View Full Version : Moon Occults Gamma Librae - Evening October 4

2016-Oct-01, 05:07 PM
The 14% illuminated waxing crescent Moon will occult (cover) the magnitude +3.9 star Gamma Librae for observers in North America during the late afternoon and early evening of Tuesday 2016 OCT 04.

Immersion will occur on the lunar dark limb and emersion on the bright limb. Observers on a graze path will witness the star winking on and off as hills and valleys pass by. Observers between the graze paths will see a full occultation.

Iíve created a North American graze map, preview graphics with data for Chicago, and Besselian elements for input to a computer program. They can be seen by visiting my Occultations webpage at www.CurtRenz.com/occultations.html

Photos and descriptions of the event would be welcome additions to this thread. If you would like specific occultation or graze predictions for your location, please reply to this post with your longitude, latitude, elevation and time zone.
