Moon occults Pleiades   Message List

Copied from a thread on http://www.cloudynights.com

An occultation of the Pleiades star cluster (M45) by the Moon will
occur during the evening of 2006 APR 01 (Saturday) and will be a
nighttime event across the eastern half of North America and
northwestern South America.

Since the crescent Moon's apparent disk will be only 17%
illuminated, this will make for a better photographic event than its
immediate predecessors in this series. Additionally, the fact that
the Moon will be waxing will enhance the ability to observe
immersions (disappearances) of individual stars. This should be the
finest opportunity for observers in eastern North America during the
entire 2005-10 Pleiades occultation series.

I've created three graphics that are related to the event. They can
be seen by going to http://www.curtrenz.com/astronomical.html

The first graphic is a pictorial preview of the occultation as it
will be seen from Chicago's Adler Planetarium when the Pleiades
brightest star, Alcyone at Mag 2.9, is most fully covered by the
Moon.

The second graphic is a map of the Americas depicting the graze
paths of the Pleiades 7 brightest stars. Any person located between
the northern and southern graze paths of any particular star can
witness a full occultation. Anyone directly on a graze path will be
able to observe a star winking on and off as hills and valleys of
one of the Moon's polar regions pass by.

The third graphic is a map of the region south of Chicago depicting
the northern path for the twilight graze of the Pleiades 4th
brightest star, Maia at Mag 3.9.
