CME IMPACT: 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:
So far geomagnetic activity resulting from the impact has fallen short of storm levels, but this could change as Earth passes through the wake of the CME. High-latitude sky watchers should remain alert for auroras. on April 13-14.
"Slowly cross your eyes until the shadows merge," advises Perkins. "I find the shape of the lenticular cloud creating the rays as interesting as the rays themselves. The cloud is cylindrical and shrouded in a thin foggy shell."
