We’ve had a major spurt of solar activity lately, and overnight on 7th March 2012 we had two X-class flares (the largest classification!) in close succession, an X5 followed shortly after by an X1. Check out this still of the arcade just after the flares. For more info, head over to The Sun Today for a feature video!
Last week the RHESSI satellite celebrated 10 years since it’s launch in February 2002. A NASA small explorer mission, RHESSI has been observing the energetics of solar flares, and has spawned over 1000 scientific papers featuring its data. To mark this occasion, the latest entry in the regular RHESSI science nugget series was devoted to RHESSI’s best discoveries. Read the nugget here.
After gaining a few spare moments, I made an effort to make a slight redesign of this website. Here’s the result. The jury is still out, but I will give it a try for a while to see if I like it!
The Sun has unleashed the largest flare of the new solar cycle so far, an X7-class event observed by the Solar Dynamics observatory and many other instruments. The flare started at 07:48 UT on 9th August 2011, peaking just after 08:00 UT.
