APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Sunday January 25, 2009 (MJD 54857) ---=== OBSERVING TEAM ===--- Audrey Simmons Dmitry Bizyaev Steph Snedden (afternoon) ---=== OBSERVING PLAN ===--- 25 Jan 2009 54857.0 0.00 BOSS/SEGUE 10.7 hours ---=== OBSERVING SUMMARY ===--- Added signal to plates 3198 (c. 6), 3226 (c. 6), and 3170 (c. 4). Stripe 73 S observed from lambda 176 to lambda -153 (including ramps). Moderate seeing with very rare spikes over 2" below 2.5". A tiny cloud passed through the field (it touched probably 1-2 frames) between frs. 120 - 127. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems noted during afternoon checkout. No change made to spectrograph focus. No data deleted from sdsshost2 / sdssfiles1. 23:35Z - Ventilation started Night: ----- replaced spectro dewar replaced imager dewar 00:25Z enclosure off. 01:24Z gotoField with cart. 6 plate 3198 GSOGTF First guider frame: gimg0263.fits 01:35Z precal 01:41Z science 1500 -> 1800 sometimes really bad seeing, > 3" Since r1 = 1.4, we don't count this exposure. 02:14Z science 1500 this one is better and squizzed throu the "2.0" criterium. postcal --- Seeing improves significantly. We are mounting the imager. Seeing is ... 03:00Z scanStripe 73 S. 03:07Z goDrift, run 7932. In-focus from frame 16.

Seeing is so so. 08:42Z postcal This plate is finished. -- 08:48Z cart 4 plate 3170 is mounted GSOGTF (to the very corner) First guider frame: gimg0989.fits 08:57Z precal 09:04Z science 1800 some clouds in the field Wind gusts are getting worse. Also, we have sclouds in the field and loose efficiency. We managed to move telescope to the stove position (it is almost down the wind) with the dome stay opened. 10:39Z wind went down below 35 mph in gusts. gotoField with cart. 4. 10:41Z precal 10:47Z science 1500 -> 1800 Clouds, low efficiency during the exposure 11:20Z science 1800 signal is really poor, most of the exposure was in clouds. It is marked as BAD. 11:53Z midcal 11:59Z science 1800 - aborted, no signal because of clouds. Wind is rising, and the sky is completely overcast. We decided to close. 12:15Z dome closed. Ventilation switched to the internal one.
