249P/LINEAR is a Jupiter-family comet with an orbital period of 4.61 years. It was discovered by LINEAR on 19 October 2006. It is only active for a brief period around perihelion.
== Observational history == The comet was at first reported as an asteroidal object with an apparent magnitude of 17.3 by LINEAR on 19 October 2006. However it was quickly found to be cometary in appearance, with a narrow tail up to 12 arcminutes long and a coma 10 arcseconds across. On 21 October the tail appeared almost disconnected from the head of the comet. A preliminary orbit suggested a short period object with an orbital period of 4.33 years. The comet was recovered on 14 January 2011 by Leonid Elenin using a remote observatory of ISON, when it had an apparent magnitude of 19–19.5.
