Central Bureau for Astronomical Telegrams, No.270, 2 November 2005, for (9260) Edwardolson A photometric observations between 6 and 30 October 2005, show that 9260 Edwardolson is a binary system with an orbital period of 17.785±0.003 hours. The primary rotates with a period of 3.0852±0.0001 hours, and its lightcurve has a brightness variation of 0.11 magnitude, which is indicative of a nearly spheroidal shape. Mutual eclipse/occultation events, that are between 0.08 and 0.15 magnitude deep, indicate a secondary-to-primary mean-diameter ratio of 0.27±0.03. Reported by M. Jakubik and M. Husarik, Skalnate Pleso Observatory; J. Vilagi, S. Gajdos, and A. Galad, Modra Observatory; P. Pravec and P. Kusnirak, Ondrejov Observatory; W. Cooney, J. Gross and D.
