237P/LINEAR = 2002 LN13 = 2010 L2

Re-discovery/recovery via the orbiting WISE satellite of the apparently asteroidal object 2002 LN13 (discovered then by LINEAR).

IAUC 9152, 2010 June 15.

A. Mainzer, Jet Propulsion Laboratory, reports the finding of a comet on 12- and 22-micron images taken by the WISE spacecraft (discovery astrometry tabulated below), which the WISE team quickly identified to be 2002 LN_13, an apparently asteroidal object discovered by the LINEAR project (2002 discovery observation also tabulated below from MPS 57859) whose orbit was good enough to place the object within about 15" of the current position.
