APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 27, 2010 (MJD 55255) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Steph Snedden Kaike Pan (afternoon) Jim Gunn (PU) Connie Rockosi (UCO) ---=== OBSERVING PLAN ===--- MARVELS Science! ---=== OBSERVING SUMMARY ===--- Thick clouds all night. Jim and Connie continued spectro camera work. Craig issued hundreds of biases, presumably to tickle the dropped pixel problem. Replaced bad flat field lamp. Left the burned out bulb on Wendell's desk. No science data, unfortunately. Telescope left at zenith for Jim and Connie with fill line extensions hooked up. ---=== OBSERVING LOG ===--- Afternoon: ----------- All actors, systems, and the telescope were checked. No problem to report. Since the weather does not look good in the evening, and forecasting and satellite images both indicates that weather will be bad for at least the first half tonigh. We let Connie continue her test to check Boss spectra line-dropping issue. So no fiducial crossing check, no boss dark, no gcamera dark this evening. Compressed 20 mjd (54436-54455) in /data/mcptpm. Put on LN2 fill line extensions so Connie cann work without having to stop to force a fill. Night: ----- Replaced burned out flat field lamp from the SW corner of the telescope (above sp1). Note that the Holloman baffle is only held in by one screw, and the second screw appears to be misaligned. The one screw is secure, though, and it appears we've been operating this way for some time. At this point, we waited on clouds while Connie and Jim continued working on the spectrograph camera electronics. 07:05Z - Still cloudy, but Jim & Connie's work was done for the night, so we started ventilation, optimistically. Craig took hundreds of biases after the camera work was done. We had some hope that the clouds would dissipate, but they never did. 11:55Z - Ventilation off. Doors closed. endNight finished. ---=== SPECTROSCOPY DATA SUMMARY ===--- Summary Checked (y/n): QA Procedures Done (y/n): UT Exp Time flavor comment (S/N)^2 totals ========================================== b1 r1 b2 r2 ---=== TELESCOPE OFFSETS AND SCALE I ===--- Time Instrument Az Alt Rot Scale pos offset pos offset pos offset ------------------------------------------------------------------------------ ---=== TELESCOPE OFFSETS AND SCALE II ===--- ---=== FOCUS LOG ===--- setmir piston Temp Wind Time Inst scale M1 M2 Foc Az Alt (C) MPH Dir filt fwhm ------------------------------------------------------------------------------ ---=== WEATHER LOG ===--- Wind Time Temp F Dewp F MPH Direction Dust DIMM Sky 22:35Z 41 7 18 226 (SW) 501 - cloudy 23:08Z 40 3 11 218 (SW) 498 - ' 23:41Z 40 2 16 192 (SSW) 532 - ' 00:14Z 39 5 16 205 (SSW) 557 - ' 00:47Z 38 7 16 186 (S) 561 - ' 01:20Z 38 8 17 197 (SSW) 588 - ' 01:53Z 39 8 18 192 (SSW) 564 - ' 02:09Z 38 10 21 197 (SSW) 616 - ' 02:42Z 39 8 13 184 (S) 670 - ' 03:15Z 35 15 17 175 (S) 663 - ' 03:48Z 35 15 17 151 (SSE) 739 - ' 04:21Z 34 16 16 160 (SSE) 584 - ' 04:54Z 34 16 20 161 (SSE) 598 - ' 05:27Z 34 16 18 154 (SSE) 609 - ' 06:00Z 33 16 19 161 (SSE) 559 - ' 06:33Z 36 15 22 174 (S) 617 - ' 07:06Z 36 15 16 185 (S) 748 - ' 07:39Z 37 17 24 187 (S) 775 - ' 08:13Z 36 17 25 195 (SSW) 811 - ' 08:45Z 37 17 29 182 (S) 952 - ' 09:18Z 37 15 16 195 (SSW) 944 - ' 09:51Z 37 16 21 186 (S) 947 - ' 10:24Z 37 15 23 199 (SSW) 921 - ' 10:57Z 36 16 22 181 (S) 886 - ' 11:30Z 35 17 24 185 (S) 876 - ' ---=== TELESCOPE STATUS ===--- 07:05Z - Started ventilation. 11:55Z - Ventilation off.
