APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday February 11, 2004 (MJD 53047) ---=== OBSERVING TEAM ===--- swing: Dan Long night: Atsuko Nitta Steph Snedden John Barentine ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Science. Oblique scan done. Two plates declared done, useable signal on two others. Some clouds and high humidity as well. ---=== OBSERVING LOG ===--- Afternoon: ---------- The west door would not go down, only up. It looks like the safety bumper may be stuck in the compressed state. M2 galil was complaining of a fault on one or more motor amplifiers showing a fault. The galil was power cycled and the mirror homed. It worked fine after that. Note: About a half-hour after this, we saw an m2 mig communications fault in the Watcher. We do not know if this is all related to work that was done on the actuators and controller recently. French was notified, but no PR was filed. The rotator aborted on the test slew. The current limit was exceeded. Resetting the amplifier down stairs cleared the error. Subsequent test slews were OK. Motor current values were running between 5000 and 7000. Spectro focus checked and needed no focus. 23:30Z Doors Open, Fans On. 00:45Z Enclosure Open. Night: ------ We opened at sunset to partly cloudy skies. Spectroscopy. Cartridge 6, plate 1733 FK5 needed to find field. Plate finished in a total exposure of 2700 s. 03:08Z - We decide that there is a good chance that clouds will stay away for a few hours and switch to imaging. We do a short drift on stripe 26, N to verify Skippy is good, then go off to the oblique scan. 03:34Z - Oblique scan - Run 4448 03:36Z - Start of oblique scan. 03:38Z - Frame 11, 2 degree ramp begins 03:46Z - Frame 24, start of oblique calibration. Naturally, as we started imaging, the seeing deteriorated. It was still acceptable, though. Also, as we drifted, we saw clouds appear on the horizon. Of course. By frame 30, the seeing had improved and the clouds receeded. Immediately after the scan stopped, clouds started forming orographically on top of us! Atsuko made a good gamble that paid off. The oblique scan was successfully completed. 04:27Z - Frame 92, end of oblique calibration. 04:35Z - Frame 108, end of scan. 04:49Z - Back to spectroscopy with cartridge 7, plate 1361. After slewing to the field and finding an FK5, the clouds became too thick to work. On slewing to the field, the first gflat exposure prompted an error message saying that it was too faint. The entire error message is in the problems section. 05:16Z - After waiting a bit, we closed the enclosure, but left the doors open and cone fans on. 07:04Z - Opened back up for spectroscopy Cartridge 7, plate 1361. The azimuth brake was sluggish and took about five tries before it cleared. Guide stars on goToField (the offsets were already in from before). This plate was declared done with a total exposure of 2900 s. 08:34Z - Cartridge 8, plate 1303. We saw the faint flat error again on the guider flat. WARNING: When this error happens, the flat field petals stay closed and the lamps are left on. After this happened we were unable to guide. The error that we got is in the problems section. Another goToField -gflat was issued. We started this plate late in its time range and couldn't finish, but got good signal in 1800s total. 09:51Z - Cartridge 1, plate 1362. We barely finished one 900 s exposure on this plate before the humidity skyrocketed. We ran down to close. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4445 22:26Z 23:04Z 100 O -173.04 -163.30 73 ignore 4446 03:10Z 03:22Z 100 O -101.60 -98.66 34 ignore 4447 03:23Z 03:33Z 26 N -62.16 -59.80 30 ignore skippy setup 4448 03:36Z 04:37Z 100 O -95.29 -79.88 116 calibration oblique scan 4449 10:46Z 11:06Z 100 O 12.62 17.67 48 bias ---=== IMAGING RUN DETAILS ===--- See the main log. ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- 4447 12 2 59 -7.300 0.116 -5.100 0.104 -0.00493 111 59 4447 18 4 143 -7.600 0.106 -5.300 0.140 -0.00458 111 59 ---=== 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 24974, plate -9999 ------- See SoS Archive 22:30 24974 0.0 bias ----- sequence 24975, plate 1314 ------- 22:59 24975 10.0 flat 23:02 24976 2.1 arc 23:04 24977 2.1 arc ----- sequence 24978, plate 1733 ------- 00:50 24978 0.0 bias ----- sequence 24979, plate 1733 ------- 01:53 24980 10.0 flat 01:55 24981 2.0 arc 02:15 24982 900.1 target 02:33 24983 900.1 target 02:52 24984 900.1 target ----- sequence 24985, plate -9999 ------- 05:55 24985 0.0 bias ----- sequence 24986, plate 1361 ------- 07:29 24986 10.0 flat 07:32 24987 2.0 arc 07:53 24988 900.1 target 08:12 24989 900.1 target 08:33 24990 1100.1 target ----- sequence 24991, plate 1303 ------- 09:17 24991 900.1 target 09:35 24992 900.1 target 09:38 24993 10.0 flat 09:41 24994 2.0 arc ----- sequence 24995, plate 1362 ------- 10:09 24995 10.0 flat 10:12 24996 2.0 arc 10:33 24997 900.1 target ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 01:44Z 6 1733 112.88 0.0026 49.35 0.0008 -97.74 -0.0196 1.000300 07:46Z 7 1361 148.28 -0.0084 78.45 0.0018 -36.74 -0.0111 1.000080 09:19Z 8 1303 -59.74 0.0064 51.74 0.0032 132.54 -0.0065 1.000080 10:48Z 1 1362 121.00 0.0014 29.82 0.0067 0.00 -0.0084 1.000040 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL7211 JL7212 JL7213 JL7214 JL7215 JL7216 JL7226 Stays: JL7217 JL7218 JL7219 JL7220 JL7221 JL7222 JL7227 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 01:44Z 6 1733 1.00030 -2961 -918 350 113 49.3 -2.7 15 202 - 1.2 07:46Z 7 1361 1.00008 -790 716 250 148 78.4 -3.7 6 256 - 1.3 09:19Z 8 1303 1.00008 -790 771 250 -60 51.7 -4.3 12 202 - 1.5 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:16Z 29 15 14 255 (WSW) -9999 - Mostly Cloudy 22:47Z 27 13 5 280 (W) -9999 - Mostly Cloudy 23:20Z 34 18 10 273 (W) -9999 - Partly Cloudy 23:52Z 31 17 11 257 (WSW) -9999 - Partly Cloudy 00:24Z 28 15 12 258 (WSW) -9999 - Partly Cloudy 01:16Z 27 15 12 209 (SSW) -9999 - " 01:49Z 27 14 16 218 (SW) -9999 - " 02:21Z 27 12 17 209 (SSW) -9999 - " 02:53Z 25 13 18 203 (SSW) -9999 - " 03:25Z 25 10 20 218 (SW) -9999 - Mostly Clear 03:57Z 25 8 18 225 (SW) -9999 - " 04:30Z 25 7 17 238 (WSW) -9999 - " 05:02Z 25 7 13 248 (WSW) -9999 - Mostly Cloudy 05:34Z 26 7 14 243 (WSW) -9999 - " 06:05Z 26 6 13 250 (WSW) -9999 - " 06:36Z 25 6 13 247 (WSW) -9999 - " 07:07Z 24 7 8 226 (SW) -9999 - Mostly Clear 07:37Z 25 6 8 263 (W) -9999 - " 08:09Z 25 6 10 263 (W) -9999 - " 08:39Z 23 7 10 232 (SW) -9999 - " 09:09Z 24 8 11 208 (SSW) -9999 - " 09:40Z 24 8 11 187 (S) -9999 - " 10:12Z 24 8 14 211 (SSW) -9999 - " 10:42Z 16 11 5 82 (E) -9999 - " 11:14Z 16 12 2 130 (SE) -9999 - " 11:44Z 17 11 7 133 (SE) -9999 - " 12:15Z 16 10 10 186 (S) -9999 - " ---=== TELESCOPE STATUS ===--- 23:30Z - Fans & blowers on, doors open. 00:45Z - Opened enclosure. 05:16Z - Closed enclosure.
