Abingdon Astronomical Society (AAS) is the largest amateur astronomy society in Oxfordshire serving Oxford, UK and the surrounding region. We promote public interest in astronomy in southern and western Oxfordshire through a varied programme of meetings and observing evenings for all experience levels. Our closeness to both the Rutherford Appleton Laboratory (Oxfordshire's "Space Centre") and to the University of Oxford ensures a steady stream of high-quality lectures. These, together with our more informal Beginners' Meetings and monthly observing evenings, must make us the most active amateur astronomical society in the county.
