SOLAR ACTIVITY: Sunspot AR1339 is crackling with M-class solar flares, unleashing at least five of them in the past 24 hours. The blasts have been coming with such thick frequency that photographer Randy Shivak of Elyria, Ohio, was able to catch one in action on Nov. 5th:
"Looking like iron filings around a bar magnet, sunspot group 1339 showed itself in the throes of a solar flare," says Shivak.
Even bigger eruptions are possible before the weekend is over. AR1339 has a delta-class magnetic field that harbors energy for X-class flares. The sunspot is turning toward Earth, so the odds of a geoeffective flare are increasing. Solar flare alerts: text, voice.
