Here's the source page I assume:

There are images for different "wavelength channels" there btw, the OP one seems to be "193":

Tip: Hover over the wavelength labels underneath the set of images to change the thumbnail image.

UPD Article from Google:

A large coronal hole spewing out lots of fast solar wind has rotated into a geoeffective position, that is, a prime position for affecting Earth. So that stream of solar stuff is due to blast Earth’s magnetic field, meaning more geomagnetic storms … meaning more auroras! The stream is expected to reach us by midday UTC tomorrow (December 4). It’s expected to cause a G2 (moderate) geomagnetic storm . The rush of solar particles should continue into the next day (December 5) with slightly calmer storms at the G1 (minor) level.
