Available and desirable dates
See the previous section for assigned dates.
Note: Many Friday nights are assigned to SJAA public star
parties, so they are not available for schools.
Desirability is determined by the phase of the Moon. The moon is
spectacular and well-liked, very desirable for a public event.
Such dates are:
Dates with no moon in the evening sky are more plentiful.
There are many star clusters, colorful double stars, etc.,
so the sky is very rewarding. Consider:
Too much moon (over 75% illuminated) makes it difficult to
show anything but a few bright objects, so we try to stay away from
the nearly-full moon. It's a poor show, and not fair to the students
(nor to the astronomers). But we could use them if nothing else is
available, such as a make-up date for a clouded-out evening.
May 20-22, 24-27.
Approximate starting times through the year:
The earliest practical time is probably 6:30 pm, allowing
parents to get home, eat, and get to school. That's as early
as we prefer to start. But in late spring thru early fall, the
sun sets rather late, and star parties must start late, too.
On March 10, 2013 we advanced the clocks, and start times
jumped to 8:15. By April 1, 8:30; April 14, 8:45; May 1, 9;00; May 15, 9:15;
June 1, 9:30; June 15, 9:45; July 1, 9:45; July 15, 9:30;
August 1, 9:15; August 15, 9:00; September 1, 8:45; September 15, 8:15;
October 1, 7:45; October 15, 7:30; November 1, 7:15.
DST will end on Nov.3, 2013, and the earliest start time will drop
to 6:30 and will remain there for a few months.
By February 8 the sun sets later, and start time moves up
to 6:45 pm; February 22, 7:00; March, 7:15.
And the cycle repeats.
