APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday June 25, 2009 (MJD 55008) ---=== OBSERVING TEAM ===--- Kaike Pan Steph Snedden ---=== OBSERVING PLAN ===--- SegueScience! ---=== OBSERVING SUMMARY ===--- Clouds and a brief rain shower during first half. During second half we obtained useful signal on plate 3478 and finished plate 3141. The spectro dewar will need to be swapped out during the day. Russell installed a new version of the TCC during the day. We had no operational problems using it during the night. We took several flats during the night as part of routine operations with the newly installed flat field lamps. Hopefully these will be enough to meet Kyle's request, so the lamps can be changed back to the old ones during the day. ---=== OBSERVING LOG ===--- Afternoon: ---------- Got a warning in SOP about not being able to connect to sp1's cameras when I started the afternoon calibrations. I did a grabInst -drop, then re-grabbed the instruments, and all was well. No change made to spectrograph focus. No data removed from disk 01:15Z - Started ventilation Night: ----- Clouds formed at sunset - enough that we delayed opening, but kept the ventilation on. 04:25Z - Surprise showers. Closed doors, ventilation off. 05:25Z - Started ventilation again 06:16Z - Opened enclosure 06:26Z - Cartridge 5, plate 3478 - SEGUE April 09d -------------------------------------------------- Orographic clouds started reforming just after we opened, of course. Needed an FK5 to find the field (FK5 was on the edge of fiber 10). Obtained two useful exposures while battling clouds, but the plate is not yet done. 07:07Z - Pre-cal (S/N)^2 accumulated for plate 3478 Attention: the script does not count test or bad exposures ---- logfile-55007.html ---- ---- logfile-55008.html ---- --------------------------------------------------- MJD b1 r1 b2 r2 Texp Sum --------------------------------------------------- 55007 7.7 5.7 8.9 5.9 1500.0 28.2 55007 8.1 6.5 9.4 5.7 1801.0 29.7 55007 0.0 0.0 0.0 0.0 483.0 0.0 55008 3.8 2.8 4.8 2.7 1800.0 14.1 55008 5.5 3.7 6.0 3.1 1800.0 18.3 --------------------------------------------------- Total: 25.1 18.7 29.1 17.4 7384.0 --> 90.3 Total when ALL b,r values > 2.0: 25.1 18.7 29.1 17.4 6901.0 --> 90.3 (limit=156.5) --------------------------------------------------- 08:45Z - Cartridge 6, plate 3141 - SEGUE Aug 08d ------------------------------------------------ Needed an FK5, partly because of clouds.
