MSNBC The sun is coming off a low in its 11-year activity cycle, and Sunday's eruption serves as another sign that things are finally picking up. SpaceWeather.com says the event apparently started with a flare from a site known as sunspot 1092, the only significant sunspot group currently facing Earth. At about the same time, the observatory detected a huge magnetic filament of material rising up from the sun's northern hemisphere.
"In short, we have just witnessed a complex global eruption involving almost the entire Earth-facing side of the sun," SpaceWeather.com's Tony Phillips said.
Is this the start of something big? Some doomsayers are worried that the sun is on schedule for a 2012 (or 2013) apocalypse - but all the signs so far is that our nearest star is in the midst of a thoroughly normal cycle. As the sun heads toward Solar Max, you can expect the potential for disruption, as well as the potential for harmless light shows like the one some folks will see Tuesday night.
