Osservatorio Astronomico Amatoriale

Pietro Dora Vivarelli

2008 SQ1

La sera del 23/09/2008 sono a caccia di NEO.
L'oggetto 8S1B82E scoperto poche ore prima dalla solita Catalina ha una Mag di 18.4 con moto proprio di 0.60"/min


Il sasso ospite della costellazione di Andromeda si trovava a pochi gradi dall'asteroide 2008SE confermato da questo osservatorio nelle sere precedenti.



Il percorso dell'oggetto in 10 ore

Faccio una serie di scatti da 120" somma ed ecco che compare l'oggetto!!



Riesco ad effettuare 3 misure astrometriche, e poi corro ad inviare le misure al MPC
A poche ore di distanza l'oggetto 8S1B82E viene provvisionalmente designato con la sigla di 2008 SP1, un NEO di tipo AMOR.

Un'alta bella soddisfazione.
