APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday March 24, 2008 (MJD 54550) ---=== OBSERVING TEAM ===--- Howard Brewington (observer) Dan Oravetz (observer) Dmitry Bizyaev (dayshift) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We did spectroscopy the first part of the night until the combination of dust and humidity (in addition to the rising Moon) led us to close and opt for imager calibrations the rest of the night. Integrated dust count ~20,000 dust-hours with humidity between 40% and 50% and sometimes over 50%. Please check the mirrors. Spectroscopy ------------ Finished cartridge 9, 2961. Obtained 2 exposures on cartridge 6, 2394. MSP --- Completed g1 linearity. Completed z1 QE. ---=== OBSERVING LOG ===--- Afternoon: ---------- MT crate rebooted. Photo and Spectro crates are OK. HD cleaned of safely transferred old data. Spectro focus set for ~1C. 00:15Z - Began ventilation. Doors and louvers opened, fans on. 00:40Z - Cadtridge 9 mounted. Night: ------ 01:20Z - Enclosure off. 01:23Z - Sunset. Cartridge 9, 2961, baotest187 ***************************** 01:37Z - gotoField. We went right to a fk5 since the sky was still relatively bright and found it on the first attempt. Previous signal obtained: 54538: 54549: ----- ----- b1 r1 b2 r2 b1 r1 b2 r2 -- -- -- -- -- -- -- -- 0.6 0.2 1.3 2.6 0.5 0.7 0.3 0.4 1.6 1.1 3.2 2.7 0.5 1.0 0.2 0.3 1.6 1.6 3.4 2.6 2.5 1.8 4.7 3.1 02:12Z - Pre-Calibs. We had mostly yellow xsigma and wsigma values since the telescope and optics were still equilibrating. We moved both sp1 and sp2 +3000 steps, so spectro focus should now be adusted to ~4C. 02:25Z - Pre-Calibs. 02:32Z - Science. 1500s. (S/N)^2 = 4.3 2.7 7.2 5.2 02:59Z - Science. 1500s. 3.7 2.2 5.8 5.1 03:27Z - Science. 1667s. 4.8 3.2 7.7 7.1 03:58Z - Mid-Calibs. 04:04Z - Issued an `axis stop' since altitude was at 88.8 degrees and the azimuth and rotator started slewing. We got the cal's before the stop was issued. We waited until the telescope tracked through the zenith. 04:20Z - The telescope tracked through the zenith and the rotator and azimuth did their somersaults, so we went back to the field. 04:21Z - gotoField. Used a fk5 to re-acquire the field. 04:29Z - Pre-Calibs. 04:37Z - Science. 1800s.

Cartridge 6, 2394, segue133 *************************** 06:27Z - gotoField. Guide stars found on gotoField. 06:34Z - Pre-Calibs. 06:40Z - Science. 1500s.

The dust had been around 2500 since we began ventilating and the humidity had mostly been around 40%, but had spiked over 50% a few times. The Moon was also getting brighter/higher and as a result of these conditions we switched to imager calibrations. 08:00Z - Enclosure on, doors closed. 08:46Z - Began g1 linearity measurements. Run 7394. Frame 1 was the 1-frame bias. Linearity measurements are frames 2 - 20. 10:02Z - Began z1 QE measurements. Run 7394. Frames 21 - 57. 12:00Z - Shutdown MSP hardware. Stopped fans and closed louvers. 12:18Z - endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 7393 22:38Z 23:01Z 100 O -128.61 -122.82 47 ignore 7394 MSP g1 lin z1 QE 7395 12:01Z 12:06Z 100 O 72.66 73.95 21 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): y UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 51196, plate 2253 ------- 22:59 51196 10.0 flat 23:02 51197 2.0 arc 23:12 51198 3.0 arc 23:15 51199 3.0 arc ----- sequence 51200, plate -9999 ------- 00:21 51200 0.0 bias 00:40 51201 0.0 bias ----- sequence 51202, plate 2961 ------- 02:14 51202 10.0 flat 02:17 51203 2.0 arc 02:27 51204 10.0 flat 02:30 51205 2.0 arc 02:59 51206 1501.0 target 03:27 51207 1501.0 target ----- sequence 51208, plate 2961 ------- 03:58 51208 1667.0 target 04:00 51209 10.0 flat 04:03 51210 2.0 arc 04:32 51211 10.0 flat 04:34 51212 2.0 arc 05:09 51213 1802.0 target 05:42 51214 1800.0 target 06:15 51215 1800.0 target 06:18 51216 10.0 flat 06:21 51217 2.0 arc ----- sequence 51218, plate 2394 ------- 06:36 51218 10.0 flat 06:39 51219 2.0 arc 07:08 51220 1500.0 target 07:41 51221 1802.0 target 07:47 51222 10.0 flat 07:49 51223 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 02:33Z 9 2961 96.60 0.0016 69.57 0.0037 -96.70 0.0291 1.000000 04:44Z 9 2961 267.84 -0.0005 82.97 0.0011 92.41 0.0344 0.999860 06:45Z 6 2394 190.39 0.0035 63.09 0.0019 17.13 -0.0054 1.000140 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 02:33Z 9 2961 1.00000 0 1257 125 97 69.6 5.0 9 224 --- 1.0" 04:43Z 9 2961 0.99986 1383 2210 -50 268 83.0 5.7 12 231 --- 1.2" 06:45Z 6 2394 1.00014 -1383 -9 -10 190 63.1 5.6 13 258 --- 1.3" ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:55Z 46 3 12 268 (W) 2218 - mostly clear 23:28Z 45 11 12 267 (W) 2460 - mostly clear 23:58Z 46 12 4 245 (WSW) 2476 - mostly clear 00:29Z 47 13 10 259 (W) 2536 - clear 01:01Z 43 13 8 263 (W) 2660 - clear 01:21Z 41 13 8 254 (WSW) 2682 - clear 01:52Z 41 11 8 220 (SW) 2620 - clear 02:22Z 40 11 5 244 (WSW) 2496 - clear 02:52Z 39 11 4 265 (W) 2561 - clear 03:22Z 41 12 1 216 (SW) 2537 - clear 03:52Z 41 15 9 212 (SSW) 2503 - clear 04:23Z 42 10 13 226 (SW) 2227 - clear 04:54Z 42 12 12 234 (SW) 2324 - clear 05:24Z 39 23 17 210 (SSW) 2518 - clear 05:54Z 40 24 13 218 (SW) 2359 - clear 06:25Z 42 17 16 244 (WSW) 2281 - clear 06:56Z 42 19 12 256 (WSW) 2312 - clear 07:26Z 41 21 12 236 (SW) 2197 - clear 07:58Z 42 22 15 264 (W) 2154 - clear 08:28Z 41 27 10 250 (WSW) 2433 - clear 08:58Z 41 25 11 271 (W) 2268 - clear 09:29Z 42 23 15 270 (W) 2273 - clear 10:00Z 42 24 19 282 (WNW) 2127 - clear 10:31Z 41 24 14 272 (W) 2091 - clear 11:04Z 41 24 14 266 (W) 2124 - clear 11:36Z 41 25 16 270 (W) 2056 - clear 12:08Z 40 26 13 266 (W) 2081 - clear ---=== TELESCOPE STATUS ===--- 00:15Z - Began ventilation.

Problems: -------- Neon calib lamps didn't come all on when were checked in the daytime. Several attempts required to have two upper Ne lamps working (both top if telescope is in stove position). Once started working ok, they started turning on all times with no failure after that.
