News from the Committee

The IAS season started on 1st August 2021 and memberships fall due for renewal on that date. In the last year the ongoing restrictions due to the COVID-19 pandemic have been challenging but our online talks have reached a wide audience.

The Committee has a number of plans for the year ahead and we encourage you to join in. We hope to resume in-person meetings soon as well as to explore doing more online.

Orbit is now back (for some time) with paper printing, as Sky-High will continue to be so.

We have started on-line talks. Please see more information.

This will be a general presentation of Earth's constant celestial companion, the Moon. It's formation, physical attributes, movements, affects on the Earth and how to observe it.

Although professionally he has worked in the biotechnology and data analytical sectors, his passion is in astronomy and in particular Lunar astronomy. He has been an active observer of the Moon for over 40 years and has presented many talks on the subject in that time. He established and runs the website The Moon which is an outreach project, acting as a source of information and teaching aids on all things Lunar to individuals young and old and to various groups and schools.
