Goodbye 2644

The M5.8 solar flare was associated with a coronal mass ejection that is heading well west and away from Earth. There is no chance that this plasma cloud will arrive at Earth.

Sunspot region 2644 is now located at the western limb and will now slowly rotate onto the far side in the coming 24 hours. M-class activity remains possible from Active Region 2644 until it has fully rotated behind the western limb.

Sunspot region 2645

Sunspot region 2645 was relatively quiet today compared to sunspot region 2644 as it only produced a couple of C-class events. It keeps its Beta-Gamma-Delta magnetic layout but did show signs of decay. It's magnetic delta structure in the trailing portion of group has weakened. It can still produce an M-class event but it needs to be quick if we want to have an earth-facing eruption! Click here to view the most recent SDO imagery of sunspot region 2645.
