APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Wednesday June 28, 2006 (MJD 53915) ---=== OBSERVING TEAM ===--- Days: Dan Long Night: Steph Snedden Elena Malanusheko Shannon Watters ---=== OBSERVING PLAN ===--- Award winning science! ---=== OBSERVING SUMMARY ===--- The humidity was fluctuating around 85% and the sky was cloudy at the beginning of the night so we didn't open until 06:42Z. We finished 2 plates (2203, 2545). We had a problem with MCP so we did a hard reboot. This cost us about 45 minutes (see problems). Accumulated dust was very low - dust count was good based on the old criteria. The mirror doesn't need to be cleaned. ---=== OBSERVING LOG ===--- Afternoon: ---------- No problems with the afternoon check, other than an "unavailable" id6 (ICC id6 is not available ( Bad ICC)). Rebooted photo 2 crate and all was well. Spectro focus was checked but not changed, best focus about 11-12 C. See problems section for details. PT dewpoint sensor retuned today. Dewpoint reading correctly again. High humidity yet again prevented any late day ventilation. Night: ------ 06:55Z Cart 1, plt 2203, tile 1587, chunk116. Previous S/N: b1=11.6. We had a problem slewing to field (see problem section). NGSOGTF; FK5 used with an alt offset of 10. Plate finished (exposure: 900). 08:24Z Cart 8, plt 2545, tile 8215, seguefaint147. Previous S/N: b1=23.5. NGSOGTF; FK5 used. The lowest S/N is 49.8 on r2. We declared the plate done because we need another end of night plate. (exposures: 900, 1200, 1200, 120, 1500). 11:19Z endNight rejoiced.

We didn't see it cross any alt fiducials. Tried forcing it to accept the fiducials but to no avail. Steph went out to the telescope; when she tried to slew using the TCC the telescope did not move, however it moved using the MCP. She tried a TELSTOP then TELRUN but that didn't work. Eventually we had to do a hard reboot of the MCP and that fixed it. While slewing we heard the west-side bump panel on the dog house dragging and found a rock wedged between it and the floor. We're not sure if that caused the problem because it didn't show up in the interlocks.
