"Pseudo-MPEC" for 2014 AA

EL ASTEROIDE 2014 AA SE ESTRELLÓ A UNOS 500 KM. AL ESTE DE RECIFE

Descubierto por: (G96) Mt. Lemmon Survey (N32.44287 W110.78872) US/Arizona. 
Mediciones E. C. Beshore, A. Boattini, G. J. Garradd, A. R. Gibbs, A. D. Grauer
El pequeño asteroide de entre 1 y 3 metros se adentró en la atmósfera terrestre, 
a las 2h 24m 35s.,del día 2 de enero de 2014, en las coordenadas 31º7 de longitud 
oeste y 9º3 de latitud sur, desintegrándose a unos 40 kilómetros de altura,
transformando la energía equivalente a algo menos de un Kilotón de TNT.
Tras 2008 TC3, se trata del segundo asteroide cuya órbita se ha establecido por 
la observación que impacta en la Tierra, si bien el análisis de la órbita fue 
posterior al impacto y las pocas mediciones no permiten establecer la zona de 
colisión con precisión.
