Further observations by Naves and Montse Campas on Nov 12.08 clearly resolve two fragments with magnitudes of R=18.0 and 18.4 in a 10 arcsecond square aperture, separated by 17 arcseconds. Observations by Juan Antonio Henriquez (MPC J51, La Palma, Spain) on Nov 12.2 confirm the presence of two nuclei and give a separation of 16.5 arcseconds. Ephemeris: Date TT R. A. (2000) Decl.
