21238 Panarea           Discovered 1995 Nov. 28 by T. Kobayashi at Oizumi.
Panarea is a volcanic island placed in the south of Italy. The V-type spectrum for this object, which is located far from Vesta, suggests that it may be a new example of a basaltic achondrite asteroid having no connection to Vesta. Name suggested by R. P. Binzel, S. Foglia and G. Masi.
