Z 16 9 13 20 (NNE) 118 - 08:01Z 17 10 13 4 (N) 239 - 08:33Z 17 11 17 21 (NNE) 172 - 09:05Z 18 14 20 11 (N) 141 - 09:37Z 18 14 10 37 (NE) 241 - 10:09Z 17 14 16 24 (NNE) 381 - 10:41Z 17 15 16 13 (NNE) 183 - 11:14Z 16 15 15 18 (NNE) 186 - 11:46Z 16 16 9 16 (NNE) 210 - ---=== TELESCOPE STATUS ===--- We never opened or ventilated because of uncooperative weather.

I decided to leave the spectrograph focus alone, since I don't see much of a temperature effect. sp1> Coll_motor_A -4168 01P-0000004168 Coll_motor_B -4173 02P-0000004173 Coll_motor_C -4165 01P-0000004165 Coll_motor_A_status 132 01S0132 Coll_motor_B_status 132 02S0132 Coll_motor_C_status 133 01S0133 Requested_exp.time 0 Exp_time_left 0 Last_exp.time 3 Last_open_transit.time 710 Last_close_transit.time 545 Humid_Hartmann 30.7 0xFD23 Humid_Cen_Optics 11.2 0xFE25 Temp_Median 4.8 Temp_Hartmann_Top 3.7 (0xFF65) Temp_Red_Cam_Bot 4.4 (0xFF46) Temp_Red_Cam_Top 5.1 (0xFF2A) Temp_Blue_Cam_Bot 4.8 (0xFF38) Temp_Blue_Cam_Top 4.8 (0xFF35) sp2> Coll_motor_A -2372 01P-0000002372 Coll_motor_B -2431 02P-0000002431 Coll_motor_C -2377 01P-0000002377 Coll_motor_A_status 133 01S0133 Coll_motor_B_status 132 02S0132 Coll_motor_C_status 133 01S0133 Requested_exp.time 0 Exp_time_left 0 Last_exp.time 3 Last_open_transit.time 730 Last_close_transit.time 655 Humid_Hartmann -24.9 0x4 Humid_Cen_Optics 11.2 0xFE24 Temp_Median 2.6 Temp_Hartmann_Top 3.0 (0xFF84) Temp_Red_Cam_Bot 3.1 (0xFF80) Temp_Red_Cam_Top 2.5 (0xFF98) Temp_Blue_Cam_Bot 2.6 (0xFF94) Temp_Blue_Cam_Top 3.0 (0xFF84) Daily spectro bias check: ------------------------- Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00057185.fit -5.8 -3.6 -2.5 1.9 7.4 8.5 10.1 sdR-b2-00057185.fit -8.0 -6.5 -4.2 0.8 7.1 9.5 10.9 sdR-r1-00057185.fit -7.3 -5.3 -4.0 1.4 6.7 8.0 10.2 sdR-r2-00057185.fit -7.9 -6.3 -4.7 1.1 6.8 8.4 10.0
