EARTH’S MAGNETIC FIELD IS RINGING LIKE A BELL

EARTH’S MAGNETIC FIELD IS RINGING LIKE A BELL: This morning in Lofoten, Norway, a magnetic observatory picked up unusually pure low-frequency waves rippling around the Arctic Circle. Known as “pulsations continuous” (Pc), these rare magnetic oscillations can energize particles in our planet’s magnetosphere, boosting the brightness of auroras. Indeed, strong auroras are being seen right now in Scandinavia. Visit today’s edition of Spaceweather.com to learn what caused these Pc waves and to monitor the ongoing display.
