Speaker: Andy Devey

Andy is a fifth-generation coal miner from Wakefield West Yorkshire, educated as a Mining Surveyor and as a Chartered Mining Engineer and was a colliery manager in Doncaster and Scotland in the 1990’s.

He became interested in Astronomy from an early age due to having a bedroom with no roof and later started with binocular observing until he got his first serious telescope in 2004. He became a member of MSAS in 2006 and everything went downhill from there.

A visit to his late cousin, Christina Rosana Devey an MSC Astro-physicist at Keel University in 2002 permitted his first observation of the Sun in hydrogen-alpha light and from then on, he was totally hooked.

He bought a PST in January 2005 and where the weather has permitted, he has made daily solar observations as part of the BAA solar observing programme.

He started imaging in 2009 and made the front cover of the BAA year book for 2011. He has had articles published in Astronomy Now and the BAA journal together with about 40 articles in electronic magazines. He was the first guest in the Let’s Talk Astronomy video series in 2011 shortly before he moved to southern Spain. He is proficient in outreach activities in English and Spanish and had his first article in Spanish published in November 2013 and recently has just had his first book accepted for publication in English and Spanish languages. He has posted hundreds of solar activity animations on Space Weather and achieved their front page. He also gained permission from the head of the Global Oscillation Network Group programme to use their data from 7 separate sites to make movies of solar activity and house them on his thesolarexplorer.net website that he has run since 2010.
