APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday August 21, 2004 (MJD 53239) ---=== OBSERVING TEAM ===--- Night: Howard Brewington Mike Harvanek Support: Pete Newman ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We are still having problems with hot pixels on the guider CCD; see log for details. Declared plates 1684, 1025, 1908, 1893, 1887, and 1888 done. And, we got some signal on one other. ---=== OBSERVING LOG ===--- Afternoon ------------ The only problem we had during the checkout was that the murmur server did not restart after sdssHost was rebooted. Spectro focus/collimation was checked and found to be within spec; see Problems Section for Coll_motor numbers. Night ------------- 02:20Z Cart 01, plate 1684 (chunk85). Guide stars on goToField. Plate was declared done when tonight's SN^2 was added to a previous night's; see below. MJD b1 r1 b2 r2 53238 8.9 6.1 8.0 7.6 53239 14.8 11.8 13.0 14.9 --------------------------- total 23.7 17.9 21.0 22.5 We ran over a little on the SN^2 on plate 1684 because SOS did not reduce our first exposure; we needed to do a sos_redo. 03:10Z While doing a long imager bias, we noticed the noise/herringbone in Dewar 01 had returned; we think it was frame 258 on Run 4787. 03:30Z Cart 04, plate 1025 (lowz45). Guide stars on goToField. This plate was of lower priority, but we finished it because of its existing signal and expiration date. Although we've done two sets of guider darks, we noticed that there is still a problem with hot pixels on the guider CCD. Consequently, guide fibers 11 and 02 were disabled during this exposure. This plate was declared done when tonight's SN^2 was added to a previous night's; see below. MJD b1 r1 b2 r2 53227 16.0 14.4 16.0 14.6 53239 22.3 20.6 22.7 20.5 ---------------------------- total 38.3 35.0 38.7 35.1 04:33Z During the second exposure (28227) of previous plate (1025), we got a "WRONG num of pix?" report in watcher: see Problems Section for messages. 05:05Z Cart 02, plate 1908 (segue98). Guide stars on goToField. Plate done in three exposures. 06:30Z Cart 07, plate 1893 (seguefaint98). Guide stars found with -7 and +4 offsetts. Fiber seven was disabled because there was no guide star. Three 20 minute exposures finished this plate. 08:00Z Cart 08, plate 1661 (seguetest83). No guide stars on goToField or found with the help of an Fk5 star. We had to use spiralPattern at the field to locate the guide stars. Two exposures were completed, but plate was not declared done. 09:00Z Cart 06, plate 1887 (seguefaint98). Guide stars on goToField. Plate was declared done when tonight's SN^2 was added to a previous night's; see below. MJD b1 r1 b2 r2 53238 18.4 14.8 19.0 17.9 53239 31.1 23.3 31.8 26.7 ------------------------------ total 49.5 37.6 50.8 44.6 10:00Z Cart 09, plate 1888 (segue98). Guide stars on goToField. Plate was declared done in three exposures. endNight finished and was happy.
