September 2015 NEO Asteroids Close Approaches
c2015 Dirk Ross- Tokyo, Japan
September ALERT- Increased Meteor Activity! 
Expect some spectacular bolides,  fireballs, and meteors this month and especially large ones 3-5 days before and following the passing of  5 or 6 small mountain-sized NEO asteroids and 1 comet, diameters ranging from 500m- 2.0km,  that will safely pass this month.

Please report your meteor sightings to this website for posting- Remember IF you are looking for a report and no one reports then everyone lacks information; thank you.
http://lunarmeteoritehunters.blogspot.jp/2000/11/meteor-fireball-report-form.html

There are currently 1  15 18 known NEO Asteroids discovered that will pass within approximately 10LD or less (LD stands for "Lunar Distance"), in the month of September 2015.
I expect that 10 or more 10LD NEOs will be discovered before month end.
Be ready for some bolide, fireball, and meteor activity!
Cameras Ready!
If you get video or photo of a meteor please email to - LunarMeteoriteHunter@gmail.com
