2010 HQ23 has been linked to previous observations on April the 8th by G96 Mount Lemmon and D29 Purple Mountain Obsrvatory, XuYi Station, this extends to 30 days the observed arc and doesn't change the designation neither the discovery credit of the asteroid.
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

2010 HQ23
Epoch 2010 Apr. 14.0 TT = JDT 2455300.5 MPC
a = 2.3290709
q = 1.7209932
e = 0.2610816
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.

M13 2010 Apr 10
El cúmulo globular M13 en la constelación de Hércules.
Es un grupo de unas 100.000 estrellas que orbita entorno a nuestra galaxia.
Su época de formación es similar a la de la galaxia, cuando se individualizaron decenas de cúmulos globulares.
Estos cúmulos están constituidos por estrellas de la primera generación que han envejecido y virado hacia un color rojizo al disminuir su temperatura.
También se han observado cúmulos globulares en otras galaxias.
La imagen que se muestra es una exposición de 30 segundos a través de un teleobjetivo de 200mm de focal trabajando a F2.8, el aspecto del cúmulo en la imagen es comparable al que se observaría por un pequeño telescopio con pocos aumentos.
The globular cluster M13 in Hercules.
A group around 100.000 stars orbiting our galaxy.
Its formation epoch is similar to that of the galaxy, when dozens of such clusters were formed.
The stars, of the first generation, evolved towards lower temperatures and redder colours.
Globular clusters have been found to orbit other galaxies.
The image below, a 30 seconds exposure through a 200mm focal teleobjective working at F2.8, shows M13 resembling what you'd see with a little telescope working at low magnification.

P/2010 A2 (LINEAR) The 5th Main Belt "Comet"
This makes number five of "comets" found in the Main Belt (this one in the inner belt) in typical asteroidal, non-cometary orbits.
Note that it seems to be of the Hirayama's collisional Flora family.
Note that it seems to be of the Hirayama's collisional Flora family.
The images show quite a straight tail with a separate fragment probably of a collisional origin as well.
Other two, out of the five known, seem to be of another Hirayama family, Themis .
