More radio blackouts, more satellite disruptions, more volcanic eruptions and strong earthquakes ahead…
NOAA models confirm that a Cannibal CME will strike our planet on Dec. 1st. Cannibal CMEs form when a fast CME sweeps up a slower CME ahead of it.
The combination contains intense, tangled magnetic fields that can do a good job sparking auroras when they reach Earth. If a Cannibal CME strikes Earth on Dec. 1st, as predicted, geomagnetic storm levels could reach category G3 (Strong).
So now what happens during a strong geomagnetic storm?
Earth could experience a strong (G3) geomagnetic storm this week. If so, here’s what we can expect. The last G3-class storm on Nov. 5th sparked not only bright auroras, but also deep-red SAR arcs around the world. Greg Redfern photographed this example from the Shenandoah National Park in Virginia:
SAR arcs look like auroras, but they are not. They are the glow of heat energy leaking into the upper atmosphere from Earth’s ring current system–a donut-shaped circuit carrying millions of amps around our planet. During the Nov. 5th geomagnetic storm, these red arcs were observed as far south as Texas and California.
