THE CHRISTMAS STAR IS A DVD PRESENTATION.
In this DVD scholars discuss if the Star of Bethlehem was a real astronomical event?
COMETS IS AN INDOOR ACTIVITY IN WHICH INCLUDES MAKING A COMET AND A SLIDE SHOW.
What is a comet? You make a comet. Where do comets come from? Why do comets have tails? What are periodic comets & sun grazers?
STAR PARTY (WEATHER PERMITTING i.e. must be able to see the stars)
When coming to a Star Party you should dress warm. It does get cold at night, even in the summer.
Bring a red flashlight. If you don’t have a red flashlight, the observatory can cover the lens of a flashlight with a red covering.
This is to protect everyone’s night vision. The observatory also has hand & toe warmers, a covered building, and hot drinks will be
available. The observatory does not charge for these Star Parties but does accept donations.
The party starts at Astronomical Twilight, which is when the Sun is approximately 18 degrees below the horizon (about one hour after
sunset). Beginning with; how to and finding the North Star. We proceed with a tour of the night sky pointing out constellations,
planets, asterisms, and where some astronomical objects are located. After the tour there will be telescopes set up for viewing of
If you have a telescope and would like to participate come early to set up. Astronomers are more than willing to help you set up and
help you find astronomical objects in the sky.
Handouts with pictures of some of the astronomical objects that can be seen the night of the Star Party are available (free) as a
memento of the Star Party. This handout has a place where the astronomer fills out telescope information, and their name. You can
then show your friends what you saw at the star party.
This event can also be done at your location.
Here some student astronomers watch with Joe in the Observatory control room as a comet crashes into the
sun. Joe has student classes at the observatory on a regular basis. Check the Cottontail Observatory

Glacier National Park and is northern counterpart in Canada, Waterton, are establishing astronomy programs for
the visiting public. It's very exciting and gratifying to show people from all over the world things most of them have never seen.
With the wondrous natural beauty of Glacier and Waterton as a primer, it's pretty easy for us to "wow" them. Here's Joe and Gwen
with good friend and fellow amateur astronomer Jerry Armstrong from the Tacoma Astronomical Society setting up in Waterton.
joining them were a few members of the Royal Astronomical Society of Canada. Several of us will return to Waterton this August 15
(Update: 2015 date is July 17-18) to make this an annual event.
Here are some pictures taken by Joe Witherspoon from the Cottontail Observatory on the 22nd of June 2015
