ARLA/CLUSTER: Agarrem-se que isto vai "abanar":Possivel impacto de Ejeção de Massa Coronal

[João Costa > CT1FBF]

Possible CME impact today

*Space Weather* reports that a coronal mass ejection (CME) hurled into
space by the X1-flare of May 15 might deliver a glancing blow to Earth's
magnetic field on May 17

They say NOAA forecasters estimate a 40% chance of polar geomagnetic storms
when the cloud arrives. High-latitude sky watchers should be alert for
auroras.

Sunspot AR1748 has already unleashed four X-class solar flares, but it
might not be finished. The active region continues to grow beneath a
delta-class magnetic field that harbors energy for powerful eruptions. NOAA
puts the odds of another X-flare today at 60%.
