Near-Earth Asteroids

David Asher again visited the Bisei Spaceguard Center in Japan, and took part in the further development of software for the automatic detection and position measurement of near-Earth objects (NEOs) and other asteroids and comets. The Bisei system surveys the sky to add to the world database on objects with the potential to impact the Earth. David Asher was also part of an international collaboration led by Andrea Boattini (Osservatorio Astronomico di Roma, Italy) to use large-aperture telescopes (2-4m aperture) at La Silla, Chile, for making observations of NEOs that would be impossible using smaller instruments.
