APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 1, 2004 (MJD 53006) ---=== OBSERVING TEAM ===--- Snow clearance: Craig Loomis LN2 shifters: Steve Bastian, Wendell Jordan Night: Dan Long, Pete Newman ---=== OBSERVING PLAN ===--- Shakeup while moon too bright then science. ---=== OBSERVING SUMMARY ===--- Weather kept us closed. Shake-up items that did not require sky completed, and Yea, The Red Monster is Reveale'd! ---=== OBSERVING LOG ===--- Afternoon check-out went without incident. The spectrograph image positions and focus were within tolerances. Clouds, high humidity and blowing snow kept us closed all night, but we were able to complete the shake-up items that did not require sky. Specifically, we: - Checked the changes to sdssProcedures were good, with an updated and expanded document on special plates, and an afternoon check list that includes the spectrograph focus. - Took and processed imager illuminated flats (using the imager FF lamps) and biases. checkBias, checkFlat, biasGen, biasCheck all completed with no errors reported. Graphs look good, U3 too. Frames copied to phoenix per procedures. We were unable to complete the following as we did not get on the sky: - Test the fix in SOP v3_125_0 for the new guider code to use a proper dark frame when multiple guider flats taken per plate. The current version (v3_124_0) is unchanged. - Jim's forward/backward scan donut sequence still not done. These items will be carried over to the Jan shakedown list. And we have positive identification of the latest incarnation of a Red Monster! It was the phone on the north fork. This was verified in spectro exposures reproducing the telescope position during observations of plate 1489 on MJD 52988. Frames 24512 and 24513 were taken in the enclosure with stop buttons off but the phone in use. Frame 24514 was taken with the same set-up except the phone was unplugged. There is a clear signal a few hundred Angstroms wide in the red frames that varies from ~20 counts/pixel to ~40 counts/pixel across the CCDs when the phone was plugged in, and is absent when it was unplugged. SoS would not reduce these frames, but perhaps David could use them (phoneCals?) as a tool to remove the Red Monster from at least the recent plates with this problem. Our memories have faded of what the originalRed Monster was like (before these phones were installed). In any case, the offending phone has been removed from the telescope. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4357 23:03Z 23:22Z 100 O 155.96 160.83 45 ignore doghouse bias 4358 05:19Z 05:40Z 100 O -109.75 -104.63 48 bias Enclosure, dark 4359 05:41Z 06:00Z 100 O -104.24 -99.49 46 calibration Imager FF lamps ---=== 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 24506, plate 1360 ------- 22:52 24506 0.0 bias ----- sequence 24507, plate -9999 ------- 23:17 24507 0.0 bias ----- sequence 24507, plate 1360 ------- 23:25 24508 10.0 flat Focus checks 23:28 24509 2.0 arc " 23:35 24510 2.1 arc " 23:38 24511 2.1 arc " 03:12 24512 1200.0 test Phone LEDs on 03:44 24513 1200.0 test Phone LEDs on 04:10 24514 1200.0 test Phone LEDs off ---=== 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 ===--- No tapes to ship - endNight run against the cloudy-night tapes. ---=== 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 22:30Z 31 29 14 239 (WSW) 45 - 23:01Z 32 29 21 236 (SW) 64 - 23:32Z 31 29 14 254 (WSW) 102 - 00:05Z 30 29 10 240 (WSW) 108 - 00:38Z 29 28 14 242 (WSW) 38 - 01:10Z 29 29 6 223 (SW) 44641 - 01:42Z 29 28 11 213 (SSW) 751 - 02:14Z 29 28 11 225 (SW) 49161 - 02:47Z 29 29 12 221 (SW) 3618 - 03:17Z 29 27 11 225 (SW) 89 - 03:47Z 29 27 13 243 (WSW) 69 - 04:19Z 29 28 10 254 (WSW) 70 - 04:51Z 30 27 9 199 (SSW) 125 - 05:23Z 30 29 12 265 (W) 151 - 05:55Z 30 30 10 274 (W) 10215 - 06:27Z 31 25 12 264 (W) 134 - 07:00Z 31 23 22 270 (W) 123 - 07:32Z 30 28 16 269 (W) 168 - 08:05Z 30 29 19 262 (W) 173 - 08:37Z 30 28 21 240 (WSW) 224 - 09:09Z 31 29 15 253 (WSW) 253 - 09:41Z 30 29 18 267 (W) 261 - 10:13Z 32 26 21 280 (W) 267 - 10:46Z 32 27 22 268 (W) 197 - ---=== TELESCOPE STATUS ===--- Enclosure on all night.
