APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday May 12, 2007 (MJD 54233) ---=== OBSERVING TEAM ===--- Swing: Viktor Malanushenko Observers: Elena Malanushenko, Dan Oravetz ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Clouds and radar returns early and then the sky cleared. Humidity was ~70% all night. Spectroscopy: We had some problems with percent scale adjustments for Cartridge 3. We kindly ask that Cartridge 3 be checked out. See log. Cartridge 4, plate 2742, chunk165, Legacy: FINISHED Cartridge 5, plate 2747, chunk165, Legacy: FINISHED Good signal on Cartridge 8, plate 2195, seguefaint118. ---=== OBSERVING LOG ===--- Afternoon: --------- Afternoon checkout went smoothly. No problems to report. Spectro focus has been adjusted to night temperature T=+7.5C. Did not begin ventilating because of clouds, sporadic rainfall and high probability of thunderstorms according to radar station's web-page. Night: ----- 02:35Z - Began ventilation. Doors and louvers opened, fans on. 03:07Z - Enclosure off. 03:28Z - Enclosure on due to nearby radar returns, but still ventilating. 04:00Z - Enclosure off. Cartridge 3, plate 2599, chunk153, Legacy. Guide stars found on gotoField after using an offset (guide star in fiber 5 was seen glowing just outside of the fiber's edge). The Guider Data Window was asking for percent scale change 0.024 and we could not adjust the scale without losing guide stars. We made several attempts and finally we skipped this cartridge. Details of the situation are described below. 04:23Z - Guide stars found on gotoField after using an offset (guide star in fiber 5 was seen glowing just outside of the fiber's edge). After a scale change and focus adjustment only 2 guide stars were present, so another gotoField was used in attempt to reacquire the field. Only 2 guide stars were found again, so we cleared the offsets and issued another gotoField. No guide stars were found, so then we tried an fk5 and couldn't locate it either. Finally, we set the scale back to 1.000000 and then tried an fk5. Now the fk5 star is seen in fiber 10, so we centered it and stickied the offsets and issued gotoField again. No guide stars were seen. We went back to the fk5 and stickied the offsets again (just to make sure). This time guide stars were found on gotoField. When we adjusted the scale according to the percent scale values given in the Guider Data Window, we lost guide stars, and the percent scale values increased. For instance, it was asking for a scale change of 0.024, so we applied 0.01 and then it asked for 0.04. Our several attempts to change the scale resulted in scale values subsequently larger and guide stars lost. Perhaps Cartridge 3 needs to be checked? We moved to Cartridge 4 to see if we experienced similar behavior and we did not. Cartridge 4, plate 2742, chunk165, Legacy. Guide stars found on gotoField using a small offset (could see the glow of a guide star just off the edge of one of the fibers). The guider centered the stars and the scale changes worked normally. We did not experience the problems described above for Cartridge 3. 05:07Z - Pre-Calib. 05:14Z - 20-minute exposure. 05:37Z - 20-minute exposure. 06:01Z - 20-minute exposure. 06:23Z - 22.5-minute exposure. Seeing: 2.1" - 2.5". SoS recommended post-calibs, but we already began the next plate. Finished this plate. Cartridge 5, plate 2747, chunk165, Legacy. Guide stars found on gotoField. 07:04Z - Pre-Calib. 07:10Z - 20-minute exposure. 07:34Z - 20-minute exposure. 07:57Z - 20-minute exposure. 08:21Z - 20-minute exposure. Seeing: 1.7" - 2.2". SoS gave no warnings. Finished this plate. Cartridge 8, plate 2195, seguefaint118. Guide stars found on gotoField using small offset (could see the glow of guide star just outside of one of the fibers). 08:58Z - Pre-Calib. 09:05Z - 20-minute exposure. 09:28Z - 20-minute exposure. 09:55Z - 20-minute exposure. 10:18Z - 20-minute exposure. Seeing: 1.5" - 1.9". SoS gave a whopping fiber warning (#94). 11:00Z - Enclosure on, doors and louvers closed, fans off. 06:10Z - PT morning twilights. endNight rejoiced. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6817 22:46Z 23:08Z 100 O -79.06 -73.45 52 bias ---=== 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; bias (44852), flat (44856), arc (44857), science/plate 2742 (44858), science/plate 2747 (44867), science/plate 2195 (44871).
