There are over 200 amateur astronomical societies in the UK. From giving a child their first look through a telescope to running talks and hands-on events, societies have a huge impact on the science communication landscape. Many societies are embedded in communities otherwise under-served by science engagement opportunities.
This website shares outreach resources suitable for use by astronomical societies. AstroBoost also runs projects to provide societies with free outreach resources and training.
I also manage a UK-wide email discussion list for non-formal astronomy educators at AstroMailbox . Sign up to share ideas and resources with a wide community of outreachers from astronomy societies, academia, planetariums, science centres, and more; and to hear the latest news and opportunities.
