Observing Plan and Goals for the Night¶
- Afternoon calibrations
- Standards
standards 00:22
UT Date = '2014/12/06 00:22' Local time = 21:22
E8-A ra 20:07:22 dec -44:37:01 secz 1.7

- Two TOO for David Gerdes
So the first exposures could be taken as soon as twilight ends, and the last ones could be
taken up until around 05:00 UT = 02:00 local time. During this period the fields will be below
an airmass of 1.5. Exposures should be at least an hour apart; two hours or more is better.
Both objects are currently moving at 1.2"/hour.
