APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday May 8, 2006 (MJD 53864) ---=== OBSERVING TEAM ===--- Observer: Howard Brewington Support: Kaike Pan ET crew: Jian Ge, Scott Fleming ---=== OBSERVING PLAN ===--- ET Sience! ---=== OBSERVING SUMMARY ===--- Another photometric night. Seeing was < 1.5" for all of the observations. Dust was ~3K, so dust/hours = about 33K. Should the mirror be checked? We finished all eight ET plates. ---=== OBSERVING LOG ===--- Afternoon: ----------- No problems found during the afternoon checkout. Night: ----------- 02:05Z Cart 08, Plate 8024. Found the field with Fk5 in bright twilight. Dust=3.1K at start of exposure. Seeing = ~1.5" during exposure the 50-minute exposure. Dust=2.9K at the exposure's end. 03:42Z Cart 09, Plate 8025. Found the field with Fk5. Seeing =~1.6" and dust=2.9K durig the 50-minute exposure. 04:47Z Cart 04, Plate 8026. Found the field with offsets from last night's observation, i.e., cleared offsets and did A=-9 and D=-2. Seeing = ~1.2" and Dust=2.9K at the start of the 50-minute exposure. 05:50Z Cart 06, Plate 8021. Found the field with Fk5. Seeing=~1.5 and dust=2.9K during this 50-minute exposure. 06:50Z Midnight cals 07:06Z Cart 07, Plate 8022. Had some trouble finding the guide stars. I even tried for a Fk5 with a two-lap spiralPattern in fiber 10 without any luck. Finally, I cleared the offsets again, used fiber 11, made a guess of the needed offset, and found the Fk5. Seeing for this 50-minute exposure was ~1.3" and the dust=2.8K. 08:22Z Cart 02, Plate 8027. I had guide stars on goToField this time. The seeing was ~1.2" and the dust=3.2K during this 50-minute exposure. 09:29Z Cart 05, Plate 8029. I had guide stars on goToField. The seeing was ~1.1" and the dust=2.9K during this 50-minute exposure. 10:25Z Cart 03, Plate 8028. Guide stars on goToField. The seeing was ~1.1" and the dust=2.9K during this 50-minute exposure.
