The 71% illuminated waxing gibbous Moon will occult magnitude +2.9 Pi Scorpii for North Americans during the evening of 2009 JUL 30. Immersion will occur on the lunar dark limb and emersion on the bright limb. The southern graze path will pass through states in the southeastern USA. The northern graze path will be in outer space above the North Pole. Observers on the graze path will have an opportunity to watch a star winking on and off as lunar hills and valleys pass by. Those north of the path will witness both ends of an occultation.

I’ve created a graze map that can be seen by clicking: www.curtrenz.com/astronomical

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

I joined three years ago and have finally decided to start learning. Your map for July 30, 2009 shows the area from Dallas and upward to the state of Washington. Will people in the Chicago area be able to see anything if the sky is clear? Thank you, Rainbowangel.

Welcome to becoming an active member of the discussion group, rainbowangel.

The map shows the southern limit of the occultation, so we’ll see it from Chicagoland if the sky is clear. For observers at the Adler Planetarium, I predict immersion will occur at 20:40:42 CDT and emersion at 21:44:32 CDT.

Thanks for the quick response. Yesterday, it was too cloudy to see anything. Tomorrow at 8:40 p.m. I will be going to the deck to try and locate the Moon Occulting at Pi Scorpii. appreciate your input - the maps you outline are great too.
