CESRA
The Community of European Solar Radio Astronomers (CESRA) is a non-profit informal organization of European scientists whose aims are to promote studies of solar radio physics and related topics.

Established in 1970, its membership includes scientists from 28 European research institutes.

Conferences 
CESRA organizes triennial workshops on investigations of the solar atmosphere using radio and other observations. Although special emphasis is given to radio diagnostics, the workshop topics are of interest to a large community of solar physicists. The format of the workshops usually combine plenary sessions and working group sessions, with invited review talks, oral contributions, and posters. The workshops attract not only European scientists, but also scientists from the USA, China, Japan, Australia, and Brazil. 
CESRA has also cosponsored international solar physics conferences organized by the European Physical Society and in one occasion has organized a session within the European Geophysical Society's General Assembly.

CESRA web page hosts “Solar radio science highlights”.  These are short communications written by CESRA members that publicize fresh research (normally based on a refereed paper published within three months) to keep CESRA community informed and up-to-date. They are written in a language accessible to  non-experts, using a “news-and-views” style.
