APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday December 4, 2004 (MJD 53344) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Howard Brewington Pete Newman ---=== OBSERVING PLAN ===--- Science. ---=== OBSERVING SUMMARY ===--- Snow prevented operations. ---=== OBSERVING LOG ===--- Afternoon: ---------- Afternoon check went smoothly. An adjustment to spectrograph focus was made, +2000 sp1, +3000 sp2 (about 2000 less than it wanted in each case as a temperature hedge). sp1: Coll_motor_A 3904 Coll_motor_B 1887 Coll_motor_C 504 sp2: Coll_motor_A 9335 Coll_motor_B -9089 Coll_motor_C -2864 Night: ------ Snow falling from sunset followed by full humidity and high winds. 09:30Z After a series of rapid utility power glitches, the alarm sounded on the compressed air dew point sensor outside the 1m control room. We reset the alarm and it did not recur. At the time, the reading was -37C. Could someone label that unit with the normal range, please? We started giving up around 10:00Z. endNight ran onto the Cloudy Night tapes. We told endNight to ship tapes by mistake, so please ignore the ship-tapes email. There is some minor quantities of water on the floor at the west side of both the upper and lower enclosures, but equipment seems to be well protected. We continue to not see false alarms from the TPM - nice! ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5027 21:56Z 22:04Z 100 O 112.22 114.21 27 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): N QA Procedures Done (y/n): N UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 29694, plate -9999 ------- 21:55 29694 0.0 bias 23:26 29704 0.0 bias 23:29 29705 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 ===--- A "Ship Tapes" email was sent in error.
