New sunspot AR3762 is suddenly crackling with flares. Multiple eruptions yesterday and today quickly ascended in intensity from category C6 to M4, a trend that could produce high-M or even X-class flares on July 22nd if the explosions continue apace. Solar flare alerts: SMS Text
DOUBLE DARK PLASMA ERUPTION: Two dark plumes of plasma flew into space on July 21st when a magnetic filament connected to sunspot AR3757 erupted. NASA’s Solar Dynamics Observatory recorded their exit:

The plasma is dark because it is cooler and denser than the hot sun underneath. As the dense plumes traveled outward through the sun’s atmosphere, they entrained even more plasma, forming the core of a coronal mass ejection (CME).
Shortly after the blast, SOHO coronagraphs recorded a halo CME leaving the sun. A preliminary NASA model of the CME predicts it will hit Earth during the late hours of July 24th. The CME’s arrival could spark a G1-class geomagnetic storm. Solar flare alerts: SMS Text
