Observing Asteroid Occultations
are over 400,000 known asteroids orbiting the sun, with diameters
ranging from nearly 500 miles to just a few yards across. Occasionally,
one of these faint objects will pass directly in front of a star,
momentarily eclipsing it and blocking the light. Besides the dramatic
impact of seeing a star suddenly disappear and then reappear a few
seconds later, there is much that can be learned from careful
observations of such events. In this month's program we'll explore the
circumstances of asteroid occultations, how amateur astronomers can
observe them very precisely, and the important scientific results that
can be acquired through such observations.
Logo Contest Winner
now have a winner for our BAS Logo Contest. Apryl Dawn Kaylor was
presented with a certificate and one year of free membership to BAS, as
well as a copy of the book "Totality: Eclipses of the Sun", coauthored
by Ken Willcox, past president of BAS. The new logo will appear soon on
our public website.
Strycker and Steve Plank have devoted considerable time during the past
year scouting for club observing sites. We now have access to several,
from an easily accessible site at Sooner Park for casual observing, to
one of the darkest sites in our region at Hulah Lake, for more
serious observing and imaging. Arden reviewed the
schedule during the meeting and discussed plans for a possible public
star party near the end of the month. The tentative schedule for
observing events and club meetings can be viewed on our club calendar at
Oak Park Star Party
Ritchie has been in contact with Oak Park School, which would like to
have BAS provide a school star party for them, similar to the two we did
for Wayside School last spring. We weren't able to work out a date for the Oak Park Star Party this month, so
Joyce and Arden have agreed that this should be postponed until next spring,
when the weather will be better.
||December 5 - New Moon
||December 13, 14 - Geminids Meteor Shower. Considered by many to be the best meteor shower in the heavens, the Geminids
are known for producing up to 60 multicolored meteors per hour at their
peak. The peak of the shower this year should occur on the night of
December 13 and morning of the 14th, although some meteors should be
visible from December 6 - 19. Some estimates say there could be as many
as 120 meteors an hour visible from dark-sky locations. The radiant
point for this shower will be in the constellation Gemini. The Moon will
set early in the evening setting the sky up for a spectacular show.
Best viewing is usually to the east after
||December 21 - Full Moon
||December 21 - Total Lunar Eclipse. The eclipse will be visible throughout most of
eastern Asia, Australia, the Pacific Ocean, the Americas, and Europe.
The eclipse will be visible after midnight in North and South America.
Since the Moon will be almost directly overhead from these locations,
this should be an excellent chance to view a rare total lunar eclipse.

||December 21 - The Winter Solstice
occurs in the northern hemisphere at 23:38 UT. The Sun is at its lowest
point in the sky and it will be the shortest day of the year. This is
also the first day of winter.|
