Sharp increase in number of <0.5AU asteroids for current period
In the previous 24-hours, the number of <0.5AU asteroid discoveries for current period (L) has sharply increased from 284 to 1199 (increase of 915). 1 AU = ~150 million kilometers
As of yesterday, the most recent announced discovery was 2016 LJ11 (decimal equivalent = 2016, L, 284). As of 07:55 British Summer Time, this has been superseded by 2016 LY47 (decimal equivalent = 2016, L, 1199).
Within those 915 new discoveries, none have a close-approach of <10LD - which is quite unusual.
Normally (whatever 'normal' is), 0.7% of the running total <0.5AU discoveries are in the <10LD range, with 0.1% of the running total making a close-approach <1LD.
1 LD = Lunar Distance = ~384,000 kilometers
Remarks:
1) New period "M" starts as of 00:00 Thu-16-June-2016.
2) In comparison, 2015 (periods A-L inclusive) saw a total of 47,551 new <0.5AU discoveries. For the same period of 2016, so far, there have been a total of 29,742 new <0.5AU discoveries - so we're currently 'down' by 37.5% on last year's totals (so far).

There are 30 asteroids listed in this table. 8 are less than 1LD. 1 of them (2015 DY30) was below geo-stationary (22,236 miles) altitude - at a distance of +/- 5,000 miles from Earth surface. YPD refers to Year of discovery, NASA period of discovery, and the (decimal format) number of the object within the stated period. E.g. 2016:C/726 = the 726th NEO discovery of NASA Period "C" (Feb1-Feb15), from year 2016.

NEO Asteroids Close Approaches January 2016
January we will likely have a large meteorite fall/s so MeteorRats be on standby!
Updates Pending!
LunarMeteoriteHunter, Tokyo
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 currently2 .... 22 known NEO Asteroids discovered that will pass within approximately 10LD or less (LD stands for "Lunar Distance"), in the month of January 2016. I expect that 10-15 or more 10LD NEOs will be discovered before month end.
Expect some spectacular bolides, fireballs, and meteors this month and especially large ones 3-5 days before and following the passing of 13 small mountain-sized NEO asteroids and 1 comet, diameters ranging from 500m- 2.5.km, that will safely pass this month.
Be ready for some bolide, fireball, and meteor activity!
