APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday November 19, 2004 (MJD 53329) ---=== OBSERVING TEAM ===--- Jurek Krzesinski Howard Brewington Mike Harvanek (swing) Visitor: Steve Kent (FNAL) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We tried to observe one plate at the beginning of the night, but with clouds and bright moon we failed to get any useful S/N. The rest of the night we were closed due to high humidity or/and clouds. DIM: An attempt was made to test dimm tonight. Shortly after the telescope was powered up (30 seconds?), it started slewing toward the ground on it's own. See the problem section fo details. Today sop dumped core again (yesterday it did the same while opening the sop session)- see the problem section for the error message. BTW - if one wants to loo at the core file from such event it's in Jurek's home directry on host. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro collimation was adjusted. Details are in the Problems section. All 3 axes began the checkout with fiducial crossing corrections that were too large to correct. The requested ALT and AZ corrections were around 700; the ROT correction was around 800000. Subsequent readings on ALT and ROT axes were correctable but it was necessary to force an AZ fiducial reading to get that axis to correct. Upon startup, sop dumped core. The error message is in the Problems section. iop was setup again, sop was started again and it appeared to work normally. Nothing else to report. Night: ------ 01:08Z Cart 8 plt 2040 on the telescope. Stars on slew with offsets from the previous nights. The guider frame didn't arrive error message shwoed while we were in the middle of the focus loop. The focus loop had to be restarted. Clouds and bright moon made our first exposure (25 minutes) useless. After the second exposure, we took another calibration frame but the exposure appeared to be of low S/N as the previous one. Both lexposures were declared bad. 03:43Z Due to high humidity we decided to put enclosure over the telescope. The exposure we just started was aborded. The humidity was jumping up and down since then and most of the time we were covered with clouds. 11:50Z endNight run on cloudy tapes. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4970 22:35Z 22:49Z 100 O 107.21 110.91 39 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 29490, plate -9999 ------- 22:35 29490 0.0 bias ----- sequence 29491, plate 1905 ------- 23:19 29491 10.0 flat collimation 23:22 29492 2.0 arc collimation 23:25 29493 2.1 arc collimation 23:28 29494 2.1 arc collimation 23:44 29495 2.1 arc collimation 23:47 29496 2.1 arc collimation ----- sequence 29497, plate -9999 ------- 00:00 29497 0.0 bias 00:03 29498 0.0 bias 00:10 29499 0.0 bias ----- sequence 29500, plate 2040 ------- 01:22 29500 10.0 flat 01:25 29501 2.0 arc 02:22 29502 1500.1 target bad 03:17 29503 1500.1 target bad 03:22 29504 10.0 flat 03:24 29505 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 none Stays: JL none ---=== 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 22:22Z 37 22 3 295 (WNW) 117 - 22:54Z 37 29 10 303 (WNW) 217 - 23:26Z 35 29 9 308 (NW) 222 - partly cloudy, humid 23:58Z 34 32 3 343 (NNW) 366 - 00:27Z 33 27 2 351 (NNW) 364 - 00:59Z 34 26 3 10 (N) 179 - 01:30Z 33 27 6 5 (N) 206 - 02:02Z 33 28 3 333 (NNW) 213 - 02:35Z 34 27 4 282 (WNW) 164 - 03:08Z 34 26 3 276 (W) 124 - 03:40Z 33 28 1 214 (SW) 151 - 04:13Z 32 28 6 68 (ENE) 222 - 04:45Z 34 21 7 65 (ENE) 164 - 05:17Z 37 11 0 306 (NW) 58 - 05:49Z 36 12 0 277 (W) 136 - 06:22Z 33 26 2 202 (SSW) 212 - 06:54Z 32 24 0 101 (E) 225 - 07:26Z 34 19 1 47 (NE) 334 - 07:58Z 32 29 2 226 (SW) 300 - 08:31Z 31 29 1 242 (WSW) 285 - 09:03Z 33 24 4 264 (W) 212 - 09:35Z 33 24 8 269 (W) 158 - 10:07Z 32 26 7 274 (W) 223 - 10:40Z 32 27 6 260 (W) 230 - 11:12Z 33 28 7 269 (W) 305 - 11:44Z 32 28 10 240 (WSW) 318 - ---=== TELESCOPE STATUS ===--- 00:30Z Doors opened, fans on. 00:40Z Telescope opened, dewars refilled. 03:50Z Telescope closed due to high humidity.

Shortly after the telescope was powered up (30 seconds?), it started slewing toward the ground. The telescope was powered down and then powered up again. It headed towards the ground again. A third try yielded the same result. Steph Snedden and Jon Brinkmann were notified. It was decided to just leave the telescope powered down. When stowing the telescope, it sounded like the camera shutter was opening and closing. Steph was notified and it was decided to power down the camera as well. The camera was at ambient temperature before it was powered down. The telescope is in stow position and powered down. On a related note, the SBIG key that used to be in the dimm tub is no longer there. The SBIG key that was in the upper right drawer of the toolbox in the upper enclosure was used to open the camera box and is now somewhere at the bottom of the pier. I (Mike) dropped it through the grate while opening the camera box. I looked for it for half an hour but could not find it. Perhaps daylight will improve my chances of finding it.
