A Sun Spot

25 Aug 2010

At http://www.cieletespace.fr/node/5752 the website of Ciel et l'Espace, a French astronomy magazine, has published a picture of a sun spote (below)

It is the most detailed ever taken in visible light - and the website intends to publish further images. They have an origin in the US, at the Big Bear Solar Observatory, a unique location on a lake (see http://wattsupwiththat.com )
