APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday December 19, 2009 (MJD 55185) ---=== OBSERVING TEAM ===--- Elena Malanushenko Viktor Malanushenko ---=== OBSERVING PLAN ===--- Science! 19 Dec 2009 55185.0 0.23 00:20 11:26 BOSS 11.1 hours ---=== OBSERVING SUMMARY ===--- The first part of night was lost due to high humididy. We observed 3 plates: 3666, 3676, 3692 cart 12 plate 3666 DONE? We had problem with boss exposure pre-readout (see log and problem section). ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems, actors were checked and working properly. Cartridge 14, plate 3589, was mounted and collimations were adjusted, sp1 by -8648, and sp2 by -3228. 23:10Z: started ventilation. Cart 14 plate 3589 is mounted. Night: ======= It is clear and photometric but humidity is a little high now ~78% with difference ~3.2, 00:15Z High humidity, we closed door, louvers, stop ventilation. 01:02Z enclosure off 00:39Z High humidity, we closed door, louvers, stop ventilation. 05:11Z Humidity dropped down. 05:20Z enclosure off Cartridge 12 plate 3666 05:25Z gotoField 05:31Z hartman, 105352, 353: sp1> +2325, sp2> -3828 05:54Z - 08:09Z 8x900sec science : 105356 - 105363 06:12Z 2nd exposure was lost (files '*-00105357'): after exposure system was unable to readout it. The timer in BOSS GUI was cycling the command 'preread'. We made 'boss clean exposure' and lost the exposure.

The boss/sop could not reading it (see #2 in to 'problem' section) --"boss exposure status" show error message 10:26:23 .boss 7371 boss w text="exposureState timer does not add up (remain=-317.60 total=3.00)" 10:26:23 .boss 7371 boss i exposureState=PREREADING,3.0,0.0 We tried to save the exposure and ran "boss exposure abort" and "boss exposure readout". Finally we read the exposure on 20 min later after its integration was completed, files 105373. We compared it with previous science exposure files 105372 using DS9 and found them very similar.
