APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday January 31, 2008 (MJD 54497) ---=== OBSERVING TEAM ===--- Dan Oravetz Dmitry Bizyaev Shannon Watters (afternoon) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Added signal to cart. 9 plate 2865 Got a problem finding guide stars for cart.7 plate 2912 (too faint guide stars??) Finished cart. 5 plate 2885 and cart 4 plate 2915 Added signal to cart. 3 2659. Second part of the night was in clouds. They really hurt observations close to the morning. ---=== OBSERVING LOG ===--- Afternoon: --------- All systems checked and working. There were no problems with chip 33 during the imager bias (it's colder today). Imager shutter pressure is 76 psi (spec is 80 psi). Spectro focus set for -6.3C Night: ----- 00:40Z opened dome Cartidge 9 is on, plate 2865 01:15Z GSOGTS. Focus loop. 01:38Z pre-cal 01:46Z science 1500 altitude is low, efficiency is rather bad 02:14Z science 1500 --> 1800 same about the efficiency postcal Temperature goes up, it's already -1C. Moving pistons in both sp1,sp2 by +3000. 03:03Z Cartridge 7 plate 2912 mounted. We see just a few guide stars in the field, even with 25 sec guider exposure. Focus loop doesn't help much. Some more guide stars are seen (up to 9) but guider doesn't understand it. Number of g. stars changing from 3 to 8 from exposure to exposure. All other parameters are ok. Seeing is around 2.5, guider shows efficiency 110%. Something is wrong with this cartridge. We decided to mount #4 instead. 03:33Z Cartridge 4 plate 2915 mounted. GSOGTF. All guide stars show up. 03:42Z precal 03:49Z science 1800 04:22Z science 1800 04:55Z science 1800 midcal 05:37Z science 1800 06:10Z science 1500 06:38Z science 1500 --> 1200 postcal 07:11Z cartridge 5 plate 2885 mounted GSOGTF 07:17Z precal 07:24Z science 1200 07:47Z science 1200 08:10Z science 1200 --> 1500 postcal 08:48Z Cartridge 3 plate 2659 mounted GSOGTF precal 09:00Z science 1200 09:23Z science 1200 10:14Z science 1500 --> 1800 10:47Z science 1800 low s/n because of clouds.
