Nuevo Troyano (Griego) de Júpiter
En observaciones desde La Cañada el sábado 17/10/2009 detecté un objeto no identificado en magnitud 19.6 V, envié la astrometría al Minor Planet Center con la designación de observatorio LC00211. Hoy 26 octubre 2009 he recibido la designación provisional del MPC 2009 UX15 que corresponde a un objeto de tipo Troyano de Júpiter, este es el segundo Troyano descubierto desde La Cañada, el primero 2007 RK35 tiene el número 171433 y su nombre es Prothous.
(Imagen de descubrimiento, suma de 10 exposiciones de 30 segundos sin corrección de seguimiento)
Los Troyanos son asteroides que ocupan las zonas de estabilidad halladas por Lagrange como solución del problema circular restringido de los tres cuerpos.
De las cinco soluciones de Lagrange, L1, L2 y L3 son de equilibrio inestable, además hay dos soluciones, L4 y L5 que son de equilibrio estable.
Un siglo después del resultado de Lagrange se encontraron asteroides orbitando entorno al punto L4 y al L5 correspondientes a Júpiter, los asteroides en el punto L4 que preceden a Júpiter en su órbita se nombran como héroes griegos de la guerra de Troya, los asteroides en el punto L5 que van detrás de Júpiter en su movimiento orbital se nombran como héroes Troyanos. (hay alguna excepción que confirma la regla).
Tanto 2009 UX15 como 2007 RK35 orbitan el punto de libración L4 por lo que pertenecen al grupo de los griegos de Júpiter.
Se ha seguido descubriendo más Troyanos entorno a otros planetas, actualmente según el MPC hay 4 Troyanos de Marte, 3608 de Jupiter y 6 de Neptuno.
También se piensa que podría haber Troyanos de planetas extrasolares.

COMET P/2009 Q1 (HILL)
On Aug. 27 R. E. Hill with the Catalina Sky Survey 0.68-m Schmidt found this diffuse comet with no clear condensation and a 12"-15" coma with a broad, diffuse tail about 20" long in p.a. 250 deg. The object was then included in the neo confirmation page (NEOCP) for other observatories to confirm and follow up.
On Aug. 29.0, I stacked twenty 2-min images to find the object very diffuse with a round coma of size 12" and a tail 20" long in p.a. 249 deg.
This (above) is a cropped non-zoomed stack composition of 29 images of 2 minutes each taken with the .40m Ritchey-Chretien F10 + CCD at La Cañada, the North is up and the East left.

Two new asteroid designations
The night of August the 22nd I was trying to recover the asteroid K01QS8G, it is interesting because from a dynamical point of view it could be taken for a comet and it was not observed since its discovery back in 2001.
The object was there, some arc minutes off the nominal position, with the predicted magnitude, speed and direction.
In the same field another, non catalogued, object was also moving. I reported the K01QS8G observations to the mpc and kept the unided object to try and get a second night on the 23th.
You wont usually get discovery rigths unless you observe the body on two different nights.
The next night I pointed the telescope to the position where it was supposed to be and found it close to the ephemerides, to my surprise another object was moving over there.
Because it was moving at a similar speed and direction, I thought it could well be present on the same images from the night before, I prepared backward ephemerides for the new object, re-stacked the images and luckily enough it was there, then I reported booth.
The mpc, very soon, assigned new designations:
LC00190=K09Q09X
LC00191=K09Q09W
These make discovery numbers 125 and 126 in the observatory's account.

NEOCP 98LA264 --> 2009 QB23, non interesting!
I was trying to confirm this object found by the OAM J75 observatory La Sagra from the NEOCP on the night of August the 2nd in a very good night with low seeing, probably due to the uncertainty in the preliminary ephemerides available on-line from the mpc the stacked images showed a slightly diffuse object. However it resulted to be purely asteroidal, the lesson learned is that a lot of care should be taken when trying to find cometary activity by stacking frames on the movement of an object with an orbit not well known yet.

Planet Saturn, an over exposed photography to bring out some satellites.
Taken from Madrid through a 20cm (8") telescope working at F10, i.e. with a focal lenght 2000 mm, the EOS40D camera was at the primary focus.
The same conditions as in the picture above, with less exposure time showing an almost edge on rings system.

Venus phase
This picture of Venus shows the planet's phase.
Because it's low, near the horizon, the light from Venus is seen through a thick layer of atmosphere. The refraction is causing the red light to bend more than the blue.
Esta imágen de Venus muestra la fase del planeta.
Como está bajo en el horizonte, su luz es vista a través de una espesa capa de atmósfera. La refracción causa que la luz roja se curve más que la azul.

Comet C/2009 F1 Larson
This new comet discovered by S. M. Larson, University of Arizona, on survey images taken with the Mount Lemmon 1.5m telescope showing a coma diameter 4"-6" was posted on the minor planet center neo confirmation page as 9FAF233 for other observatories to confirm.
On a stack of 18 CCD images 60 seconds each in fairly good seeing a fuzziness was barely appreciated, I didn't report it to the central bureau for astronomical telegrams (CBAT) because to me, it wasn't clear enough if it was a comet.
However, other observatories noticed the diffuse aspect and the object has been recognized as a new non periodic comet.
Below you can see the analysis of the full with at half maximum for the stars in the image, most of them have FWHM = 2.5" which is good seeing for La Cañada, the comet, in red, has a much wider spread function.
Read a doc on how to detect low activity comets looking at the statistics of the FWHM.

Even though the telescope is awaiting repair, (some gears broken), the observatory continues discovering main belt asteroids, this is the case of this new designation for a main belt body first observed on 2008 Oct 25 from La Canada, independent observations by surveys G96 on 2008 Nov 3 and 703 on 2008 Nov 18 have been found to be of the same object, which makes number 115 of the designations attributed to the J87 observatory by the MPC.
The Minor Planet Center sent this designation today, 2009 Jan 10, two months and half after the discovery observations and two months since confirmations.
The absolute magnitud parameter H 15.9 suggest a size around 1.8 km assuming a typical albedo.
Incluso con el telescopio esperado reparacion, (algunos engranajes rotos), el observatorio continua descubriendo asteroides del cinturon principal, este es el caso de esta nueva designacion para un cuerpo del cinturon principal observado por primera vez el 25 oct 2008 desde La Canada, observaciones independientess por las surveys G96 el 3 de noviembre 2008 y 703 el 18 nov 2008 son del mismo objeto, que hace el numero 115 de los descubiertos desde el observatorio J87.
El Minor Planet Center envio hoy 10 enero 2009 esta designacion, unos dos meses y medio despues de las observaciones de descubrimiento y dos meses despues de ser confirmado.
El parametro de magnitud absoluta H 15.9 indica un tamano de 1.8 km suponiendo un albedo tipico.

Even though the telescope is awaiting repair, (some gears broken), the observatory continues discovering main belt asteroids, this is the case of this new designation for a main belt body first observed on 2008 Oct 25 from La Canada, independent observations by surveys G96 on 2008 Nov 3 and 703 on 2008 Nov 18 have been found to be of the same object, which makes number 115 of the designations attributed to the J87 observatory by the MPC.
The Minor Planet Center sent this designation today, 2009 Jan 10, two months and half after the discovery observations and two months since confirmations.
The absolute magnitud parameter H 15.9 suggest a size around 1.8 km assuming a typical albedo.
