The waxing gibbous Moon will occult (cover) the magnitude +3.8 star Omicron Sagittarii for observers in Canada and northern USA during the night of 2018 JUL 25-26.

The current series of 19 monthly Omicron Sagittarii occultations extends from 2018 JUN 01 to 2019 OCT 05. However the large majority are not visible at nighttime from any particular location. The next series will commence on 2028 OCT 23.

The upcoming immersion will occur on the lunar dark limb and emersion on the bright limb. Observers on the only graze path will witness the star winking on and off as lunar hills and valleys pass by. That includes the vicinities of Salt Lake City, New York City and Boston. Those north of the path will see a full occultation.

I’ve created a graze map for North America, a set of Besselian elements for computer input, and preview graphics with data for Chicago. They can be seen by visiting my Occultations webpage at www.CurtRenz.com/occultations.html

Photos and descriptions of the occultation 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.
