APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday January 28, 2003 (MJD 52668) ---=== OBSERVING TEAM ===--- Swing: Howard Brewington Night: Dan Long Peter Newman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We got about three hours of imaging done in the first half of the night, and five plates done during the second half. 01:30Z Run 3634 62 N special science -155 to -141 ( entire Abell strip ) 03:15Z Run 3635 27 S science -62 to -40 06:50Z Cartridge 5 1189: 12.0 11.3 11.0 9.2 Done 07:40Z Cartridge 6 1197: 22.1 15.9 18.5 18.5 Done 09:00Z Cartridge 8 1200: 4.9 4.5 4.5 4.2 Done 10:10Z Cartridge 7 1158: 22.3 19.2 20.4 14.2 Done 11:30Z Cartridge 9 1162: 20.9 18.5 20.6 15.6 Done One PTVME failure during twilight. M2 galil lost track of position probably due to power glitch. PR 4744 filed. ---=== OBSERVING LOG ===--- Afternoon biases from spectrographs were examined and look normal. Bias ( 3633 )taken with the imager in the enclosure at about sunset ( doors closed, no enclosure stop buttons in, laptop covered ). PTVME error while waiting for the spectrographs to fill ~01:10Z. No activity with the imager at the time. See problem section for ptvmeTest results. Clear during the afternoon and early evening, so we start with the imager. 01:30Z Run 3634 62 N special science -155 to -141 ( entire Abell strip ) In focus by frame 22 ( lambda -161 ). Skippy also happy. Twilight by frame 55 ( lambda -156.5 ). Complaint during imager primary fill: ln2 empty (2003-01-29 01:39:02Z) 02:00Z Gang transfers stopped for about 10 frames. Restarting teamster got things going again. 02:37Z 7 chips under .8" ( lambda -146 ). 03:02Z frame 157 ( lambda -141 ) center of end of scan Note: There was no entry in logTool for run 3634 and i4l wouldn't generate one. The runlog for 3634 also has bogus entries for the end, possibly the reason for the lack of an entry in the imaging summary? 03:15Z Run 3635 27 S science -62 to -40 In focus by frame 10 ( lambda -65.4 ). Skippy also happy. Faint wisp of cirrus ( contrail? ) right at start of setup ( before start of science ). Frame 19 ( lambda -64 ) start of ramp up. Frame 32 ( lambda -62 ) start of science. Frame 150, faint structure visible in cloud camera ( sdev still ~ 4 ) Frame 170 ( lambda -41.4 ) seeingRun now calls it bad starting here with data to frame 190. Frame 182 ( lambda -39.6 ) seeingRun plot crosses the red line Frame 230, ( lambda -30.5 ) seeing trending back down. Ending drift and moving to another higher priority stripe. 05:30Z Run 3636 16 N ignore due to bad seeing In focus by frame 10 ( lambda -66.5 ). Skippy also happy. Seeing 1.3" Frame 19 ( lambda -65 ) start of ramp up. Frame 33 ( lambda -63 ) start of science. Frame 45 seeing goes from 1.3 to 2.3 in essentially one frame Frame 55 seeing goes from 1.8 to 1.3 in essentially one frame Ending this drift, backing up and trying again. 06:10Z Run 3637 16 N ignore due to bad seeing Run is good from the start ( lambda -65 ). Seeing never cooperated. On to spectroscopy 06:50Z Cartridge 5 1189: 12.0 11.3 11.0 9.2 Done One guide star on slew. Finished in one exposure. Adding data from 52663 8.5 9.3 8.9 8.0 Total 20.5 19.8 19.9 17.2 07:40Z Cartridge 6 1197: 22.1 15.9 18.5 18.5 Done No guide stars. Needed to go to FK5 star. Took a bit of searching to find it at the acquisition elevation of 81 degrees. 09:00Z Cartridge 8 1200: 4.9 4.5 4.5 4.2 Done Guide stars on slew. Lost stars on scale change. Secondary dropped communications apparently due to power glitch. Homed secondary and returned to field after 20 minute break. Finished in one exposure. Adding data from 52662 12.0 18.3 12.5 17.8 Total 16.9 22.8 17.0 22.0 10:10Z Cartridge 7 1158: 22.3 19.2 20.4 14.2 Done Guide stars on slew ( after clearing offsets ). More substantial clouds move in during first exposure. They don't slow us down much. Still done in three exposures totaling 45 minutes. 11:30Z Cartridge 9 1162: 20.9 18.5 20.6 15.6 Done Guide stars on slew Some cirrus throughout, but good signal. Done in two when previous data included. Took additional exposure since a little time remained before twilight. Adding data from 52662 4.3 5.2 5.0 5.3 Total 25.2 23.7 25.6 20.9 13:00Z Twilight is upon us so we close up for the night, putting an early night cartridge ( 1 ) on the telescope. ---=== IMAGING RUN

This was noticed during a scale change. Apparently it briefly lost power. All positions "nined" out, claimed axes not homed. Hosted to secondary and homed secondary with no trouble. Below is the output of the TCC when the scale change failed. 0 I Modu="exe_BrdTelPos"; Text="4519550 packets sent successfully" 0 0 I PrimDesOrient=-1875.70, -11.80, 23.00, 1256.90, 642.10; PrimConstRMS=0.00 0 0 I SecDesOrient=-581.53, 0.00, -20.00, 0.00, -94.35; SecConstRMS=0.00 0 0 I PrimCmdMount=34818.,25742.,30364.,-208.,31612.,30735.; CmdDTime=2.1 0 0 I TrackAdvTime=3.49 0 0 I PrimMount=34800., 25750., 30350., -200., 31600., 30750. 0 0 I PrimOrient=-1875.21, -11.65, 22.81, 1257.18, 642.77 0 0 F Modu="prt_ReadMatch"; Text="bad reply"; Expected="A=-696673.; B=-761036.; C=-739982.; D=6561.; E=1975.; MG "OK""; Received="154.; MG "OK"" 0 0 F Modu="mir_o_MoveOneGalil"; Text="could not specify new positions for Sec mirror actuators" 0 0 W Text="failed to adjust collimation and focus" 0 0 I TCCStatus="TTT","NNN"; TCCPos=239.13,69.81,73.12; AxePos=239.13,69.81,73.12 Looking back in the TCC logs, the first sign of trouble with the secondary was actually at about 08:30Z 2003-01-29 08:31:39.714Z 0 0 F Modu="mir_o_MoveOneGalil"; Text=" Sec returned an error message" 2003-01-29 08:31:39.715Z 0 0 I Received="?HMERR some axes to be moved have not been homed 1, 1, 1, 1, 1" 2003-01-29 08:31:39.716Z 0 0 W Text="failed to adjust collimation and focus" The error was missed in the watcher and only became apparent when the scale was changed, which requires a large movement of the secondary. Why the power glitched/position was lost is not known. Do we have a flaky power supply or cable?
