Ted’s essays

possible CME hit here December 1st

This could be an important event to prepare for. If a massive Coronal Mass Ejection (solar flare) strikes the Earth as is a predicted possibility, electronics could be devastated, along with our entire electrical distribution system.

This might be an auspicious time to put some effort into a Faraday Cage or two … and employ them for electronic stuff you value highly.

I don’t want to overstate the warning, but I think it prudent to put some time in Friday protecting our electronics and have at least half a plan for a complete grid-down power failure.

Hope and Faith are not plans.

GEOMAGNETIC STORM WATCH (G3): Three and perhaps four CMEs are heading for Earth following a series of explosions on the sun this week. Estimated time of arrival: Nov. 30th and Dec. 1st. The biggest of the CMEs, launched on Nov. 28th, could sweep up some of the earlier, lesser ones, forming a Cannibal CME capable of sparking strong G3-class geomagnetic storms with mid-latitude auroras. Aurora alerts: SMS Text

ALMOST-X CLASS SOLAR FLARE: Sunspot AR3500 erupted on Nov. 28th (1950 UT), producing an M9.8-class solar flare (only percentage points below category X). NASA’s Solar Dynamics Observatory recorded the blast:

A pulse of extreme ultraviolet radiation blacked out shortwave radio communications across the South Pacific Ocean and parts of the Americas: map. Mariners and ham radio operators may have noticed loss of signal at frequencies below ~20 MHz for as much as an hour after the flare.

Of greater interest is the CME. The explosion hurled one directly toward Earth. This SOHO coronagraph movie shows a halo cloud expanding in our direction faster than 800 km/s (1.8 million mph):

According to a NASA model, this CME will strike Earth midday (UT) on Dec. 1st. It might sweep up one of several slower CMEs ahead of it. If so, it could form a Cannibal CME capable of causing a strong G3-class geomagnetic storm. CME alerts: SMS Text
