Once again Earth will encounter an increase in meteor activity from passing detected and yet undetected NEOs (Near-Earth Objects) asteroids or their debris. Originally for February 2011 there were 20 known NEOs with scheduled approaches near Earth. Since January 1, 2011 there have been at least 28 new discoveries of NEOs to pass near Earth in February; this is an increase of over 100% in number for the month. There are as of today 48 NEOs discovered for February 2011 and it appears that there may be another 5-10 or more added by the end of the month. Due to the bright Moon for the remainder of the month several NEOs will go undiscovered until they pass, hit the Earth or pass silently by.
This increase in discoveries indicates to me that we will see a marked increase in meteor activity for February. I also expect that we will have a new meteorite this month.
Have your cameras ready and if possible get outside to watch. Expect to see worldwide several green meteor fireballs and bolides during, just prior to, and just after 19FEB-23FEB, and until the end of the month. If more findings come in about other newly found NEOs I will post. For the most current information see the NASA NEOs site: http://neo.jpl.nasa.gov/ca/
If anyone captures video, a photo or has a sighting please email me at: lunarmeteoritehunter@gmail.com
