APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday September 6, 2009 (MJD 55081) ---=== OBSERVING TEAM ===--- Kaike Pan Steph Snedden Paul Harding (remote) ---=== OBSERVING PLAN ===--- Continue the attempt to get a working guider. ---=== OBSERVING SUMMARY ===--- Worked on the guider fiber orientations and spiderInstAngle some more. We got the guider to work on cartridge 1 with a sign change to spiderInstAngle (was -90, is now +90). Found a few guide stars on cartridge 11 before clouds got us. Dan, please note that the spectro fill seems to take longer than it used to. Tonight it took a half hour with the pressure building on and pressure was high. This will be a problem when we are doing science and open at sunset. It could delay us getting to the first science field of the night. The spectro dewar will need replacing in the morning. ---=== OBSERVING LOG ===--- Afternoon: --------- Afternoon checkout only had one problem; We saw no altitude fiducial crossings at 45 and 60 degrees. Could the day staff investigate this please? 01:25Z - Started ventilation. Night: ----- While waiting for clouds to clear, we checked that the cartridge 1 guide fibers were correctly plugged, and of course, they were. We also did an occultation test using a pin above fibers 10 and 11 to verify Paul's fiber angles for those two fibers. 04:10Z - Opened enclosure for guider work using cartridge 1 04:41Z - The spectro fill took a half hour to complete. We then went to the field of cartridge 1, plate 3504 for more guider tests. Paul played with the spiderInstAngle. We tested offsets with a spider inst angle of zero, -90 and +90 deg. At -90, the guide loop pushed the stars off the fiber. At +90, with the signs flipped for rot and az (rot=-rot, az=-az) the guider pulled the stars to the fiber centers. Paul recorded the guider frame numbers for later analysis. 08:26Z - Cartridge 11, plate 3523 - BOSS ---------------------------------------- No guide stars. The plugMap file may be incorrect? We double checked that the correct plate was on the cartridge, and slewed to the field again. We then had a guide star at the edge of one of the big fibers (at about 5 o'clock). Some negative az offsets brought the star in closer to center, but we never got it exactly centered because clouds came in. Negative az offsets are shown in frames 0826 - 0828. 11:25Z The clouds persisted, and we closed up. endNight finished. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 8024 01:42Z 02:00Z 100 O 81.02 85.55 43 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 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== 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 00:43Z 57 45 0 242 (WSW) 950 - partly cloudy 01:16Z 55 43 3 157 (SSE) 855 - ' 01:48Z 55 42 0 231 (SW) 1020 - ' 02:20Z 54 43 2 225 (SW) 970 - ' 02:51Z 53 43 0 210 (SSW) 1009 - ' 03:23Z 53 43 3 171 (S) 1014 - ' 03:56Z 52 43 6 130 (SE) 1135 - ' 04:28Z 52 42 1 162 (SSE) 1183 - ' 05:00Z 53 43 9 133 (SE) 1030 - ' 05:32Z 53 43 6 126 (SE) 1224 - ' 06:04Z 52 44 13 125 (SE) 1409 - ' 06:36Z 51 45 10 124 (SE) 1476 - ' 07:08Z 51 46 6 122 (ESE) 1464 - ' 07:41Z 52 44 6 132 (SE) 1406 - ' 08:13Z 51 45 10 132 (SE) 1388 - ' 08:45Z 51 45 2 115 (ESE) 1479 - ' 09:17Z 50 44 3 193 (SSW) 1404 - ' 09:49Z 50 45 4 183 (S) 1423 - mostly cloudy 10:21Z 51 44 5 185 (S) 1268 - ' 10:53Z 52 44 2 189 (S) 1358 - ' 11:25Z 51 44 2 197 (SSW) 1307 - ' ---=== TELESCOPE STATUS ===--- 01:25Z - Started ventilation 04:10Z - Opened enclosure 11:19Z - closed enclosure.
