APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Friday March 27, 2009 (MJD 54918) ---=== OBSERVING TEAM ===--- Dan Oravetz Audrey Simmons ---=== OBSERVING PLAN ===--- Science! ---=== OBSERVING SUMMARY ===--- We observed the following plates in photometric, but rather poor seeing conditions: Cart 4, plate 3294 (FINISHED) Cart 3, plate 3293 Cart 6, plate 3295 (?) Cart 5, plate 3308 Connie, would you mind looking at the total gathered signal on plate 3295 and let us know if it is done yet? There were a lot of exposures where SOS displayed r1 camera values less than 2, but the other cameras show more 'typical' values. This plate has been observed for about 16200 seconds so far. ---=== OBSERVING LOG ===--- Afternoon: ---------- All systems checked and are working properly.
