Observations of Asteroids in International Scientific Optical Network

4 p.; International audience; The International Scientific Optical Network (ISON) was established in 2004 to carry out regular monitoring of the population of artificial objects at high altitude orbits (mainly GEO). Now the network joins 23 observatories in 10 countries, which are located at different longitudes and latitudes of the globe (Molotov et al., 2009). Since 2006 the photometric observations of asteroids has been started in frame of ISON to increase the network scientific output. The main targets of these observations are near-Earth asteroids (NEAs) as hazardous objects pose a threat for the Earth civilization. The observations are aimed to investigate physical properties of the asteroids and astrometric positions. The network is also involved into projects on searching binary asteroids, support of asteroid radar research and investigation of the YORP effect. In last two years the project was also directed to be involved in follow-up and discovery asteroids and comets, especially NEAs in frame of the Asteroid Hazard problem. Capabilities of our network to obtain astrometry and photometric data can be used in frame of the project GAIA for doing observations of newly discovered asteroids and comets.
