APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday December 24, 2005 (MJD 53729) ---=== OBSERVING TEAM ===--- Swing: Dan Long Night: Mike Harvanek Elena Malanushenko Viktor Malanushenko Fritz Stauffer (by phone) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Finished 7 plates (1914, 2339, 2070, 2055, 2283, 2225, 2236). sdss-commish hung. No other problems. Merry Christmas to all and to all a good night. ---=== OBSERVING LOG ===--- Afternoon: Spectro focus checked. No changes made. Still set for between 3 and 4 C. No problems encountered during checkout. However, another day another oddity. When fiducializing, I found the altitude off by nearly 3 degrees. Position was reset, and fiducials were no longer too large to correct, and as a sanity check I verified the altitude pin would go in at 90 degrees. Night: Light cirrus so we begin with spectroscopy. Plate 1914 (cartridge 2): Segue. Guide stars on the gotoField. The 1st science exposure was started about 15 minutes before twilight ended. The 3rd science exposure (frame 35804) had S/N^2 = 1.9 for r1. I checked the old SoS version results for comparison but, for whatever reason, it's not running. Yesterday's results are there but today's are not. I did NOT declare this exposure bad because I'm not sure that it is. However, I did not count the S/N from this exposure in the total used to declare it done either. So, if this exposure is bad, the reduction folks can declare it so. If it's good, you've got some bonus S/N. SoS called for a postCal after the 2nd science frame so we did a midCal after the 3rd frame completed. sdss-commish crashed around 03:05Z. Fritz Stauffer (and Fritz Dejongh!) were called (sorry guys) and we had to power cycle commish. I (Mike) had to restart all of my windows because my window manager runs on commish. Fortunately, no telescope time was lost because Viktor and Olena were driving from landru. After commish was power cycled, the results from the old SoS started to appear. Indeed, the old SoS calls the 3rd exposure (frame 35804) good. We more than finished this plate with 4 good exposures (5400 sec total) and if frame 35804 (1200 sec) is good too, this plate has lots of bonus S/N. There is a long list of SoS warnings for this plate. SoS called for a postCal after the last exposure but we had already changed the cartridge. Plate 2339 (cartridge 8): Segue faint. Guide stars on the gotoField. Finished in 4 good exposures (6600 sec total). There was a whopping fiber warning. We did a postCal as requested. Although photometric now, variable seeing (a strong north wind) prevented us from switching to imaging. Plate 2070 (cartridge 7): Segue faint. Guide stars on the gotoField. We had time for only 1 exposure (1800 sec) and this went 12 minutes beyond the plate expiration time. When combined with data from the previous 2 nights (53727, 53728), we finished this plate. There was a single whopping fiber warning. Seeing still variable so we continue with spectroscopy. Plate 2055 (cartridge 6): Segue. Needed an FK5 to acquire the guide stars. We took 4 exposures (6900 sec total). According to the new SoS, all 4 had insufficient S/N in r1. The old SoS said that only the last 2 had insufficient S/N in r1. All 4 exposures were taken in good conditions; i.e., photometric, little or no moon, okay to good seeing. The conditions aren't going to get alot better. If these exposures really are bad, there must be a problem with the plate. There is sufficient S/N in the b cameras to declare this plate done and that's what were doing. If the reduction folks aren't happy with it, they can declare it undone and we'll reobserve it. There's a huge list of SoS warnings. We did a postCal as requested. Seeing has improved but the moon is now up. Spectroscopy for the rest of the night. Plate 2283 (cartridge 5): Survey. Guide stars on the gotoField. Three of the guide fibers (2, 7, 11) had their little red guiding cross (not to be confused with Little Red Riding Hood) way outside of the guide fiber. We took another guider flat but this did not help so we just disabled guiding for these 3 fibers. We finished this plate in 3 exposures (3300 sec total). SoS warned of a whopping fiber. We did a postCal as requested. Plate 2225 (cartridge 4): Survey. Needed an FK5 to acquire the guide stars. Guide fiber 11's little red guiding cross has gone astray. It was disabled. Fiber 5 was also disabled because it's "star" was very elongated and had a FWHM more than twice that of the other guide stars. When combined with data from last night (53728), we finished this plate in a single 1200 sec frame. No SoS warnings. Plate 2236 (cartridge 3): Survey. Guide stars on the gotoField. Guide fiber 2 was disabled due to its little red guiding cross being way outside its guide fiber. This plate was finished in 3 exposures (2700 sec total). No SoS warnings. endNight rejoiced. Merry Christmas. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 5953 19:16Z 19:33Z 100 O 91.63 95.90 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): YES QA Procedures Done (y/n): YES UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ----- sequence 35793, plate -9999 ------- 19:18 35793 0.0 bias ----- sequence 35794, plate 2225 ------- 19:22 35794 10.0 flat 19:24 35795 2.0 arc 19:31 35796 2.1 arc 19:34 35797 2.1 arc 23:1Z 35798 0.0 bias 00:00 35799 0.0 bias ----- sequence 35800, plate 1914 ------- 19.9 12.6 29.5 22.6 DONE 01:10 35800 10.0 flat 01:12 35801 2.0 arc 01:37 35802 1200.1 target 01:59 35803 1200.1 target 02:22 35804 1200.1 target low r1 s/n - not used in s/n total - bad???
