And, we got some signal (two exposures) on plate 2248 before poor seeing and high humidity became a problem. ---=== OBSERVING LOG ===--- Afternoon Checkout ------------------ The afternoon checkout was uneventful. The spectro focus was checked but not adjusted since it was in spec. Night ------------------ 02:15Z Enclosure off, fans on. 02:30Z Cart 07, plate 1799 (chunk94). We had to use spiralPattern to find an Fk5 star in bright twilight. Plate was finished with one exposure after adding tonight's signal to last night's; see below. MJD S/N^2 53555 12.5 53556 3.9 ------------------ total 16.4 04:19Z Cart 03, plate 2199 (chunk115). Guide stars on goToField. Plate was declared done with four exposures. 06:02Z Cart 04, plate 2169 (chunk112). Guide stars on goToField. Plate was declared done with three exposures. 07:19Z Cart 05, plate 2248 (segue121). We had to use find an Fk5 star to find the field. During the third exposure, poor seeing (~3.5") became a problem. Wind was out of the east. 08:54Z We closed because of increasing humidity and a very strong storm just north-east of the site. endNight finished and was happy.
