APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 26, 2009 (MJD 54978) ---=== OBSERVING TEAM ===--- Alaina Shelden Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night was mostly lost due to clouds and humidity. We obtained some signal on cart 2, SEGUE plate 3428. Please have a look at the cartridge bay manipulator arm. It is very noisy. ---=== OBSERVING LOG ===--- Afternoon: ---------- Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 119G 16G 89% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 738G 133G 85% /data sdssfiles1p:/data1/data 1.5T 594G 799G 43% /files apo_plotbias, 61418 Filename 02% 05% 10% 50% 90% 95% 98% ------------------- ------ ------ ------ ------ ------ ------ ------ sdR-b1-00061418.fit -5.5 -4.2 -3.1 2.4 7.9 9.2 11.2 sdR-b2-00061418.fit -8.1 -6.3 -4.3 1.1 7.2 9.6 10.9 sdR-r1-00061418.fit -6.4 -5.1 -3.4 1.6 7.6 9.6 11.6 sdR-r2-00061418.fit -7.6 -5.5 -4.0 1.8 8.1 10.2 12.3 Checked collimators, but left them set for ~12C. 01:10Z - Began ventilating. No problems during checkout. Night: ------ 01:58Z - Sunset. We did not open because of nearby radar returns. 03:15Z - Clouds came in. Mostly cloudy. 03:40Z - Evening twilight. 05:35Z - Clouds broke. Opened enclosure. 05:51Z - goToField cart 2, SEGUE plate 3428. Used fk5 to find field. 06:09Z - Precals. 06:17Z - 30 min exposure. Seeing 2.5" 06:50Z - 30 min exposure. 07:01Z - endStare -abort. Very thick clouds came in. We aborted the exposure and moved the telescope to 121,30 with the FF pedals closed. 08:07Z - goToField. Clouds thinned. Used fk5. 08:18Z - Precals. 08:20Z - Closed enclosure due to high humidity. Stopped ventilating. 10:05Z - Humidity dropped. Opened enclosure, began ventilating. 10:11Z - goToField. GSFOGTF. 10:19Z - 20 min exposure. Seeing 1.5" 10:25Z - Morning twilight. 10:42Z - Postcals. This plate is not done yet.
