APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday November 17, 2008 (MJD 54788) ---=== OBSERVING TEAM ===--- Howard Brewington Dan Oravetz Steph Snedden (swing) Visitor: Demitry Muna (NYU) MARVELS: Nathan DeLee (UF) Jiang Peng (UF) ---=== OBSERVING PLAN ===--- BOSS/SEGUE & MARVELS Science! ---=== OBSERVING SUMMARY ===--- BOSS ---- We imaged 83 S (run 7812) from lambda = 130 (frame 48) to lambda = 149 (frame 175), including ramps. The seeing was marginal during this run (see log for specifics), so we would like to know as soon as possible whether this is useful since we're running out of time for catching the beginning of BOSS stripes. SEGUE ----- Added signal to cart. 2, 3133, with 2X1800-second exposures. MARVELS ------- cart. 9, 3076, fields A & B. cart. 8, 3075, field A. cart. 3, 3077, fields A & B. cart. 1, 3078, fields A & B. Other ----- The ODH siren was going off from at least 10:35Z until we closed. The metal plate that serves as the interlock preventing the Lindy cart from running over the fiber link seems to be broken. It is very loose compared to how we remember it being and it makes for a difficult time properly getting the hatch cover on and off. ---=== OBSERVING LOG ===--- Afternoon: --------- No problems noted during afternoon checkout. Spectro focus is set for expected beginning of night temp. of about 6 C. Removed MJD 54753, 54754 data from sdsshost2. The disk space is now: /dev/sdb1 917G 813G 58G 94% /data sdssfiles1p:/data1/data 1.5T 1.1T 348G 76% /files Night: ----- 23:55Z - Mounted the imager, unlatched the t-bars, moved couterweights to 730. 00:06Z - Sunset. 00:23Z - On-telescope t-bars unlatched imager bias. Run 7811. Taken in the enclosure with all of the lights off during twilight. BOSS imaging - 83 S ******************* 01:10Z - scanStripe 83 S 127. Altitude = 52 degrees. 01:13Z - goDrift. Run 7812. The focus was >100 steps off compared to the focus plot (which is usually pretty reliable), so we didn't get in focus until after ramp had started. We paused the focus loop and back-tracked so that we would start ramp in focus. 01:28Z - scanStripe 83 S 128. Altitude = 51.5 degrees. Restarted the focus loop. We tried running skippy and received errors that it could not find the FITS files. We restarted the teamster and then we had gang transfers and files were transferred normally again. astrom> skippy 7812 50 4 THETAF = 0.0129 degrees, 46.55 arcsec CT = 0.39596 arcsec/pixel SCALEF = 16.5978 arcsec/mm AMU0 = 315.1017 degrees ANU0 = -0.0005 degrees NCAT = 132 NSTARS = 106 AZ = 213.8120 degrees EL = 50.4488 degrees raBoreErr: -3.2", decBoreErr: -1.6" azErr: 3.2", elErr: -2.9" muErr: -3.1", nuErr: -1.7" 01:35Z - Start ramp.

The median seeing oscillated from 1.5" to as high as 2.3". On average, the seeing was ~1.9". Frames where the median value was > 2.0" roughly include frames 109-126, 134-143, 167-173, but often the median value was very nearly 2.0". We only imaged ~100 frames (~1 hour) because the wind was out of the east and the seeing was not showing signs of stablizing. We switched to spectro. 03:02Z - Dismounted imager, mounted corrector, mounted cart. 2, adjusted counterweights to 250 and checked telescope balance.
