APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday May 21, 2004 (MJD 53147) ---=== OBSERVING TEAM ===--- Dan Long Jurek Krzesinski Mike Harvanek (swing) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We finished two plates at the start of the night waiting for the moon to set (3 1611, 1 1676). Skies were clear all night and the seeing was good, so once the moon set we switched to imaging. Out of focus images showed significant coma in dewars 5 and 6 (run 4644). We prepared to adjust collimation, but found after homing and relaxing the primary that the coma was much reduced and the squashed looking images were less so(run 4645). We decided not to make any changes. We then imaged 22 N between lambda 10 and the end of the stripe (already discounting ramps), which took us to the end of the night (run 4646). ---=== OBSERVING LOG ===--- Afternoon: ---------- Spectro collimation was adjusted. Details are in the Problems section. New nominal mirror values were saved. Night: ------ 01:55Z Doors Open, Fans On 02:05Z Enclosure Open Cartridge 3 1611 17.4 15.0 18.0 16.9 Done 02:24Z gotoField guidestars on slew (no calib offsets). 02:37Z Trying multiGuiderDark again, while waiting for twilight. TCC connection closed due to timeout on one of the gcam doDark 30 commands. Trying a second time. Temperature about 15 C now. 03:04Z preCalib 03:12Z First science 26911 Done in three exposures. 04:01Z instChange Cartridge 1 1676 17.4 13.9 19.9 16.2 Done 04:04Z gotoField 04:14Z preCalib Lost a little time due to an errant doNextScience started out of order. 04:27Z First Science 26916 Done in three exposures. 05:12Z instChange Switching to imaging now that the moon has set. 05:26Z scanStripe 22 N -7 Run 4644 Donuts looked significantly comatic in dewars 5 and 6, especially in r. We decided to do a proper collimation check. 05:42Z scanStripe 82 N 35 Run 4645 engineering Homing and relaxing primary and homing secondary seems to have removed the majority of the coma, so no changes were made. Frame 41 is -300 from focus. Frame 46 is +300. There are still image distortions, most pronounced near the top of dewar 6. Donuts currently on sdsshost in /data/photo/optics/53147. scp to same dir on phoenix started at the end of the night. 06:28Z scanStripe 22 N 6 Run 4646 science In focus and skippy happy from the start (lambda 7) Run went to the end of the survey area finishing at frame 399 (lambda 65) at the start of twilight. 10:28Z On telescope bias Run 4647 Bias 11:55Z endNight rejoiced. Photo tapes in omaha. ---=== IMAGING RUN SUMMARY ===--- Run Time Stripe Lambda Last Flavor Comments Start End Begin End Frame -------------------------------------------------------------------------
