Third comet discovered at J75 in the course of LSSS ;-)

This comet was first discovered as an asteroid, but later images from the WISE project found it to be a periodic comet!

    * Identification!: An apparently asteroidal object, discovered on Nov. 19, 2009, in the course of the La Sagra Sky Survey (LSSS) has been found to show cometary appearance in images taken in the course of the WISE mission. Upon request of the MPC M. T. Read and J. V. Scotti (Spacewatch) and W. H. Ryan and E. V. Ryan (McDonald Observatory) were able to confirm this result. Additionally, the comet was identified with a two-night detection by LINEAR of May 8, and 10, 2005, then named 2005 JR71. The orbit for comet P/2009 WJ50 =2005 JR71 (La Sagra) shows perihelion on Mar. 12, 2010, at about 1.79 AU. The period is about 5.3 years. This is the 6th amateur comet discovery in 2009, and the 3rd for the La Sagra Survey. (IAUC 9117, MPEC 2010-D01, -D02)
