APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday April 5, 2008 (MJD 54562) ---=== OBSERVING TEAM ===--- Steph Snedden (observer) Elena Malanushenko (observer) Dmitry Bizyaev (dayshift) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- It was photometric for 2-6:30, and some clouds after that. We have finished 3 plates 2955 (cart 2), 2920 (cart 6), and 1834(cart 9). We also got some initial signal on plate 2876 (cart 3). Spectro dewar needs to be changed after one morning filling. We noted some not taped leds on the outside part of sp1 and will tape them tomorrow. We do not think it affected the observations. The most of night we were working from generator power and it did not get any problems. Dust was in range 2.5-3.5K so we got 30K integrated dust counts. ---=== OBSERVING LOG ===--- Afternoon: ---------- ntp_check ok iccSoundOff ok imager bias ok spectro bias ok idl> apo_plotbias, 51640 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00051640.fit -6.0 -4.1 -2.8 2.4 6.9 8.7 10.2 sdR-b2-00051640.fit -7.8 -5.7 -4.4 0.8 7.0 8.2 10.7 sdR-r1-00051640.fit -7.8 -5.7 -3.8 1.2 7.2 8.4 10.2 sdR-r2-00051640.fit -8.1 -6.0 -4.8 0.5 6.6 7.8 9.8 Specto collimation should be good for +5C ambient (with cartridge 9). Cartridge 3 mounted. Ventilation started at 01:05Z. Delayed due to high dust count. Night: ------ 01:30Z enclosure is off. Strong wind up 30 mph, T=7C, clear and photometric, no Moon. Unfortunately, seeing is bad. Dust is 2500-3500 at the time of the opening. Cart 3, plate 2876, SegueFaint User FK5 to find the stars, but possible as it was too bright outside yet. T=6.6C, foc=0. The alt is 27. Seeing is up to 3". 02:34 preCalib 02:46 science 1800. The seeing is up to 3.0 and so the efficiency in range 30-40%. At 02:50 the utility power was off. We was switched to generator. We lost the guider stars and found out that all axises are on brakes. Paused the exposure, cleared brakes, went FK5 and to field again, and resumed this exposure. Called to Mark, he said to continue the observations and the power system will switch back automatically when the quality of power will be sufficient. 03:23 science 1800 03:56 postCalib 04:04 science 1500 We obtained 6.9 (s/n)^2.
