ASTRO: Jovian moon eclipse observing list for 2008 from 111W long

This is to announce a star party cheat sheet on observing 2008
eclipses of Jovian moons from the Intermountain Region (111W long),
USA.

While single and rarer double satellite transit events one of the more
popular Jovian observing pasttimes, another category of event - Jovian
satellite eclipses are also interesting.

Eighteen eclipse opportunities were extracted from the RASC 2008
Observer's Handbook that apply to the author's observing point at 111W
longitude, 41N latitude. Supplemental ephemeris data was gathered,
along with simulated images of the events and orrey graphics. The
observing list is intended for distribution as a handout at public
star parties when Jupiter first becomes visible at your observing
point. An animated gif shows the relative motions of the Earth and
Jupiter across six months of observing events. All of the simulated
views in the observing list can be seen as a Microsoft PowerPoint
slideshow.

This sky party presentation cheat sheet was originally conceived as an
observing list for school and scout parties. Kids in urban areas
typically have binoculars and light-polluted urban skies, cannot see
Jovian cloud detail, but can easily see the Galiean moons. Observing
during an eclipse emersion event would allow them to see another
active astronomical event, like a moving comet, instead of star
hopping for static objects, like globular clusters.

Beginner to advanced planetary imagers may want to consider making a
movie of a Jovian satellite emersion and immersion events. Searching
the web, there do not appear to be internet movies of such eclipse
events, except for a movie made from a 2001 Cassini flyby of Io.
