Ondrejov Asteroid Photometry Project

Dataset with Binary Asteroid Parameters that has been originally published in Icarus 190 (2007) 250-259 (get reprint) and that is updated reguarly is available. Page on the Photometric Survey of Asynchronous Binary Asteroids project. Page with a summary of prepublished data is updated regularly. Other routine observations are mentioned here. This composite lightcurve of binary NEA 65803 Didymos (reprinted from Pravec et al., 2005, Photometric Survey of Binary Near-Earth Asteroids; see the note below) is an example of data resulted from the Photometric Survey for Asynchronous Binary Asteroids run from the Ondrejov Observatory and other collaborating stations (see the link above). Main tasks of the Ondrejov Asteroid Photometry Project are: Study of asynchronous binary asteroids among NEAs, Mars crossers, and inner MBAs. Study of small asteroids with interesting rotations, like tumblers. People of the Ondrejov Asteroid group: Petr Pravec (PI, ppravec@asu.cas.cz) Petr Scheirich Peter Kusnirak (principal observer, peter@asu.cas.cz) Kamil Hornoch Adrian Galád Mirek Velen Collaborators: Marek Wolf Lenka Kotkova-Sarounova
