Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)Period in MPB 32, 90-92, was 79.18. Measured images using Comp Star Selector in MPO Canopus and found the new, much longer solution.
The tumbling damping time for this period is > 4.5 Gyr (see Pravec et al., 2005). No obvious signs of tumbling were found but since the data set did not fully cover the curve at least once and start into a second cycle, the lack of evidence is not proof one way or the other. This is rated PAR = 0. |
