APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 21, 2007 (MJD 54122) ---=== OBSERVING TEAM ===--- Viktor Malanushenko (day staff & observer) Olena Malanushenko (day staff & observer) Stephanie Snedden (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We did not open telescope - snow and ice on the enclosure and rails; high humidity; clouds; and strong radar return from another nearby storm. The storm came to us by the mid night with strong wind and snow. During afternoon checkout we could not track rotator and got big differences for mirror numbers. French is going to carry about the problems tomorrow. Weather station does not display wind parameters and watcher complains about wind of -9999 mph. We forced spectro to fill at 03:10 Z. Spectro dewar needs to be replaced after one next filling. Power is from genetrator. ---=== OBSERVING LOG ===--- Afternoon --------- During afternoon checkout we could not move telescope because three dewars were connected to imager to keep its filling longer. We have two problems: -we could not track the rotator for getting mirror numbers as it was halted ; -difference of mirror numbers for E and F are large. Lateral E 9.9060 9.9695 Lateral F 11.4681 11.5443 French is going to carry about the problems tomorrow. Night ------- The weather condition is still bad. We have one storm is over and two more are coming to us. Humidity humidity 80-100%, diff 0-1 C; T = -7C, dust and wind are not defined. We did not open telescope because of: snow and ice on the enclosure and rails; high humidity; clouds and fog on site; and strong radar return from another nearby storm. Wind detector on weather station does not show wind and watcher complains about wind -9999 mph. 03:10 Z Forced to fill spectro. It was in auto position but did not fill spectro for more then 16 hours. We decided to force filling using start button. It took 38 lb and stopped itself. 08:35 Z Power supply is switched from line to generator. During the night we had watcher messages: wind: winds (-9999 (low) 07:03Z) wind: gusts (-9999 (low) 07:03Z) Camera Systems: Spec1: Mechanical : not connected (1:) MCP: dewar (Spectro Dewar Low Weight:: 2007-01-22 07:00:07Z) The storm came to us. Snow, strong wind, very cold, high humidity. 09:40 Z. endNight is completed. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6683 22:43Z 23:01Z 100 O 170.98 -184.58 44 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 42598, plate -9999 ------- 22:24 42598 0.0 bias ----- sequence 42599, plate 2637 ------- 22:57 42599 10.0 flat 22:59 42600 2.0 arc 23:23 42601 3.0 arc 23:25 42602 3.0 arc ---=== 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 21:36Z 22 19 -9999 -9999 (N) 289 - clouds 22:09Z 25 25 -9999 -9999 (N) 248 - 22:39Z 22 21 -9999 -9999 (N) 1520 - 23:12Z 23 22 -9999 -9999 (N) 241 - 23:42Z 21 17 -9999 -9999 (N) 194 - 00:12Z 21 21 -9999 -9999 (N) 6940 - 00:43Z 21 20 -9999 -9999 (N) 569 - 01:13Z 20 19 -9999 -9999 (N) 334 - 01:43Z 20 19 -9999 -9999 (N) 298 - 02:14Z 19 18 -9999 -9999 (N) 214 - 02:42Z 19 17 -9999 -9999 (N) 214 - 03:12Z 19 17 -9999 -9999 (N) 184 - 03:42Z 18 17 -9999 -9999 (N) 189 - 04:13Z 18 17 -9999 -9999 (N) 308 - 04:45Z 18 16 -9999 -9999 (N) 161 - 05:17Z 16 14 -9999 -9999 (N) 106 - 05:49Z 16 14 -9999 -9999 (N) 167 - 06:22Z 15 13 -9999 -9999 (N) 417 - 06:54Z 13 11 -9999 -9999 (N) 2479 - 07:26Z 12 9 -9999 -9999 (N) 1675 - 07:58Z 12 10 -9999 -9999 (N) 1389 - 08:30Z 12 9 -9999 -9999 (N) 1579 - 09:03Z 11 8 -9999 -9999 (N) 323 - 09:35Z 11 8 -9999 -9999 (N) 286 - ---=== TELESCOPE STATUS ===--- Snow and ice on the enclosure and rails.
