APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday April 20, 2006 (MJD 53846) ---=== OBSERVING TEAM ===--- Days: Howard Brewington Observers: Stephanie Snedden, Viktor Malanushenko Visitors: Victor Leger ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- To start, we got spectroscopy, plate 2077 (cartridge 5) - was DONE. The seening was good, dust was under new criteria, sky was completely clean and we start imaging observations. We got some data on Segue 1260 S strip, then got data on hole area 23 S and on Segue 1062 S strip. More information in to section ImagingDetails. After moon rise we has continue spectroscopy observations. Plate 1849 (cartridge 9) was DONE by three exposure. Plate 2247 (cartridge 4) - special plate: has obtained 5 exposure 120sec each. We wented to twilight. We send e-mail to Brian : ascked check it before declared as done. The dust was approximately 33100, by that, please: mirrow should be cleaned. ---=== OBSERVING LOG ===--- Afternoon: ------------ Found a few problems during the afternoon checkout. The noise bars are still present in the astro/photo monitors. Steph took some images of noise with her digital camera, but it will be a few days before she will be able to process the pictures. I noticed that the gearHead of the south-east Az-motor is leaking oil on the floor of the lower enclosure. I checked spectro focus/collimation and adjusted to ~8-degree C. I noticed while doing a set of preCals that the SOP session returned the many "NaN" as displayed below: Starting Flat field 0 (press cntrl-C to abort) Flushing charge for 15 sec appending BEGIN Exposure is paused; 10s of data were taken appending END EXPOSURE TIME is: 10 2006-04-21 00:13:26Z: NaN value for SPA in spectro fits header 2006-04-21 00:13:26Z: NaN value for IPA in spectro fits header 2006-04-21 00:13:26Z: NaN value for IPARATE in spectro fits header 2006-04-21 00:13:26Z: NaN value for AZ in spectro fits header 2006-04-21 00:13:26Z: NaN value for ALT in spectro fits header 1145578374 1145578402 Closing Flat Field Screen 4 Ne and 4 HgCd lamps are on Starting Arc lamp exposure 0 (press cntrl-C to abort) Flushing charge for 15 sec appending BEGIN Exposure is paused; 2s of data were taken appending END EXPOSURE TIME is: 2 2006-04-21 00:15:43Z: NaN value for IPARATE in spectro fits header 1145578520 1145578540 00:50Z Door and louvers open, fans on (dust=3k).
