APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday June 11, 2005 (MJD 53533) ---=== OBSERVING TEAM ===--- Steph Snedden (swing) Mike Harvanek Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We had clouds during the 2nd-half of the night but finished plates: 1811, 1709, and 1656. And, we completed one exposure on plate 2196 and one on plate 2184. ---=== OBSERVING LOG ===--- Swing Shift: ----------- No spectro focus adjust needed, based on the predicted night time temperatures. No problems during afternoon checkout. Night: --------- As we pulled the building at sunset, we accidentally dropped the eastside-enclosure-movement box, which caused the speed control switch to fall apart. We removed the box's cover and snapped the switch back together. However, this switch may need some additional "expert" attention. 03:37Z Cart 05, plate 1811 (chunk94). We had guide stars on goToField. Plate was finished in three exposures. 04:43Z Cart 07, plate 1709 (chunk87). We had guide stars on goToField. Plate was finished in three exposures. Although the moon is no longer a problem and the seeing is ~1.0," we did not switch to imaging because of approaching clouds west and south of us. 05:57Z Cart 04, plate 1656 (chunk82). We had guide stars on goToField. At 06:22Z, we started to see clouds on the IRSC. Plate was finished in three exposures. 07:15 Cart 03, plate 2196 (chunk115). We had guide stars after the offsets were cleared. The first exposure was okay; however, the second one was not because of cloud cover. So, we waited until plate expired for the night. 08:50Z Cart 09, plate 2184 (segue117). We had guide stars on goToField. Completed one exposure before morning twilight. 09:00Z Watcher reported an ion_pump problem (~2.0 utorr). 11:14Z The ion_pump was at 0.2 utorr. Misc. Watcher messages are in the Problems Section. endNight finished and was happy.
