(7225) HUNTRESS
     D. Pray, Carbuncle Hill Observatory, Greene, RI, U.S.A.; P. Pravec, P.
Kusnirak, and K. Hornoch, Ondrejov Observatory; M. Husarik, M. Pikler, and
G. Cervak, Skalnate Pleso Observatory; S. Gajdos, Modra Observatory; and F.
Colas and J. Lecacheux, IMCCE and Pic du Midi Observatory, report that
photometric observations obtained during 2007 Dec. 7 to 2008 Jan. 17 reveal
that minor planet (7225) is a binary system with an orbital period of 14.67
+/- 0.01 hr.  The primary shows a period of 2.4400 +/- 0.0001 hr, and it has
a lightcurve amplitude of 0.11 mag, suggesting a nearly spheroidal shape.
Mutual eclipse/occultation events indicate a secondary-to-primary
mean-diameter ratio of 0.21 +/- 0.02.
