APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday October 5, 2004 (MJD 53284) ---=== OBSERVING TEAM ===--- Swing: Pete Newman Night: Jurek Krzesinski, Steph Snedden Visitor: Jen Adelman-McCarthy ---=== OBSERVING PLAN ===--- Shakedown items deferred from last night, then science. ---=== OBSERVING SUMMARY ===--- Rain, lightning, a tornado watch, followed by high humidity. Unfortunately, we still need to check collimation and get a pointing model. * Please leave the engineering camera mounted. * ---=== OBSERVING LOG ===--- Swing shift: No anomalies found during pre-flight checks. The engineering camera is mounted, so no spectrograph focus checks performed. Night shift: Severe weather watches including a tornado watch, and lightning all around kept us closed until 05:00Z. At that point we started enclosure ventilation. It was still overcast and the dewpoint split was marginal, so we did not open. 05:53Z The skies cleared out, but radiative cooling started to lower the dewpoint depression. We had to stay closed and at 06:20Z we shut off the ventilation system and turned on the heaters. Last night, the cleaning light came on the spectro-2 tape drive. A cleaning tape was used, and the light went out. Tonight the light was on again, but after writing to the tape, it went back out. A PR was filed. 11:23Z - We give up. We will go for collimation and a pointing model tomorrow before science. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 4862 22:24Z 22:38Z 100 O 60.20 63.62 36 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): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 28741, plate -9999 ------- 22:21 28741 0.0 bias ----- sequence 28742, plate -9999 ------- 00:23 28742 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: JLN/A Stays: JLN/A ---=== 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 22:01Z 58 40 16 200 (SSW) -9999 - 22:33Z 54 42 22 217 (SW) -9999 - 23:05Z 51 44 20 204 (SSW) -9999 - 23:37Z 52 39 21 201 (SSW) -9999 - 00:30Z 52 39 18 206 (SSW) -9999 - 01:02Z 51 41 21 200 (SSW) -9999 - 01:35Z 51 41 17 204 (SSW) -9999 - 02:07Z 49 42 3 320 (NW) -9999 - 02:43Z 50 42 13 212 (SSW) -9999 - 03:15Z 49 42 11 204 (SSW) -9999 - 03:47Z 50 41 7 225 (SW) -9999 - 04:20Z 48 41 7 189 (S) -9999 - 04:52Z 49 41 7 206 (SSW) -9999 - 05:24Z 48 42 6 179 (S) -9999 - 05:56Z 48 42 10 216 (SW) -9999 - 06:29Z 48 43 9 214 (SW) -9999 - 07:01Z 47 44 8 210 (SSW) -9999 - 07:33Z 47 45 7 194 (SSW) -9999 - 08:05Z 47 45 4 185 (S) -9999 - 08:37Z 47 43 3 211 (SSW) -9999 - 09:10Z 47 45 10 227 (SW) -9999 - 09:42Z 47 45 6 217 (SW) -9999 - 10:14Z 47 44 8 212 (SSW) -9999 - 10:46Z 46 43 6 189 (S) -9999 - 11:19Z 44 43 4 184 (S) -9999 - ---=== TELESCOPE STATUS ===--- 05:00Z - Opened doors and started ventilation. 06:20Z- Closed doors.
