APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Thursday June 1, 2006 (MJD 53888) ---=== OBSERVING TEAM ===--- Viktor Malanushenko Howard Brewington Mike Harvanek (swing) Craig Loomis (support) ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We opened late because of clouds. The guide stars of Cart 03, plate 2172 had uneven focus; see log section. We finished one plate (2193) and completed two exposures on plate 2167. ---=== OBSERVING LOG ===--- Afternoon: ---------- At approximately 23:56:33Z the telescope became unresponsive to track commands issued from the tcc. The error messages indicated a problem with the mcp (LAT 19). Craig Loomis was called and he had a look. According to Craig, the mcp was unresponsive for more than 20 min. Then it fixed itself and started responding again. Craig is continuing to look into the problem. Spectrograph collimation was checked but not adjusted. The collimation is currently set for a temperature of approximately 10 - 11 degrees C. Nothing else to report. Night: ------ We had clouds at sunset, so we waited. While we waited for better conditions, we enjoyed gourmetNite. Our gNite menu included the following items/entrees: Green salad Potato and sausage soup Lasagna Pizza Meat and veggie chili Chocolate, cream cheese, raspberry dessert. ------------------------------------------- 05:56Z Doors and louvers opened, fans on. 06:49Z Time of moonset. 07:25Z Enclosure off 07:36Z Cart 03, plate 2172 (chunk112). An Fk5 star was used to find the field. We could not start a science frame on this plate because of uneven focus across the guide stars. In other words, when the stars in the center of the saoDisply were in focus, the guide stars on the edge of the saoDisplay were donuts (and vice versa). And, although we did two focus sweeps, we could not find a proper focus. So, we decided to change to Cart 04. After Cart 03 was removed from the telescope, it was inspected. I noticed that a few of the fibers were not at the focal plane. Nearly an hour of time was lost to this problem. 08:22Z Cart 04, plate 2167 (chunk112). Guide stars on goToField. All of the guide stars were at the same focus on this plate. We completed two exposures before this plate expired for the night. 09:33Z Cart 05, plate 2193 (seguefaint118). Guide stars on goToField. Plate was declared done when tonight's S/N was added to previous night's; see below.
