ARLA/CLUSTER: Esperadas Tempestades Geomagneticas de classe G1 e G2 para hoje e amanhã

[João Costa > CT1FBF]

Geomagnetic storms likely this week

A large hole has opened in the sun's atmosphere, and it is spewing a stream
of solar wind toward Earth. Estimated time of arrival: Oct. 24th.

First contact with the gaseous material is expected to produce minor
G1-class geomagnetic storms, intensifying to moderately strong G2-class
storms on Oct. 25th as Earth moves deeper into the stream.

Arctic sky watchers can expect to witness bright auroras. The lights could
descend to lower latitudes as well, with sightings in northern-tier US
states along a line from Maine to Washington.
