We are pleased to report the discovery of a several-Jupiter mass
planetary companion to the primary star in microlensing event
OGLE-2005-BLG-071. This is the second clear detection of a planet using
the microlensing technique. Data for this event comes from the OGLE,
MicroFUN, MOA, PLANET, and RoboNet collaborations. Photometry at the
peak of the event (see below) yields an extremely clean detection of
deviation from the light curve expected from an isolated lens. Detailed
modeling of the light curve gives a tightly-constrained planet-to-star
mass ratio of q=m_p/M=0.007.

the OGLE, MicroFUN, MOA, PLANET, and RoboNet sites.
