APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday September 17, 2010 (MJD 55457) ---=== OBSERVING TEAM ===--- Kaike Pan Elena Malanushenko Craig Loomis - help with guider ---=== OBSERVING PLAN ===--- Science! MARVELS until 08:35 (6.6 h), then BOSS (2.9 h) ---=== OBSERVING SUMMARY ===--- There was high humidity for the whole night. We opened when the humidity dropped a little and started an exposure but aborted it and closed again. We had a problem to find guider stars on ct5/pl3519/B. ---=== OBSERVING LOG ===--- Afternoon: ---------- Actors were checked. gcameraICC was down and it was restarted. 00:10Z MARVELS lamps on. Altitude fiducial did not readout at 46 in both directions. Delay with ventilation because of high humidity. Boss calibration and collimation were in spec, no adjustments. Night: ------ High humidity, clouds, nearby radar return. We was waiting for weather improvement. 03:14Z it was clearing out, but the humidity is still high, 03:40Z The humidity was better (75%) and difference 3.5-4.0C. The humidity inside enclosure was 91%. We need to wait more. 04:30 Started ventilation. The humidity inside enclosure was 86%. We think this is ok. 05:00Z enclosure is off calibration T05:04:48.420 Cart 5 plate 3519B Marvels 05:15 gotoField We had a problem to find guider stars. We found two stars on GTF, but, we think, one of them was not right guider star. We tried to offsets to other pointing and finally found stars. Scale correction wa about 0.03. Seeing ~1.2" Humidity is going up, 80%. Difference is 3.3C. Touch test - very cold, but ok. T06:01:45.770.fits This exposure was aborted because high humidity. 06:30. Enclosure was on. Ventilation was stopped. The humidity is still too high for observations, 92%, and diff 1.2C. 11:10Z endNight ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- ---=== 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 Reading FITS from /data/MARVELS/55457/et1/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Image Cart Plate Texp Exptype Object - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - T05:04:48.420 0 11. 44889. 4954.
