La Cañada Observatory, is an initiative by Juan Lacruz, the observatory started astrometric operations in the summer of 2002, it is registered as station J87 in the Minor Planet Center of the International Astronomical Union.

The Observatory also participates in the studies on minor bodies promoted by the Group on Meteorites, Minor Bodies, and Planetary Sciences of the Institute of Space Sciences (CSIC-IEEC).

2010 HQ23, a new discovery on 2010 April 23th




I've found this as an unidentified object at magnitud 20V on the night of 23-Apr-2010, then acquired followup observations one week after on 01-May-2010, the Minor Planet Center designated the object as 2010 HQ23 although no orbit was published neither I got the new designation (it indicates whether you're the discoverer or not). Last night, 07-May-2010 in between the clouds I obtained further astrometry and this morning the MPC issued the orbit :

2010 HQ23

Epoch 2010 Apr. 14.0 TT = JDT 2455300.5 MPC

a = 2.3290709
q = 1.7209932
e = 0.2610816
i = 6.89705

From 9 observations 2010 Apr. 23-May 7.

The observations collected so far belong just to my observatory, the residuals look quite good, the worst being +0.7 arc seconds in declination the night of the discovery.

It's a pleasure to verify that even with those big telescopes surveying the sky so frequently and deep, we amateurs still have the chance to discover asteroids eventually.

Look at the orbit at JPL orbits

This asteroid in the inner main belt approaches the orbit of Mars.
