La Caņada observatory, NEOCP Observations

Home page   

(Last updated 2010 July 21)

This is a compilation of observations of objects posted by the Minor Planet Center on the NEO Confirmation Page (NEOCP).
Most of this confirming observations, unless the object turns out to be non interesting, are issued in an electronic circular (MPEC).
In some of these objects it was also detected cometary activity, in such cases there's an additional circular of the International Astronomical Union (IAUC).

2010 OA RO4B8DB 17.07.2010 2010-O08 On 2010 July 18.03 working in remote from Madrid, I've confirmed this recently discovered object which was posted on the NEOCP with the observatory designation RO4B8DB, very low in the sky, at only 15 degrees of elevation an moving fast, at nearly 4 arc seconds per minute, this wouldn't seem an easy target if not for the relative brightness about 17 V, some sixty images of 20 seconds each arranged in three stacks of twenty resulted enough to perform astrometry with good signal to noise ratios and low residuals about 0.5 arc seconds.
2010 NG 05.07.2010 2010-N15 An object posted on MPCs NEOCP was confirmed on a stack of images taken remotely from Madrid on 2010 July 04. Moving at 6 arc seconds per minute at magnitud 19V didn't seem an easy object however the night was clear enough to allow an early detection with small residuals. Because the resulting plate scale of the telescope + CCD system is about 1.2 arc seconds per pixel, the exposure used was 10 seconds per frame, short enough to prevent the asteroid drift.
2010 LN14 TAL601 07.06.2010 2010-L30 The night of the Sunday 06 june 2010, working remotely from Madrid, I contributed to the confirmation of two objects posted on the MPC's NEO confirmation page (NEOCP), one of them (TAL 601) was moving quite fast, at about 4"/sec, allowing only short exposures max 20 seconds :
TAL 601 = 2010 LN14 Apollo object
2010 LJ14 SW40jD 07.06.2010 2010-L27 This is an amor object, it grazes the Earth's orbit at a periheion of 1.1 AU, see the orbit diagram at JPL orbits

Brinkworth and M. Burleigh (La Palma). The orbit shows a perihelion at about 1.1 A.U. on July 10, 2003. The period is about 4.8 years, the third shortes on record for an existing comet. The comet approached Jupiter in Jan. 2001, at about 0.55 A.U., before which the perihelion distance was somewhat larger. This is LINEARs 110th discovery. (VdS Fachgruppe Kometen)

This is the first time a comet was posted at the JPL risk page.
