Asteroid 14659 Gregoriana

14659 Gregoriana is a main belt asteroid with an estimated diameter of 5 km. It was discovered on January 15, 1999 by M. Tombelli and G. Forti at Montelupo. The semi-major axis is 2.64 AU, the eccentricity is 0.116 and the inclination is 11.51 degrees.

Observations of this asteroid were made on Observations were made on five nights over a six-week period during February and March 2008. The resulting lightcurve was very frustrating to analyze and no simple lightcurve was obtained. A noisy, four-peak curve with a period of 6.936 h was the most reasonable solution to the data and so is reproduced here. However, this result is very uncertain and I have a feeling that the period is actually much longer. More observations are needed at future oppositions.
