The 43% illuminated waning crescent Moon will occult stars of the Pleiades (M45) cluster for North Americans during the predawn hours of 2009 AUG 14. Immersions will occur on the lunar bright limb and emersions on the dark limb. Observers located on a graze path will witness a star winking on and off as lunar hills and valleys pass by. Those between graze paths will see full occultations.
I’ve created three graphics related to the event. The first is a graze map for North America of the six brightest Pleiads. The second is a graze map for northern Illinois and southern Wisconsin of three Pleiads (2nd, 4th & 10th brightest). The third is a preview of the event as seen from Chicago’s Adler Planetarium.

Photos and descriptions of the event would be welcome additions to this thread.
