The Terminator

This from 2 March https://www.spaceweather.com/

FARSIDE SUNSPOT: NASA’s STEREO-A spacecraft is monitoring a large ultraviolet hotspot behind the sun’s northeastern limb. It is definitely a concentration of hot plasma and magnetic fields; it might be an active sunspot. We will soon find out as it rotates into view before the end of the week. Solar flare alerts: SMS Text.

THE TERMINATION EVENT HAS ARRIVED: Something big just happened on the sun. Solar physicists Scott McIntosh (NCAR) and Bob Leamon (U. Maryland-Baltimore County) call it “The Termination Event.”

“Old Solar Cycle 24 has finally died–it was terminated!” says McIntosh. “Now the new solar cycle, Solar Cycle 25, can really take off.”

The “Termination Event” is a new idea in solar physics, outlined by McIntosh and Leamon in a December 2020 paper in the journal Solar Physics. Not everyone accepts it–yet. If Solar Cycle 25 unfolds as McIntosh and Leamon predict, the Termination Event will have to be taken seriously.
