Spaceweather.com has an implicit warning today:
FARSIDE SUNSPOTS: Right now, there are sunspots on the farside of the sun so big they are affecting the way the sun vibrates. Helioseismologists have detected their echoes in the latest farside map from NASA’s Solar Dynamics Observatory. Don’t be surprised if we see CMEs billowing away from the farside of the sun in the days ahead.
It may sound all fine and abstract and far away – and, at nine light-minutes, give or take, it’s a long ways away.
In human terms.
But another Carrington Event would leave our power grid virtually – or possibly physically – aflame.
