ARLA/CLUSTER: Erupção global no Sol

[João Costa > CT1FBF]

Global eruption on the sun

* Space Weather* reports on what may be an interconnected global eruption
on the Sun

Solar activity is high and intensifying. New sunspot AR1882, which rotated
over the sun's eastern limb earlier October 25, promptly unleashed an
X1-class solar flare, adding to a series of lesser flares already underway
from sunspots AR1875 and AR1877.

NASA's Solar Dynamics Observatory recorded a bright flash of extreme UV
radiation from the X1 flare, which peaked at 08:01 UT on Oct. 25th:

There may be more to this flare than meets the eye. The X1-flare was
bracketed by two erupting magnetic filaments, each located hundreds of
thousands of kilometers from AR1882. In other words, the X1 flare might
have been just one piece of an interconnected global eruption.

More flares are in the offing. There are now three sunspot groups on the
Earthside of the sun capable of strong eruptions: AR1875, AR1877 and AR1882.
