Big blob of plasma from sun will come near Earth tomorrow, could disrupt magnetic field (video embedded)

From the Washington Post’s Sun shoots a fastball at Earth, but minimal impact expected:

A huge sunspot unleashed a blob of charged plasma Thursday that space weather watchers predict will blast past the Earth on Sunday. Satellite operators and power companies are keeping a close eye on the incoming cloud, which could distort the Earth’s magnetic field and disrupt radio communications, especially at higher latitudes.

“Our simulations show potential to pack a good punch to Earth’s near-space environment,” said Antti Pulkkinen of the Space Weather Laboratory at NASA’s Goddard Space Flight Center in Greenbelt.

But, he added, “We’re not looking at an extreme event here.”

The front edge of the burst should arrive Sunday morning [. . .]

I’m not sure what I’m looking at, but this is satellite imager of the sun belching out the plasma blob on Thursday:

The blob is apparently moving at more than 2 million miles per hour.
