Asteroid 54896 2001 OP70

54896 2001 OP70 is a main belt asteroid with an estimated diameter of 5 km. It was discovered on July 19, 2001, by LONEOS at Anderson Mesa. The semi-major axis is 2.52 AU, the eccentricity is 0.065 and the inclination is 21.86 degrees.

This asteroid was observed on 3 nights during June 2009 when it was in the field of another asteroid that I was studying. The resulting lightcurve was very noisy and a satisfactory period could not be derived. The lightcurve shown below was the best that could be obtained from the data. More observations are required to confirm or otherwise this result.
