After a long period of calm, the sun awoke from its slumber and erupted with one of the most powerful solar flares of the year on Tuesday.
The most powerful solar storm of the current solar cycle is currently reverberating around the globe.
The sun has erupted with its first X-class solar flare of 2015, a not-so-subtle reminder that it can still muster the energy required to generate the most powerful class of solar explosion.
There was already a high probability that active region (AR) 2192 was going to erupt with a powerful solar flare, so it came as little surprise when two X-class flares erupted within 24 hours of eachother.
Just as the US prepares to watch the partial solar eclipse today, nearly 100 million miles away on the sun a possible solar storm is brewing. Continue reading →
A huge arc of plasma has been imaged rising from the sun's surface by a NASA solar observatory, producing a beautiful view of the sun's magnetic dynamics in action. Continue reading →
Over the past 24 hours, our planet's global magnetic field has been bombarded by two coronal mass ejections (CMEs) and now, as predicted, a "strong" geomagnetic storm is underway. Continue reading →
