"CIRs are transition zones between fast- and slow-moving streams of solar wind. They contain magnetic fields and shock waves akin to those of CMEs. While CMEs require some sort of explosion on the sun, CIRs do not. They form gently from the sandwiching of solar wind streams--no solar flare required.
The arrival of the CIR on March 8th immediately caused a G1-class (Minor) storm, intensifying to category G2 (Moderate) on March 9th. Sky watchers in Iceland, Canada and multiple US states from New York to Utah saw the geomagnetic glow.
A fast-moving solar wind stream has arrived on the heels of the CIR. This is the same stream that created the CIR in the first place by compressing a region of slower solar wind ahead of it. Blowing almost 600 km/s, the fast stream could cause additional category G1 (Minor) storms on March 10th.. "

GEOMAGNETIC GROUND CURRENTS IN NORTH AMERICA: Space weather isn't all about the sky. It's in the ground, too. On April 16th, a severe geomagnetic storm caused electricity to flow through the rocks and soil of North America. Red zones in this animated map from NOAA show where voltages were greatest:

Geoelectric voltages were more than 70 times normal in the Appalachian mountain range, northern Minnesota, and northwestern Canada. Texas and other western US states were relatively unscathed.
Researchers track ground currents because in extreme cases they can cause power outages like the Great Québec Blackout of March 13, 1989. This week's storm wasn't intense or long-lasting enough to bring down power grids, but NOAA's maps show where power stations are most vulnerable.
"Generally, geoelectric amplitudes are high over metamorphic rock, such as in the Appalachians and northern Minnesota," explains Jeffrey Love of the US Geological Survey (USGS). "They are usually low over sedimentary rock such as in Texas and northwest of the Appalachians."
