Massive Explosion On the Sun

Endoflow2010 sends word of an enormous eruption that occurred on the Sun this morning. Phil Plait describes it thus: "What you’re seeing here is a solar flare (an enormous explosion of pent-up magnetic energy) coupled with a prominence (a physical eruption of gas from the surface). This event blasted something like a billion tons of material away from the Sun. Note the size of it, too: while it started from a small region on the Sun’s surface, it quickly expanded into a plume easily as big as the Sun itself! I’d estimate its size at well over a million kilometers across." The attached video is well worth watching.

    If you want a more complete coverage of the event (not to mention a few more tasty videos) then there is a much better write up at The Sun Today .org which you should take a peek at.

    I've worked in the NOC for 2 major telcos. Neither has any plan for solar flare events. When I brought it up I was literally laughed at. When I pulled down NASA's space weather data that rates solar flares effects on earth, correlated it with our network alarms and was able to show that given a certain size flare we were almost guaranteed to have a 10% increase in network alarms... a Huge spike only eclipsed by major Thunderstorms and hurricanes, I was laughed at even harder.

    It's not profitable to plan for rare events. It's profitable to plan for common events and let the insurance cover the catastrophes. The public interest be damned.

    This is sad but true. I've been in the space weather business for 40 years, and was involved with the aftermath of the large geomagnetic storm that took out the power generator in Quebec mentioned in another post. There was quite a flurry of meetings with various energy agencies about what was to be done. Bottom line was that the space weather groups were asking that the power industry pay a lot of money for predictions and warnings that were not of the highest reliability (another sad-but-true fact). After the risk-management boys got done crunching the numbers, the power industry decided that it was cheaper to ignore the problem and live with the fact that they might lose a generator every 11 years or so. The insurance folks will pick up the monetary tab, and the Great Unwashed Public (also known as "the customers") will shiver in their dark unheated homes until things get fixed and like it. As long as these events can be legally treated as unpredictable "acts of God" there is no impetus for the power companies to do anything about them, free market be damned.
