APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday August 24, 2007 (MJD 54337) ---=== OBSERVING TEAM ===--- dayShift: Howard Brewington Dan Oravetz, Elena Malanushenko ---=== OBSERVING PLAN ===--- BR - Spectro Science! ---=== OBSERVING SUMMARY ===--- We did not open tonight because of thunderstorm and clouds. Primary dewar does not hold the pressure and needs to be replaced. ---=== OBSERVING LOG ===--- Afternooon: ----------- Since Steph made the -t ver of IOP current, I restared the servers. The spectro focus was checked but not adjusted; it's set to about 15-degrees C. The numbers are posted in the Problems Section. Watcher reported sp1's mechanicals as, "Not Connected." Other misc Watcher messages are posted in the Problems Section. Using the byebye script, I deleted all MJDs marked as, "Safe to Remove." The disk space is now: /dev/md6 367G 323G 26G 93% /data sdssfiles1:/data1/data 1.5T 522G 871G 38% /files I could not start ventilation because of bad weather in the area. Night: -------- We had clouds, strong radar return from all directions, and lightening. We did not open tonight. Spectro dewar had low pressure around 12 psi, and secondaries had 5-6 psi. I rebuilt the pressure, forced the filling of secondaries, and they have 10 psi as expected. But the primary dewar does not hold the pressure and needs to be replaced. endNight is completed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6907 20:33Z 20:56Z 100 O -9.82 -3.98 53 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 46125, plate -9999 ------- 20:32 46125 0.0 bias ----- sequence 46126, plate 2624 ------- 21:50 46126 10.0 flat 21:52 46127 2.0 arc 21:59 46128 3.0 arc 22:01 46129 2.0 arc ----- sequence 46130, plate -9999 ------- 01:02 46130 0.0 bias 01:22 46131 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 ===--- ---=== 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 19:54Z 69 55 11 228 (SW) 735 - 20:26Z 67 55 13 212 (SSW) 718 - 20:56Z 67 53 14 213 (SSW) 634 - 21:27Z 71 55 11 230 (SW) 632 - 21:57Z 70 54 9 213 (SSW) 579 - 22:29Z 69 54 6 218 (SW) 606 - 22:59Z 62 52 5 86 (E) 669 - 23:31Z 60 51 14 127 (SE) 1058 - 00:03Z 61 53 8 184 (S) 611 - 00:36Z 60 53 13 134 (SE) 765 - 01:29Z 59 50 0 143 (SE) 591 - 02:02Z 61 50 2 176 (S) 659 - 02:34Z 61 48 1 131 (SE) 587 - 03:06Z 62 48 1 176 (S) 554 - 03:38Z 62 47 7 230 (SW) 465 - 04:10Z 62 47 1 143 (SE) 551 - 04:42Z 62 46 3 228 (SW) 492 - 05:14Z 61 43 7 185 (S) 342 - 05:47Z 59 43 5 135 (SE) 263 - 06:19Z 59 42 2 123 (ESE) 232 - 06:51Z 59 41 4 105 (ESE) 180 - 07:23Z 59 41 6 120 (ESE) 208 - 07:55Z 60 43 2 190 (S) 474 - 08:27Z 61 47 3 261 (W) 575 - 08:59Z 61 42 6 196 (SSW) 425 - 09:36Z 60 43 2 252 (WSW) 299 - 10:08Z 59 44 5 340 (NNW) 278 - 10:40Z 59 45 1 325 (NW) 262 - ---=== TELESCOPE STATUS ===--- Did not open.
