APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday April 2, 2003 (MJD 52732) ---=== OBSERVING TEAM ===--- Swing: Atsuko Nitta Night: Mike Harvanek Dan Long ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Night lost to clouds. ---=== OBSERVING LOG ===--- Afternoon --------- Spectro focus checked and all within tolerance. We have a new handle to open/close the hatch. It has a knob that will allow us to open from the lower enclosure in case we are trapped in there and we cannot escape from the door. Night ----- The entire night was lost to clouds. While doing the spectro QA, Dan noticed that the fibers in the 5th bundle (fibers 81-100?) of spectrograph 1 on cartridge 7 were dimmer than those in other bundles. For example, on a flat, the 5th bundle fibers on r1 were about 30% dimmer than those in neighboring bundles and about 10% dimmer on b1. Inspection of previous nights' data showed this to be a regular occurrence. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 3844 23:13Z 23:35Z 100 O -111.69 -106.08 51 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 20173, plate -9999 ------- 23:08 20173 0.0 bias ----- sequence 20174, plate 1047 ------- 23:22 20174 10.0 flat 23:26 20175 2.1 arc 23:29 20176 2.1 arc ----- sequence 20177, plate -9999 ------- 00:56 20177 0.0 bias 00:59 20178 0.0 bias ----- sequence 20179, plate 1047 ------- 02:05 20179 10.0 flat 02:07 20180 2.0 arc 11:15 20181 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: None Stays: None ---=== 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 23:00Z 49 28 27 246 (WSW) 2508 - tcl 23:32Z 49 28 24 268 (W) 2811 - " 00:04Z 48 24 28 263 (W) 2842 - " 00:38Z 47 25 33 253 (WSW) 1575 - " 01:17Z 45 25 25 263 (W) 1293 - " 01:49Z 44 26 17 248 (WSW) 959 - " 02:20Z 44 24 23 248 (WSW) 846 - " 02:50Z 42 25 14 243 (WSW) 710 - " 03:21Z 43 22 22 237 (WSW) 637 - " 03:52Z 43 20 25 267 (W) 718 - " 04:22Z 42 18 21 239 (WSW) 615 - " 04:53Z 41 18 24 236 (SW) 569 - " 05:24Z 41 18 15 237 (WSW) 589 - " 05:54Z 40 20 17 226 (SW) 564 - " 06:25Z 39 21 10 253 (WSW) 711 - " 06:55Z 39 21 14 238 (WSW) 557 - " 07:25Z 39 20 14 258 (WSW) 461 - " 07:55Z 39 18 14 266 (W) 397 - " 08:25Z 38 18 16 269 (W) 376 - " 08:57Z 38 18 14 260 (W) 379 - " 09:28Z 37 16 15 259 (W) 357 - " 09:58Z 36 19 21 264 (W) 394 - " 10:29Z 36 19 13 271 (W) 382 - " 10:59Z 34 24 21 266 (W) 402 - " tcl = totally cloudy ---=== TELESCOPE STATUS ===--- 04:35Z Enclosure doors opened, fans and blowers on, louvers opened. 10:45Z Doors closed, fans and blowers off, louvers closed.
