My Facebook feeds from astronomy groups and pages have exploded with the news: a tiny and recently discovered asteroid 2014 AA (approx 4 meters in
diameter) has exploded in the Earth's atmosphere, somewhere off the coast of West Africa. It would have produced an air-burst comparable to a small
nuclear bomb, similar to the 2008 TC3
asteroid that exploded over Africa.
It is virtually certain that 2014 AA hit the Earth's atmosphere on 2014 Jan. 2.2 +/- 0.4, as demonstrated by independent calculations by Bill
Gray, the MPC and Steve Chesley (JPL). According to Chesley, the impact locations are widely distributed, most likely falling on an arc extending
from Central America to East Africa, with a best-fit location just off the coast of West Africa on Jan. 2.10. 2014 AA was unlikely to have survived
atmospheric entry intact, as it was comparable in size to 2008 TC3, the only other example of an impacting object observed prior to atmospheric
Below you can see the two maps of the possible impact region made by Bill Gray.

I will post more updates soon, as they are coming.
P.S. Here are impact simulation results, using the same impact velocity and angle as 2008 TC3:
It's an air-burst, but some fragments may make their way to the surface (in this case, most probably the Atlantic ocean). Air-burst energy = 0.5
