The Sun gets active with X-class solar flares

 

September 2011 has been an active month for the Sun.

 

Having already unleashed two X-flares since Sept. 22nd, sunspot Active Region (AR) 1302 appears to be ready for more action, and is so large that 10 Earths could fit side by side across it.

Mike Cripps 1959-2011

 

It is with great sadness that we acknowledge the sudden and untimely death of Mike Cripps. He was an inspirational teacher and a passionate amateur astronomer. He worked with us on Sun|trek and contributed many of the educational resources.

The Sun shines on Glastonbury

The Sun shines on Glastonbury

 

'Wow, that's amazing!' - Sunshine at Glastonbury, yes, but they were actually talking about seeing the Sun through an H-alpha telescope.

 

Sometimes as astronomers we forget the thrill of looking through a telescope for the first time, but this is what happened at the Festival this year. We also had the night-time telescopes out to look at the beautiful full Moon. A double whammy for some was to see both to see the Sun and the Moon within a few hours of each other.

Safe observations of the Sun with small telescopes

Safe observations of the Sun with small telescopes

 

A new section has been added to the Sun|trek site to provide a guide to amateur astronomers who want to observe the Sun and also to teachers who would like to carry out some solar astronomy at school.

The first question one might ask is Why observe the Sun? For a start, the Sun is our local star and it is always changing. It can be observed during that daytime, which is a distinct advantage for school projects and clubs. The Sun can be observed at any time during the year, providing of course that it is not cloudy.
