About

Established in 2008, Astrotalkuk.org is a not for profit,  amateur astronomy audio (sometimes video too) podcast based in the UK.  See or download a pdf summary of all episodes. The summary is updated .. irregularly.

For my day job I work in the Information Security area and this blog now occasionally includes some posts associated with that, especially with a focus on Cloud Computing.

The host
Gurbir Singh is an amateur astronomer and author, well  just about, one book (Yuri Gagarin in London and Manchester). He has been involved in amateur Astronomy for over 30 years. Based just outside Manchester, he works in the IT industry.
