APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Tuesday May 18, 2004 (MJD 53144) ---=== OBSERVING TEAM ===--- Jurek Krzesinski Pete Newman Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- Spectroscopy all night (nonphotometric). Plates with partial signal: 1610 (r2=12.3 S/n rest of the chips got s/n over 15) Four plates done: 1702, 1644, 1401, 1419 Nothing special to report. ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro collimation was adjusted. See the Problems section for details. Night: ------ 02:27Z Cart 3 plt. 1610 mounted at evening. Too bright at the moment, so we went for fk5 star. It was found after clearing offsets. We've got very good seeing (1.1"), but a star in fiber #2 is out of focus (fwhm=1.8"). As soon it got dark clouds arrived. A few first exposures were bad. Then we got 3 more exposures on improving sky and almost made it. Almost, but not done (s/n in r2 = 12.3, while in r1,b1,b2 > 15). While going to instChange position we've got: azimuth (correction for azimuth 624 is too large (2004-05-19 05:41:32Z sdssmcp): 2004-05-19 05:41:34Z ) on fiducials (-57, -42, -27), which fixed itself on fiducial: -12 (see problem section for timestamps). 05:49Z Cart 4 plt 1702 mounted. Stars on go to field. We found a hot pixel in fib 11 (see guider frame 1345) - fiber has been disabled from guidnig. (Temperature is now 16 C, so it's 8 C higher than the time guider darks were taken). Plate done. 07:08Z Cart 6 plt 1644 mounted. Stars on slew. Again we switched off fiber 11. Plate done. 08:17Z Cart 2 plt 1401 mounted. Stars on slew. Plate done.

Stars on gotofield. 09:23Z start guider did not return the image (last frame that worked 0210). We did stop guider, start guider and it resumed it's work.
