APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Saturday February 25, 2006 (MJD 53792) ---=== OBSERVING TEAM ===--- Kaike Pan Howard Brewington ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- It was partly cloudy, and seeing was not good. Under the conditions, we finished five plates: 2213, 2221, 2355, 2119, 1809. and got signals on other three plates: 2418, 2403, 2205. Problem: There were high frequence noise while opening flat field screens. ---=== OBSERVING LOG ===--- afternoon: spectrograph focus was checked, and no adjustment made. 23:45Z Fans on, lovers and east door open, west door craked. Night: ------- 01:00, enclosure off. There were high frequency nosies while flat field scrrens were opening (it seems that the nosies came from screens above counterweight #2). 01:45Z cart 8, plt 2418 (chunk). stars on goto field. sky is cloudy at the momment. Seeing is getting worse, and reaching 2.5, then 3.0". Two 25 min exposures gave us a minimum S/N^2 of 4.8 on r1. The second one has r1 S/N^2 of 2.0. Since this is for 25 min exposure (not for 15 min), we are not very sure if this data is usuful or not. Can somebody take a look, and give us a feedback? Thanks. The plate is NOT done. 03:00Z cart 4, plt 2403 (sequefaint). Stars on GTF. We acquired 4 25-min exposures on this plate, but the last one is bad. The minimum total S/N^2 is 8.9 (on r1). The plate is NOT done. 05:15Z cart 5, plt 2213 (chunk). stars on GTF. Seeing improved since 2nd exposure, to about 1.4". The plate is DONE with a total exposure time of 4200s. 06:50Z cart 3, plt 2221 (chunk). Stars on GTF. The plate is DONE with a total exposure time of 2700s. 08:05Z cart 9, plt 2355 (chunk). Stars on GTF. The plate is DONE with one 20-min exposure, pluse signal collected on MJD 53789.

When getting the offsets and focus for this cartridge, the plate number did not came out right, it gave plate number 0. We got three exposures on this plate, but the last one which is in twilight is not good. The plate is NOT done. 12:50Z endNight rejoiced.
