APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday March 25, 2009 (MJD 54916) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We gathered one good exposure on cart 4, plate 3294 before the clouds came in. We remained closed the rest of the night due to high dust and heavy clouds. Dithered flats were successfully obtained on the second attempt. We also completed spectro biases and darks. ---=== OBSERVING LOG ===--- Afternoon: ---------- Filesystem Size Used Avail Use% Mounted on /dev/sda3 142G 117G 19G 87% / /dev/sda1 99M 30M 64M 33% /boot /dev/sdb1 917G 831G 40G 96% /data sdssfiles1p:/data1/data 1.5T 669G 724G 49% /files Spectro focus checked and left at 2-3C. No problems during checkout. 01:03Z - Began ventilating, but did not open right away because of high wind gusts (~40mph). Night: ------ 01:17Z - Sunset. 01:40Z - Opened enclosure to clear skies. Winds died down. 01:49Z - goToField cart 4, SEGUE plate 3294. Cleared the offsets and used a spiralPattern with an fk5 to find the field. 02:15Z - Precals. 02:22Z - 30 min exposure. Seeing 1.7" 02:41Z - Evening twilight. 02:55Z - Cals. 03:01Z - 30 min exposure. Lots of clouds. Low efficiency. We waited for the efficiency to rise before starting another exposure.
