APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 6, 2005 (MJD 53528) ---=== OBSERVING TEAM ===--- Steph Snedden (swing) Mike Harvanek Dan Long visitor: Mark Rabbage (BBC) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We imaged all night tonight. Run 5395 got the 18 S "hole" Run 5396 finished 1020 N (if the bad seeing right at the end is accepted - see log for details) Run 5398 got 290 N from 252.5 to 272.5 (seeingRun mu) ---=== OBSERVING LOG ===--- Swing shift: ----------- No spectro focus adjust needed (based on predicted lows for tonight). The rest of swing shift was without problems. Jon pointed out that the pressure on the imager dewar dropped at the last fill and did not come back up. We went to see that the in-line N2 valve was open (it was) and that there were no leaks (there weren't). The gauge on the 180-l dewar was approx. 25 psi, but we don't know how much to trust it. We will keep an eye on the pressure. Night: ------ 02:25Z Enclosure Open Starting out with imaging. The only things available at the start of the night are the "holes". Since we've got half an hour after twilight before the first available SEGUE stripe, we will do one. Run 5395: 18 S -8 to -6 excluding ramps ------------------------------------------ Seeing, and skippy good from the start. 03:51Z Twilight at frame 31 lambda -11.9 (start of ramp) 03:06Z Start of science frame 57 lambda -8 04:14Z Start of ramp frame 71 lambda -6 04:25Z End of run frame 88 lambda -3.5 Run 5396: 1020 N 242 to 277 excluding ramps ---------------------------------------------- 04:38Z Start of ramp frame 10 mu 238.8 Focus, seeing and skippy good from the start. 04:55Z Start of science frame 32 mu 242 skippy would not run on data past frame 175 too many stars? run out of catalog? seeingRun goes from good to acceptable at frame 188 mu 265.5 seeingRun goes from acceptable to bad at frame 230 mu 271.7 Median seeing got up to about 1.8 arcseconds by the end of science and went over 2.0 during the ramp. Given that this stripe goes past -20 Dec putting the altitude below 37 degrees even at transit, I'm not sure it is ever going to be better. 07:13Z end of science frame 265 mu 277 07:25Z end of run frame 281 mu 279.5 Run 5397: 290 N 252.5 to nowhere ignore ------------------------------------------ 07:35Z start of ramp (seeingRun 250, tccmon 255) frame 10 Focus, seeing, skippy good from the start... but not for long Seeing goes bad a few frames in and stays there for 30 frames before coming back down. Ending drift and starting again. Run 5398: 290 N 252.5 to based on seeingRun and excluding ramps ------------------------------------------- For the third time tonight, scanStripe has issued the slew 3 times in a row before tracking. 08:00Z start of ramp (seeingRun 250, tccmon 255) frame 10 Focus, seeing, skippy good from the start 10:03Z start of ramp frame 211 (seeingRun 281, 272.5 tccmon) 10:14Z twilight frame 232 (seeingRun
