ARLA/CLUSTER: Tempestade geomagnetica previsível este fim de semana com auroras boreais

[João Costa > CT1FBF]

Polar geomagnetic storms this week

Polar geomagnetic storms are possible on Nov. 18th and 19th in response to
a glancing blow from an incoming CME (coronal mass ejection).

Auroras could appear in northern-tier US states from Maine to Washington.
