APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday June 29, 2003 (MJD 52820) ---=== OBSERVING TEAM ===--- Night: Howard Brewington Scot Kleinman Connie R. (by phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds, humidity, wind, dust, and a broken spectrograph did not allow us to get any science done tonight. SP1 is still down (only one exposure lost "thanks" to the bad weather) and will need to be dealt with by the day staff. ---=== OBSERVING LOG ===--- Afternoon: ------------- During afternoon checkout, ID3-1 asked to be cleaned, so I cleaned it. And, the instrument lift at the 2.5m had moved up slightly since this morning, which caused the telescope to abort in the alt axis. Spectro focus was checked; it was within spec. Night: _____________ We still had some clouds in the area, so we started with spectro. Scot got an error message in his sop session during the beginning of the night; see problems section (problem one). We've seen this error before and have "recovered" from it by dropping and re-rabbing the instruments, but would like to know how serious the error condition is -- do we really need to work around it or can we just ignore it? Spectro: 03:20Z cart 03, plate 1371. Fk5 star used to find the field, but we started before twilight, so this may be due to the bright sky. At any rate, the fk5 star was easily found.; seeing ~2.0" After the 1100 second exposure, the image could not be readout. We called Connie; see problems section (promlem two). ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4019 23:09Z 23:17Z 100 O -25.79 -23.76 27 ignore 4020 23:32Z 23:49Z 100 O -20.22 -15.78 44 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 21609, plate -9999 ------- 23:12 21609 0.0 bias ----- sequence 21610, plate 1033 ------- 23:40 21610 10.0 flat 23:43 21611 2.0 arc 23:49 21612 2.1 arc 23:51 21613 2.1 arc ----- sequence 21614, plate 1033 ------- 00:28 21614 0.0 bias ----- sequence 21615, plate 1371 ------- 03:40 21615 10.0 flat 03:42 21616 2.0 arc ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ 03:47Z 3 1371 236.96 0.0040 55.06 0.0035 84.60 0.0090 1.000300 03:48Z 3 1371 236.99 0.0040 54.91 0.0035 84.77 0.0090 1.000300 ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== DATA TAPE SUMMARY ===--- Goes: JL cloudy 1 Stays: JL cloudy 2 ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ 03:47Z 3 1371 1.00030 -2961 -1487 -200 237 55.1 14.1 15 72 03:48Z 3 1371 1.00030 -2961 -1487 -200 237 55.0 14.0 17 74 gdr 2.0 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:57Z 66 32 9 63 (ENE) 333 - thin clouds 23:28Z 63 34 1 253 (WSW) 371 - thin clouds 23:59Z 64 33 6 78 (ENE) 361 - thin clouds 00:30Z 62 36 10 85 (E) 508 - thin clouds 01:02Z 61 35 11 83 (E) 582 - thin clouds 01:34Z 60 36 10 85 (E) 566 - thin clouds 02:07Z 59 36 19 71 (ENE) 547 - thin clouds 02:40Z 57 36 17 72 (ENE) 648 - thin clouds 03:10Z 57 37 13 80 (E) 930 - thin clouds 03:43Z 57 37 13 77 (ENE) 853 - clouds 04:15Z 56 36 25 80 (E) 617 - clouds 04:46Z 51 39 24 74 (ENE) 3350 - clouds 05:18Z 49 44 33 72 (ENE) 5614 - clouds 05:48Z 49 45 22 67 (ENE) 4271 - clouds 06:18Z 48 46 30 72 (ENE) 3382 - clouds 06:51Z 48 46 28 74 (ENE) 2496 - clouds 07:21Z 49 47 27 79 (E) 2133 - clouds 07:51Z 48 47 32 72 (ENE) 794 - clouds 08:21Z 47 47 17 74 (ENE) 1823 - clouds 08:51Z 47 47 18 91 (E) 1065 - clouds 09:22Z 47 47 22 73 (ENE) 676 - clouds 09:52Z 47 46 22 78 (ENE) 461 - clouds 10:22Z 46 46 16 75 (ENE) 1239 - clouds ---=== TELESCOPE STATUS ===--- 01:10Z Doors open, fans on 02:30Z Enclosure off 04:45Z Enclosure on, fans off, shut down.

He did a grabInstrument -drop and then grabInsts again, which seemed to solve the problem. We've seen this same error message several times in the past. And, we always solved it as described above. Is this really a problem? Should we just continue to use the method described above to deal with the error message below or can we do nothing and proceed?

We determined that sp2 was working okay, but sp1 was not. We could not talk to SP1 (cc ping did not return a PING). We recycled the power switch on the spectro power suppies; unfortunately, sp1's operation was not restored (well it was for a brief moment, but it didnt last). Next, we tried replacing both of the power supplies with spare ones found in the imager parts cabinet. Afterwards, sp1 was still not working. Connie now feels the problem may be the two-level (micro controller) board. We think we found a spare board; it is located in the spectro parts cabinet on top of the box marked Spectro CCD Electronics. Connie said that this board was much more difficult to change-out as compared to the power supply units, so she suggested that, since the weather conditions would not allow observations and no science time was being lost, we let the engineering staff handle the spectro repair in the morning. We left the spare spectro power supplies mounted on the telescope. And the power supplies, which were originally mounted on the scope, are sitting atop the workbench on the north-side of the upper 2.5m enclosure. The board placed on the right side of the bench was mounted in the right slot of the telescope, and so on. Connie says the CCD LN2 fills should continue even with non-running micros, but she's not sure. We've been recycling SP1's power every couple of hours to ensure a fill. The last such power recycling was shortly before 05:00 APO time.
