CME IMPACT

From Space Weather.com

 

 A coronal mass ejection (CME) swept past Earth on April 13th around 22:55 UT. The impact rattled Earth's magnetic field and induced electrical currents in the ground around the Arctic Circle. Rob Stammes recorded the effects of the impact from a geophysical monitoring station at the Polar Light Center in Lofoten, Norway.

"On my instruments there was a clear signature of the incoming coronal mass ejection," says Stammes. "The impact was not as strong as expected, but there were nice variations on my magnetometer and ground current instruments. There were also Northern Lights."

Geomagnetic activity resulting from the impact never reached storm levels, but many bright auroras were nevertheless observed around the Arctic Circle. NOAA (National Oceanic and Atmospheric Administration)  forecasters estimate a 20% chance of storms tonight as Earth exits the CME's wake.
