M7-CLASS SOLAR FLARE : Sunspot AR2036 erupted on April 18th at 1307 UT, producing a strong M7-class solar flare.

An S1-class radiation storm is underway in the aftermath of the flare. However, this is a relatively minor storm which poses minimal threat to satellites and aircraft.

Of greater interest is a CME that emerged from the blast site. The Solar and Heliospheric Observatory recorded the storm cloud racing away from the sun at aproximately 800 km/s:

This CME could deliver a glancing blow to Earth’s magnetic field on April 20-21. Two or three minor CMEs traveling ahead of this one are expected to arrive on April 19-20, and the combined impacts could generate geomagnetic activity throughout the weekend. NOAA forecasters put the odds of a geomagnetic storm at 55% on Saturday, increasing to 75% on Sunday. High-latitude sky watchers should be alert for auroras. Solar flare alerts: textvoice

The Most Likely Armageddon Threat … Preventable for a Small Amount of Money

Well-known physicist Michio Kaku and other members of the American Physical Society asked Congress to appropriate $100 million to harden the country’s electrical grid against solar flares.  As shown below, such an event is actually the most likely Armageddon-type event faced by humanity.

Congress refused.

Kaku explains that a solar flare like the one that hit the U.S. in 1859 would – in the current era of nuclear power and electric refrigeration – cause widespread destruction and chaos.

Not only could such a flare bring on hundreds of Fukushima-type accidents, but it could well cause food riots globally.

Kaku explains that relief came in for people hit by disasters like Katrina or Sandy from the “outside”. But a large solar flare could knock out a lot of the power nationwide. So – as people’s food spoils due to lack of refrigeration – emergency workers from other areas would be too preoccupied with their own local crisis to help. There would, in short, be no “cavalry” to the rescue in much of the country.

In fact, NASA scientists are predicting that a solar storm will knock out most of the electrical power grid in many countries worldwide, perhaps for months.

News Corp Australia noted in February:

A 2009 study by the National Academy of Sciences warned that a massive geomagnetic assault on satellites and interconnected power grids could result in a blackout from which the nation may need four to 10 years to recover.

In May 2012, a US Geological Survey report estimated a 6 percent chance of another Carrington event [referring to the solar flare of 1859 which was so strong that telegraph lines, towers and stations caught on fire at a number of locations around the world, and sparks showered from telegraph machines] occurring in the next decade.

But we do not know whether or not the Carrington event was as bad as sunstorms get.

[University of Kansas physicist Adrian ] Melott proposed that material from a solar megaflare 10 times the strength of the Carrington kind bombarded this planet around the year 775.

This is not just a theoretical fear: the Earth has narrowly missed being crisped by a large solar flareseveral times in the last couple of years. For example, the Los Angeles Times reported last month:

Earth barely missed the “perfect solar storm” that could have smashed into our magnetic field and wreaked havoc with our satellite systems, electronics and power systems, potentially causing trillions of dollars in damage, according to data from NASA’s STEREO-A spacecraft.

If the solar onslaught had occurred just nine days earlier, it would have rivaled the 1859 Carrington event …

“Observations of such a solar superstorm during a very weak solar cycle indicate thatextreme events are not as infrequent as we imagine,” the authors wrote.
