Amor NEO 2008 EM8

2008 EM8, was detected as an unidentified object at La Cañada Observatory on 2008 Mar 08, because its special movement I reported it as NEOCP (Near Erth Object Confirmation Page) candidate to the MPC(Minor Planet Center) but it didn't make through the NEO confirmation page.

I contacted Rafael Ferrando at observatory 941 Pla d'Arguines, he confirmed its existence and sent the observations to the MPC.

Only objects with a NEO rating above 50% get to the confirmation page and this one, using the data from J87 La Cañada and 941 Pla d'Arguines observations, "only" scored 46%.

Two days later, on 2008 Mar 10 the MPC issued a discovery circular MPEC 2008-E82 crediting the discovery to the observatory G96 Mount Lemmon 1.5m reflector with a single night two days before.

This object is an AMOR NEO with perihelion q = 1.28.

Finally I got the designation back from the MPC to confirm that my unidentified observations belong to this NEO on 2008 March the 12th.


  1. Por los pelos, Juan, pero buen trabajo. Por cierto, he estado con Rafael Ferrando en Castellón, aunque no le comenté nada de esto puesto que no lo sabía aun. A ver si no se vuelven a adelantar los del monte limoncete, un saludo.

  2. La noche siguiente no lo pude seguir porque hizo mal tiempo, de otra manera, con dos noches seguidas, es posible que el mpc me lo hubiera acreditado. Otra vez será :-).
