Solar wind alert

NOAA forecasters estimate a 60% chance of minor G1-class geomagnetic storms on June 1st, increasing to 65% on June 2nd, when a stream of high-speed solar wind is expected to reach Earth.

The last time this gaseous stream lashed our planet's magnetic field, almost a month ago, it sparked bright ribbons of purple light (a.k.a. "STEVE") seen from multiple US states.
