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.

[2/12] Evolution of a solar flare associated with active region AR13664. The flare was a class X3.98 event (very large!) Images captured in H
α light at 06:33, 06:56 and 07:00 UT follow the evolution of the flare from shortly after it erupted. 10 May 2024. John Hughes.

[5/12] A montage of images by Martin Cook (MPC) and Steve McElvanney (SM) shows the motion of sunspots L-R across the solar disk (caused by the rotation of the Sun). Sunspots identified using
Spaceweather.com. 14-19 April 2024.
[6/12] A faint auroral display was visible from southern England on the evening of 19 April 2024. The glow could be captured in photographs, although the colouration was subtle. LHS: Adam Honeybell, Needham Lake. RHS: Paul Whiting FRAS, Felixstowe Ferry Golf Course.
