APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday October 10, 2007 (MJD 54384) ---=== OBSERVING TEAM ===--- Audrey Simmons (swing) Howard Brewington (observer) Viktor Malanushenko (observer) ---=== OBSERVING PLAN ===--- SEGUE & Supernova Science! ---=== OBSERVING SUMMARY ===--- Although we had clouds, rain, and/or high humidity at the start and end of the night, we were to do some superNova imaging in the middle with run #7047 (-178.8 to -139.4 including the ramps) ---=== OBSERVING LOG ===--- Afternoon: ---------- Set spectrographs for 11C (see problem section for details). Note that the filter wheel purge gauge for the PT is running a little low (it is a 9psi instead of 10psi). It is the guage that is right next to the ball/bubble vertical gauge. Didnt start ventilating because of nearby storms. Night: ------ 02:00Z We had clouds over the site, and rain to the near west as twilight ended. So, we waited for better conditions. 06:14Z Clouds and humidity decreased; we opened doors/louvers and turned on fans. 06:45Z We still had lots of lightning south of the site; therefore, we do not want to mount the imager at this time. 07:50Z Pulled enclosure, topped off spectro dewars, checked top/bottom balance, and did a test slew to check fiducials. 08:15Z goDrift on 82 N with Run #7047 at -startLambda 179. Skippy was good from the start: THETAF = 0.0094 degrees, 33.89 arcsec muErr: -7.5", nuErr: -1.2" Focus was in spec at frame 20. Seeing was ~1.4" as reported by seeingRun. 08:29Z Start of ramp with frame 25 at lambda 178.0, but we were most likely good from frame 20 as focus converged. 08:34Z Start Science with frame 38 at lambda 176.0 10:30Z Seeing decreased to ~2.0" as reported by seeingRun. 10:56Z Humidity increased to about 84% 10:59Z We ended the drift and quickly closed. The drift was stopped at frame# 281 and lambda -139.4 11:12Z On-telescope bias in darkened enclosure; it was run# 7048 ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments
