M4.4 solar flare

Not a prank! We just had the first M-class solar flare since November last year!

Sunspot region 2645

Sunspot region 2645 has gone Beta-Gamma-Delta! Beta-Gamma-What? Yes, Beta-Gamma-Delta. We give this classification to the most complex magnetic figuration a sunspot region can have: umbrae of opposite polarity in a single penumbra. A sunspot group with a beta-gamma magnetic configuration that contains one (or more) delta sunspots. Let's take a closer look and see if we should expect more solar flares.
