  The microlensing event OGLE-2002-BLG-055 has a single, but very reliable data
point, deviating upward from a single source microlensing light curve by 0.6
mag. The simplest interpretation calls for a binary lens with a strong parallax
effect and the mass ratio in the range 0.01 - 0.001, putting the companion in
the Jupiter mass range. Given only a single deviant point it is impossible to
fit a unique model. We propose a modification of OGLE observing strategy:
instant verification of a reality of future deviant points, followed by a
frequent time sampling, to make a unique model fit possible.
