ARLA/CLUSTER: Oscilação incomum do Campo Magnético Terrestre detectada a 22 de Fevereiro

[João Costa > CT1FBF]

 Unusual oscillations in Earth's magnetic field

Yesterday morning (22 Feb) 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.
