The Sun exploded late Sunday, January 22, with a massive flare, an Earth-directed coronal mass ejection, and a burst of fast-moving, highly energetic protons. The latter has caused the strongest solar radiation storm since September 2005 according to NOAA's Space Weather Prediction Center.
NASA models predict that the CME is moving at almost 1,400 miles per second, and are right now pummeling Earth's protective magnetosphere. This has the potential to provide lovely auroral displays, possibly at lower latitudes than normal... and HORRIBLE DOOOOM! Well, it is a threat to satellites, the Space Station, and so forth. Check it out:
That flash you see in the blue portion is many dozens of times the size of Earth; the eruption you see in the red is... well, larger than the Sun. They're not the biggest ones ever or anything like that, but the exciting part of this event is that the ejection is pointed at us.
We've never endured a period of high solar activity with today's level of dependence upon communication technology, so it'll be interesting to see how this affects communications.

Well thank god Mercury isn't in retrograde at the same time.
How fast do flares affect the earth, do you know? As in, what is the time frame for the effects to reach earth?
Reason I'm asking is that my cell phone internet was down all evening yesterday. It finally came back up this a.m.
And speaking of light: this makes me wonder if we had hella strong northern lights shows, also....
so does this kind of thing cause any bodily harm? or just a disruption in satelites? that video is just beautiful, though!
