APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday June 8, 2005 (MJD 53530) ---=== OBSERVING TEAM ===--- Steph Snedden (swing) Atsuko Nitta Dan Long Visitors: Jim Gunn (PU) Connie Rockosi (UCO Lick) Mark Rabbage (BBC) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Imaged most of the night. Filled the last survey "hole" on the list. Run 5408 34 N -5 to -4 Nearly finished 1062 N before clouds moved in. Run 5409 1062 N 247 to 261 Run 5410 1062 N 274 to 305 Switched to spectroscopy and got a couple exposures on plate 2185. We noticed on closing that the grade 2 nitrogen bottle in the rotating rack, was right near 500 PSI, and may need changing today. ---=== OBSERVING LOG ===--- Swing shift: ----------- Based on the predicted low temps for tonight, no spectro focus adjust was made. The rest of swing shift was uneventful, except for the arrival of Jim Gunn and Connie Rockosi. Trumpets and choirs of angels were heard.

Thin clouds approaching from the west, std dev now over 7 08:22Z Clouds reach where we are pointing Mu 307.5 Frame 250 Calling this the end of the ramp, making end of science Science End Mu 305 Frame 233 Ramp End Mu 307.5 Frame 250 08:35Z Satellite shows this to be a small patch of cloud. Given the dark skies and continued excellent seeing, we will wait for the patch of cloud to pass. 08:53Z Ending drift at frame 295 09:24Z Changing to spectroscopy. the clouds aren't leaving, at least not fast enough to get a useful imaging run in the time remaining. 09:39Z Cartridge 7 2185 seguefaint Guide stars on slew Putting off calibrations to twilight in hopes of getting two science exposures in first. Of course this means SoS won't show us signal from the exposures, but we won't reach S/N of 50 in two more exposures anyway. Got two 20 minute exposures and took a post cal in twilight. 10:45Z Enclosure Closed endNight running as this log goes out. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor
