At the Hampshire Astronomical Group observatory the telescopes have been used to confirm discoveries of supernovae (exploding stars in distant galaxies) by other astronomers who discovered these objects.
Two of the telescopes on site have been given official recognition and codes by the International Minor Planet Centre in USA for the positional accuracy of observations of Asteroids taken at the observatory. This means the observations are of high standard and will be accepted by the professional astronomers world-wide.
Astrometric (positional) measurements of Near Earth Objects (NEOs) have been made at the observatory which has helped professional astronomers to precisely resolve the orbits of these asteroids. These observations help to identify objects that could threaten Earth in future years.
We are participating in observations of Comets and their Nuclei and observing for potential break-up of these objects as they are subject to gravitational stresses as they orbit the sun.
The group undertake observations of fireballs and other meteoric phenomena and report our findings to National databases.
Our members participate in expeditions around the world to observe Total Eclipses of the Sun.
