Back in the 1850's a solar flare known as the Carrington Event surged enough electrical current through the earth to cause telegraph lines to overheat and maybe even set small fires. In more recent times, smaller solar flares have caused regional blackouts in North America, apparently due to transformer failure. It is said that another Carrington Event sized flare could cause extensive damage to a full continental region of the planet. Efforts have been made to reduce the danger to the power grid. But the largest modern power grid transformers are said to be foreign made and take years to manufacture. So the danger of solar storms and X-class flares are supposed real.
Please use this thread to debunk or confirm the risk of solar flares to our electrical grid, and to post notices of pending or arriving flares.
I track flares over NASA's website, Spaceweather.com. Below is a snippet of today's edition:
INCREASING CHANCE OF FLARES: NOAA forecasters have boosted the odds of an X-flare today to 30%. Earth-facing sunspot AR3182 has developed an unstable 'beta-gamma-delta' magnetic field that poses a threat for strong explosions. Shortwave radio blackouts and Earth-directed CMEs are likely this week. Solar flare alerts: SMS Text.
WHERE THE ACTION IS: A new, hyperactive sunspot is emerging over the sun's southeastern limb: AR3184. This 10-hour movie from NASA's Solar Dynamics Observatory captured at least half-a-dozen eruptions, most of them M-class:
None of the debris plumes will hit Earth; the sunspot is not facing our planet. It will turn in our direction later this week. Meanwhile, amateur astronomers with solar telescopes should point their optics at the southeastern limb. It's where the action is. Solar flare alerts: SMS Text.
