NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)The asteorid appears to be tumbling and the data set was too limited to make a reasonable period detemrination. The period was originally reported at 48.2 h (MPB 33, 39-41) but arbitrary zero point adjustments were used to force a solution. |
