- Solar flares over 6 times hotter than previously thought Tue, 9 Sep 25, 3:04amThe research, published today in Astrophysical Journal Letters, looked at evidence of how flares heat solar plasma to greater than 10 million degrees.
- Aurora watch: Sun unleashes biggest flare of this cycle — X9 Fri, 4 Oct 24, 4:10amBy Jo Nova Two X-class flares in two days, X7.1 and now X9 I put in an order for an x class flare while I’m away from city lights. I was delighted when a big X7.1 was launched on cue a couple of days ago. It was the...
- Auroras anyone? The big sunspot cluster returns and it is grumpy Thu, 30 May 24, 7:17amBy Jo Nova The big sunspot cluster that created the auroras a few weeks ago is very likely just over the horizon on the sun, and it appears to have spat out a doozy of an X2.9 flare to announce its return. While we can’t...
- Ominous space-weather: A mild Solar CME caused a bigger geomagnetic storm on Earth than anyone expected Fri, 14 May 21, 7:57pmThis week a mild Coronal Mass Ejection off the sun blasted past Earth. It was only a mild CME with solar winds at 500km per second, which is a medium kind of speed. The experts were all predicting a G1 class Geomagnetic storm,...
- Extreme solar storms hit Earth in 774 and 993AD — What would happen if one hit now? Thu, 29 Oct 15, 4:03amAugust 31, 201. This coronal mass ejection just missed Earth, according to NASA There were two mysterious sudden spikes in carbon 14 in tree rings around a thousand years ago. Now some researchers at Lund University say they’ve...
- Purdue Uni Developing Early Warning System For Solar Storms By Measuring Radiation Decay Sat, 25 Aug 12, 6:40amA team of scientists from Purdue University say they may have discovered a new method to predict solar flares more than a day before they occur. This would not only provide advance warning to help protect satellites and power...
