APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday October 23, 2005 (MJD 53667) ---=== OBSERVING TEAM ===--- Swing: Steph Snedden Olena Malanushenko Viktor Malanushenko Night: John Barentine Mike Harvanek Support: Eric Neilsen (phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Ah, perhaps the most frustrating kind of night at APO: a clear sky and a closed telescope. The humidity hovered too close to the closure limit for comfort all night long and we never dared bringing on a fog bank by opening. (Said fog bank arrived, as if on cue, just as we put away the telescope for the night.) We did, however, declare IOP version 4_6_0a current after resolving lingering shake issues from last night. ---=== OBSERVING LOG ===--- Afternoon --------- We are Howardless today, so Steph used today's checkout as a training exercise for Olena and Viktor, with assistance from Mike and I. Skies were clear in the afternoon but weather threatened: the eastern half of NM had been under low cloud all day long, with a cold front advancing in from west Texas. We mounted the imager in the enclosure around sunset but did not open, expecting humidity to rise. Night ----- After dusk the humidity settled around 75% (split was slightly above 3 deg C) so we decided not to open; the forecast called for mostly cloudy overnight. There were problems tonight with the night log similar to what the observers experienced last night. On starting logTool in the afternoon, I did a "Load" but no information was inserted; no software versions came up, nor weather, etc. Steph and the Malanushenkos had been running a logTool on pt1 which had information such as weather and mirror numbers in it, but had evidently never been made editable (the "Save" button was grayed out). Also, on starting logTool I got the error: 2005-10-24 00:57:13Z: Failed to execute command on observer@plate-mapper.apo.nmsu.edu; ssh error was 26120: WARNING: RSA1 key found for host plate-mapper.apo.nmsu.edu in /home/observer/.ssh/known_hosts:34 RSA1 key fingerprint 50:79:a0:1e:a2:71:9e:63:a8:30:c6:d3:79:97:99:46. 26120: Host key verification failed. .logtool.logviewer3 (Eric tells us this only affects the software version number as it is automatically entered in the "software" section of the log.) When I released the log I didn't save what I'd written, but copied it into a text file on landru, then saved and exited the logTool on pt1. I loaded that back into my logTool on landru and then pasted in what I had written in the team and log sections. Eric says that murmur should have been restarted after starting up new software versions (via a cleanupMurmur), and then to have restarted logTool after the cleanupMurmur (i.e., in the middle of the night). This should have happened sometime last night once the shake tasks were completed. Having not done so would explain the problems we have been seeing. We also note today that when we setup the test version of IOP (v4_6_0a), or set it up explicitly as 'setup iop 4_6_0a', this isn't the version reported by IOP at startup: IOP_VERSION=v4_6_0 or by doing an iopVer (v4_6_0). 'which iop', however, gives: /linuxp/prd/iop/v4_6_0a/bin/iop We also have: Executable was built against version v15_5 of the DA; setup version is v15_6 Warning: oacVersion v15_5 != version reported by crates is v15_6 Eric says both of these warnings are not real problems. He says that IOP versions 4_6_0 and 4_6_0a are identical products in CVS, their only difference being which version of astroDa is set up at the time IOP is started. With Eric's blessing, we declared the test version of IOP, v4_6_0a, current. Weather conditions held more or less steady into the early night. Humidity hovered in the high 70's, but at one point looked to be dropping into the 60's, so we decided to ventilate. Toward 04:30Z, however, the touch-test revealed significant amounts of water condensing on outdoor surfaces, and we closed the building back up. At 05:30Z we got a weather report from Steph after she arrived home. Patchy fog along NM 6563 from mile marker 11 through Cloudcroft. That just bolstered our decision to remain closed. Throughout the night humidity ranged up and down through the 70's and 80's, the split periodically dipping down below 3 deg C. Wind was almost nonexistent at < 5 MPH and the direction varying all around the horizon, bringing alternating periods of slightly drier (or wetter) air. Several times we thought the humidity was on the retreat and ventilated prematurely, only to have to go right back down and shut the fans off. Conditions never improved. We called it at 11:00Z with less than one hour to go until twilight. (*cue fog machine*) endNight complained about not finding the mcptpm log and do we REALLY want to continue anyway? We said yes. Eric? (endNight otherwise rejoiced...) ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5766 23:27Z 23:42Z 100 O 93.48 97.30 38 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): n UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 34284, plate -9999 ------- 23:29 34284 0.0 bias 23:35 34285 0.0 bias 00:07 34286 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 ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL Stays: JL ---=== 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 22:40Z 51 40 6 253 (WSW) -9999 - Clear 23:11Z 50 40 4 213 (SSW) -9999 - Clear 23:44Z 46 40 1 183 (S) -9999 - Clear 00:15Z 46 40 0 161 (SSE) -9999 - Clear 00:53Z 46 39 0 244 (WSW) -9999 - Clear 01:09Z 44 38 2 262 (W) -9999 - Clear 01:41Z 46 39 1 251 (WSW) -9999 - Clear 02:13Z 44 38 1 0 (N) -9999 - Clear 02:49Z 45 38 0 349 (NNW) -9999 - Clear 03:21Z 45 38 0 243 (WSW) -9999 - Clear 03:53Z 44 38 0 203 (SSW) -9999 - Clear 04:30Z 44 38 1 177 (S) -9999 - Clear 05:02Z 42 37 1 184 (S) -9999 - Clear 05:34Z 44 36 1 229 (SW) -9999 - Clear 06:06Z 41 36 1 246 (WSW) -9999 - Clear 06:38Z 44 37 2 260 (W) -9999 - Clear 07:10Z 44 36 0 238 (WSW) -9999 - Clear 07:43Z 44 36 2 261 (W) -9999 - Clear 08:15Z 43 37 0 224 (SW) -9999 - Clear 08:47Z 44 37 0 321 (NW) -9999 - Clear 09:19Z 43 37 2 336 (NNW) -9999 - Clear 09:51Z 42 37 0 322 (NW) -9999 - Clear 10:23Z 42 37 5 338 (NNW) -9999 - Clear 10:55Z 40 37 1 344 (NNW) -9999 - Clear 11:28Z 38 37 1 345 (NNW) -9999 - Fog ---=== TELESCOPE STATUS ===--- 03:40Z Fans on, doors open 04:28Z Fans off, doors closed (this sequence happened several times in the night...)
