APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday August 10, 2001 (MJD 52132) ---=== OBSERVING TEAM ===--- Stephanie Snedden (APO) Pete Newman (APO) Eric Neilsen (FNAL) ---=== OBSERVING PLAN ===--- Verify the pointing model, and take science data (with test versions of the software, to shake it). ---=== OBSERVING SUMMARY ===--- Another night lost to weather: heavy clouds early, then high humidity, a brief opening followed immediately by closure due to lightning, questionable humidity, and returning clouds. ---=== OBSERVING LOG ===--- Afternoon tasks: ---------------- In preparation for the dark run, Steph ran through the afternoon setup of the 2.5-m instruments and PT. The current plan is for the PT biases, dome and twlight flats, pointing correction and focus to be completed before the PT is handed over to the observers. The 2.5-m instruments and the DA will also be checked during the afternoon, but the telescope itself will be checked by the night's observers. Night "observing": ------------------ There are thick clouds at sundown. We close the PT and finish the telescope checkout, but do not open. Around 11:00, it looks as if it might be clearing, and we consider opening. Before we do, it clouds over again and the humidity rises. Around midnight, the clouds mostly clear up, but the humidity is too high to open. At 3:20, the humidiy finally drops enough that we can open, but just barely. We open, and obtain a star in the engineering camera. Clouds are a problem in focusing, and we eventually loose our star to clouds. As we are attempting this, the dewpoint depression creeps back down to 4 degrees and the are lightning strikes within 15 miles; we close at 4:20. By the time we finish closing and changing the spectrograph dewar, the clouds are gone, but it is too late to reopen. ---=== IMAGING RUN SUMMARY ===--- Run Stripe Flavor Lambda Last Begin End Frame Comments ------------------------------------------------------------------ 2484 100 O bias 24.28 30.21 54 ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot --------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields nGood rowMean rowSig colMean colSig rot --------------------------------------------------------------- ---=== SPECTROSCOPY DATA SUMMARY ===--- UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument getclock Az Alt Rot Scale ------------------------------------------------------------------------------ ---=== 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 ------------------------------------------------------------------------------06:39 imager 1.00000 0 -2271 0 121 30.0 12.7 11 184 ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 23:38 54 47 5 126 (SE) 706 - cloudy 00:10 53 48 3 126 (SE) 792 - cloudy 01:15 54 48 7 181 (S) 799 - cloudy 02:07 53 48 4 187 (S) 776 - cloudy 02:39 53 48 7 180 (S) 780 - cloudy 03:15 55 45 7 186 (S) 724 - partly cloudy 03:48 54 45 9 181 (S) 688 - partly cloudy 04:20 54 46 4 182 (S) 704 - cloudy 04:52 54 45 4 180 (S) 699 - partly cloudy 05:24 54 45 8 181 (S) 771 - mostly clear 05:57 55 46 8 182 (S) 773 - 06:29 54 46 8 172 (S) 825 - 06:39 54 46 11 184 (S) 868 - ---=== TELESCOPE STATUS ===--- Stowed at 30 deg alt, engcam installed.
