Comet C/2010 G3 (WISE)

A comet was discovered in images from the the Wide-field Infrared Survey Explorer (WISE) satellite on April 14.14. The 19th magnitude object showed a coma and tail, and was the brightest seen so far in the 22 micron band. The comet was at perihelion at 4.9 AU in April.  Brian Marsden notes on MPEC 2010-M42 [2010 June 22] that The "original" and "future" barycentric values of 1/a are +0.000613 and +0.000922 (+/- 0.000058) AU^-1, respectively.

The moderate "original" value suggests that this comet has made a previous visit to the inner solar system.
