Nine MARVELS fields observed (one exposure each) plus evening and morning twilight tests completed. Observed for 50 minutes: Cartridge 1, plate 3078 A and B Cartridge 3, plate 3077 B Cartridge 7, plate 3074 A and B Cartridge 8, plate 3075 A and B Cartridge 9, plate 3076 A and B Details of the twilight tests (taken with the MARVELS instrument) will be in their logs/emails. ---=== OBSERVING LOG ===--- Afternoon: --------- No problems noted during afternoon checkout. No change was made to spectro focus. It should still be good for a temp of about 4 C. 23:31Z - Started ventilation 23:47Z Opened before sunset so we could have the LN2 fill done in time for a MARVELS twilight shakedown test. Night: ----- MARVELS twilight shakedown test.
