Asteroid 61330 2000 OT58 is a main belt asteroid with an estimated diameter of 10 km. It was discovered on 29 July, 2000 by LONEOS at Anderson Mesa. The semi-major axis is 2.20 AU, the eccentricity is 0.202 and the inclination is 3.35 degrees.
This asteroid was observed on 2 nights during May 2011 when it was in the field of another asteroid I was observing. Analysis of the data was very frustrating as the asteroid was quite faint. This meant that the lightcurve was dominated by noise and no reliable period could be determined.
