APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday August 18, 2006 (MJD 53966) ---=== OBSERVING TEAM ===--- Swing: K. Pan Night: Howard Brewington V. Malanushenko Support: French Leger Dan Long ---=== OBSERVING PLAN ===--- Science, but first the pointing model has to be done. ---=== OBSERVING SUMMARY ===--- Rain and clouds again tonight; we never opened. R1 seems to be working okay now; see log for more details. Spectro auto-fill is not working and must be done with manual switches; see log. There's a problem with the mirror numbers; see Mirror Section. I sent Kaike an email about this problem. ---=== OBSERVING LOG ===--- Afternoon: ---------- Many thanks to French and Dan for their hard works on cleaning the red camera of SP1. It was installed to spectrogaph backat 7:30pm. After getting the camera back, we mounted cartridge 5 to check the focus, then the plan is to check the camera using the sparse-plugged plate, cartridge 4. Spectrogram focus checked and adjusted: Sp1 piston moved by 4700, and blue ring moved by 10.9 degree. Since the r1 camera was took apart before being cleaned, required adjustment is not surprising. The best focus is at about 15 C. Night: ------ 01:43Z Clouds and high humidiy at sunset. 03:50Z With the r1 camera remounted and properly cooled, we mounted cart 04 and did the sparse-plugged plate tests again as described below. 40446 bias 40447 10s flat 40448 50s flat 40449 200s flat 40450 40s arc 40451 180s arc 40452 bias 40453 bias 40454 40s arc 40455 180s arc The first bias (#40466), detailed below, was reported by SOS as good.

The bias levels of r1 were likewise compared to the other cameras, and the levels were good. Next, we looked at the images of the flats and arcs. And, they were compared to the flats and arcs of the other cameras. We think that they all looked okay but feel Craig should also have a look to make sure. 05:33Z After the sparse-plugged plate tests, we mounted, connected, and tested the engCam. It did take an image. We also rebalanced the telescope. endNight finished and was happy. The spectro auto-fill is not working, or should I say it's working too well. In other words, it fills much too often. So, we turned it off, and it will need to be filled with the manual switches. It was last filled at 4:00 a.m. (10:00Z). Norm will be in tomorrow afternoon (Saturday) for the next fill.
