OASI is a society for people interested in astronomy. We are based at Orwell Park Observatory and Newbourne Village Hall, both situated near Ipswich, Suffolk. Members enjoy a wide range of interests in astronomy and include armchair astronomers, casual observers, and dedicated amateurs with specialist skills in visual and photographic observing, constructing telescopes, public education in astronomy and the history of astronomy.

[1/10] OASI observers along with many members of the public gathered on Cliff Road, Felixstowe, hoping to observe the Moon, in total eclipse, rising above the eastern horizon, on 07 september 2025. Unfortunately, cloud prevented visibility of total phase of the eclipse, but breaks in the cloud enabled observation of the subsequent partial phase.

[5/10] OASI attended the Latitude Festival on 25-26 July to run sessions on solar observing and night-time observing. On 25 July, there were breaks in the cloud enabling some lucky festival-goers to use the telescopes to advantage. By 11.00pm, the sky was clouded out apart from quick glimpses of the brighter stars. Photos, L->R, T->B: observing the night sky while Sting's pyrotechnics illuminate the background, setting up the OASI stand, some lucky individuals observing the Sun through solar telescopes, Professors Lintot and Fong holding forth.
