APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday June 23, 2006 (MJD 53910) ---=== OBSERVING TEAM ===--- Days: Dan Long Night: Howard Brewington Jurek Krzesinski ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- The night lost due to the weather, we tried to get some exposures but all of them were bad. Enclosure door: The wellness of the 2.5-m enclosure's west door was checked tonight, and it still seemed a little unhappy when closing because of the increased noise. A bad motor bearing, perhaps? Cloud camera: During the early part of the night, while we had clouds, Howard aligned the tilt of the cloud camera to get the spider supports under the support masks of the software. Problems: --------- Dust counter is not working. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems with the afternoon check. Spectro focus was checked but not changed, best focus about 14 C. See problems section for details. PT dewpoint sensor dewpoint still showing a fairly constant value of zero when the 3.5m value is around 10 C. Temperature value still OK. Outside dust counter also decides one number is good for all time. It seems to be stuck at 1804. 01:15Z Doors Open, Fans On. Night: ------ We wated most of the night for clouds and hight humidity to go away. 08:07Z We mounted cart 9 plt 2534 and get ready to open if the clouds will get thinner a little more. 09:29Z Good enoguh to try. Fk5 used to find the guide stars. Efficiency is low, but we cannot say we didn't try to get some photons :). Thicker clouds arrived - 2 exposures did not get good s/n and were declared bad. 10:43Z endnight finished ok. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame ------------------------------------------------------------------------- 6222 21:38Z 21:48Z 100 O -54.36 -51.83 31 ignore ---=== IMAGING RUN DETAILS ===--- ---=== SKIPPY RESULTS ===--- Run Frame nFrames stars muErr muRms nuErr nuRms rot az el --------------------------------------------------------------------------- ---=== LTMATCH RESULTS ===--- Run Field nFields alt az nGood rowMean rowSig colMean colSig rot ------------------------------------------------------------------------ ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): yes QA Procedures Done (y/n): no.
