Comet 247P/LINEAR   - ( = A/2002 VP94 = P/2010 V3 (LINEAR) )


A/2002 VP94 (LINEAR) is an asteroid, of 19th magnitude, discovered by LINEAR on 2002 November 5.31. The orbit is 8.0 year , with perihelion at 1.52 AU and an eccentricity of 0.62. It is at perihelion in 2003 January, and will brighten by about a magnitude. [MPEC 2002-V70, 2002 November 15, 10-day orbit] Brian Marsden notes that it is not clear if the object is in fact a comet. This is the reason that this object has assigned with an ‘A’ and not a ‘C’.  The orbit is typical of a Jupiter family comet and it can pass within 0.4 AU of the planet.


Recovery: finally this object could be confirmed as a comet in 2010 December when observations at the Haute Province Observatory as part of the T3 project showed that this object shows a tail. This was confirmed by follow-up observations and announced on MPEC 2010-Y29 on December 27. The comet reached perihelion in early January at this return, at a distance of 1.48 AU and has a period of 7.9 years.



Recovery A/2002 VP94 - CBET 2606: An apparently asteroidal object with a comet-like orbit was discovered in 2002 by the LINEAR project , designated 2002 VP_94 (cf. MPEC 2002-V70), and observed then for well over two months. The object was again found by the LINEAR project on 2010 Nov. 15 .  R. Behrend, Geneva Observatory, and "T3 Project" (http://asteroidi.uai.it/t3.htm); J. Strajnic, Academie d'Aix- Marseille; and T. Kmieckowiak and twelve students involved with the "Le Ciel comme Labo" Project in France report that 2002 VP_94 was observed on 2010 Dec. 10.2 UT with the 0.8-m reflector at Haute-Provence Observatory, noting that a stack of 93 CCD frames representing 8400 s total exposure time shows that this object presents a faint 25"-long tail in p.a. 240 deg with a 5"-diameter coma; in the R-band, the object varies by around 0.1 mag (the period being at least 0.4 day).  Following communication from Behrend, H. Sato (Tokyo, Japan) writes that he obtained CCD images remotely using a 0.50-m f/6.8 reflector at the RAS Observatory (near Mayhill, NM, U.S.A.) on Dec. 26.1, showing a condensed coma of size 10" (red mag 16.3) and a 30" tail  toward p.a. 230 degrees.  Sato, in turn, requested that K. Kadota (Ageo, Japan, 0.25-m f/5 reflector) also take CCD images, which Kadota did on Dec. 26.6, showing a coma of diameter 0'.4 (total magnitude 16.6) and a hint of tail toward the southwest.  Also apparently in response to an alert from Behrend, L. Buzzi (Varese, Italy, 0.38-m f/6.8 reflector) obtained stacks of CCD images taken under moderate seeing on Dec. 26.7 that show a broad-but- faint tail at least 20" long in p.a. around 220 deg; a central condensation is stellar in appearance (same FWHM as nearby stars stars), and there is no visible coma around it.
