3637 O'Meara is a main belt asteroid with an estimated diameter of about 15 km. It was discovered on October 23, 1984 by B. A. Skiff at Flagstaff. The semi-major axis is 2.54 AU, the eccentricity is 0.127 and the inclination is 14.32 degrees.
Asteroid 3637 O'Meara was observed on six nights during August and September 2008. The resulting lightcurve was extremely difficult to analyse as each observing session only covered a small portion of the period and the lightcurve appeared to be very asymmetric. The most reasonable peroid that could be derived was 13.704 hours, but this is quite uncertain. More work is required on this asteroid.
