APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday October 10, 2005 (MJD 53654) ---=== OBSERVING TEAM ===--- Swing: John Barentine Night: Jurek Krzesinski Howard Brewington Support: Steph Snedden Visitors: Viktor Malanushenko Olena Malanushenko ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- 82N lambda 115 to -162.5 (excluding ramps) 79N with clouds and an az axis abort; see imagingDetails for more information. Could someone please check to determine if any of these data are usable. ---=== OBSERVING LOG ===--- Afternoon --------- Let the record show that the first snowfall of Winter '05-'06 occured today, Monday, October 10. Only six months 'til spring... No trouble during checkout today. Spectro focus numbers, as usual, are in the Problems section. Night ----- We noticed for the last two nights that the mcpMenu had a problem with the slithead doors status. The doors were once indicated as closed on the mcpDisplay when the doors were opened. And then last night, when both doors were physically closed, the mcpDisplay indicated that Sp1's door was open. 01:32Z We mounted the imager and did an on-telescope bias. After doing an on-telescope bias with the imager, we started with 82N; see imagingDetails for more information. We stopped 82N at 09:00Z and moved to 79N since the sky was photometric and 79N had a higher priority. We, unfortunately, had clouds appear about forty-five minutes into this scan. After about forty-five minutes of clouds, the sky cleared, so we continued scanning. 11:17Z We, then, had an Az-axis abort while scanning 79N; however, it was not a slip. In fact, we could not determine why the axis aborted. And, we are not sure if any of the 79N data is usable since we had clouds and the axis abort. Could someone please take a look at these data and let us know if all or part of 79N should be scanned again? See Problems Section for misc Watcher messages. endNight finished and was happy. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame
