These are based on half-arcsecond Monte Carlo noise?: [no me neither but http://en.wikipedia.org/wiki/Monte_Carlo_method gives an idea ]
The corresponding calculated impact times and locations are listed at

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 entry.

The OP's pic looks rather like the Asteroids game. Co-incidence..
Except it's not my picture, it a developing plot of impact points.If you had
, you would have realised that the importance of lil old AA2014 was the fact that not one of the "agencies" caught it until 20 hours before Earth impact. Because it arrived over a period of "celebration" and the "agencies" were, initially, non functional. Pixelpeep said:

"It was New Year's Eve, but that didn't stop observer Richard Kowalski from scanning the sky for near-Earth objects (NEOs).
He hadn't been using the 60-inch telescope on Arizona's Mount Lemmon for long when he noticed a 19th-magnitude blip skimming through northern Orion in a seven-image series begun at 5:16 p.m. (1:16 Universal Time on January 1st). After confirming that it was a new find, Kowalski dutifully submitted positions and times to the IAU's Minor Planet Center. Then he went back to the night's observing run."
