NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)2004 observations indicated a possible binary. The 2008 data show no obvious mutual events but a secondary period similar to the orbital period found from 2004 data shows hints of "bowing", which could be attributed to the rotation of a satellite that is tidally locked to its orbit. |
