28 solar flares in the last seven days, and more may be coming

The sun has erupted more than two dozen times over the last week, sending radiation and solar material hurtling through space - and scientists say more eruptions may be coming.

This shouldn't be unusual. After all, we are technically at solar maximum, the peak of the 11-year cycle of the sun's activity. But this has been a noticeably mellow solar maximum, with the sun staying fairly quiet throughout the summer. So when our life-giving star suddenly let loose with 24 medium strength M-class solar flares and four significantly stronger X-class flares between Oct. 23 and Oct. 30, it felt like a surprise.

Many of the flares originated from sunspot AR1884, a particularly active region of the sun that is currently facing Earth, almost at the center of the star. If this region stays active, it will continue to hurl radiation and solar material our way for about another week until it rotates out of sight.

Strange Doings on the Sun

Strange Doings on the Sun

Sunspots, Which Can Harm Electronics on Earth, Are Half the Number Expected

Something is up with the sun.

Scientists say that solar activity is stranger than in a century or more, with the sun producing barely half the number of sunspots as expected and its magnetic poles oddly out of sync.

The sun generates immense magnetic fields as it spins. Sunspots—often broader in diameter than Earth—mark areas of intense magnetic force that brew disruptive solar storms. These storms may abruptly lash their charged particles across millions of miles of space toward Earth, where they can short-circuit satellites, smother cellular signals or damage electrical systems.

Based on historical records, astronomers say the sun this fall ought to be nearing the explosive climax of its approximate 11-year cycle of activity—the so-called solar maximum. But this peak is "a total punk," said Jonathan Cirtain, who works at the National Aeronautics and Space Administration as project scientist for the Japanese satellite Hinode, which maps solar magnetic fields.

"I would say it is the weakest in 200 years," said David Hathaway, head of the solar physics group at NASA's Marshall Space Flight Center in Huntsville, Ala.

Researchers are puzzled. They can't tell if the lull is temporary or the onset of a decades-long decline, which might ease global warming a bit by altering the sun's brightness or the wavelengths of its light.

One explanation might be that the Sun's internal magnetic environment constitutes a chaotic system. We can record and identify it's average behavior just like collecting climate data. Prediction OTOH becomes geometrically less accurate as you try to apply that data even a few cycles into the future.

Video: Sun has 'flipped upside down' as new magnetic cycle begins

The sun has "flipped upside down", with its north and south poles reversed to reach the midpoint of Solar Cycle 24, Nasa has said.

Now, the magnetic fields will once again started moving in opposite directions to begin the completion of the 22 year long process which will culminate in the poles switching once again.

There are a couple other threads this could go into ~ apply, but "archiving" here for now;
Concern grows over possibility of massive power surge
The sun releases a M1.7 class flare associated with a prominence eruption on April, 16, 2012. This visually spectacular explosion occurred on the sun's Northeastern limb and was not Earth directed.
EXCERPTS:
...
"We definitely think this is a risk," said Trevor Maynard, head of exposure management at Lloyd's of London. "It is one of those hazards you just know is going to happen, just like you know a major Miami hurricane will happen."
...
In the case of electronic pulses, the most sober warnings come from government weather scientists.

At a recent conference in Washington, William Murtagh of the federal Space Weather Prediction Center described the dangers of a massive solar storm that is, as the Lloyd's report on the issue says, "almost inevitable."

Such storms take place roughly every 150 years. The last one was 155 years ago.

During the "Carrington event" of 1859 — named after the English astronomer who observed it — a huge solar storm ejected a mass of particles and electromagnetic energy intense enough to induce a surge that knocked out the switching system of the New York Central Railroad below 125th Street and caused the control tower to catch fire. News reports told of telegraph wires going berserk.

But electricity was hardly the backbone of society in pre-Civil War America. Scientists fear such an occurrence now could cause chaos.

A preview of the potential damage came in 1989, when the Hydro-Quebec power grid in Canada collapsed in less than two minutes from a solar storm. Six million people were without power for nine hours.

A good read on context and effects of Solar weather.
Who Turned Out the Lights? The Coming Mega Sun Storm

At Delta Air Lines’ (DAL) operations center in Atlanta, meteorologists do more than monitor the usual wind, rain, and snow. They also keep a close eye out for a less common but potentially more dangerous phenomenon known as space weather. The sun’s eruptions can send billions of tons of superheated, electrically charged gas hurtling through the solar system. When these clouds hit the earth’s magnetic field, they can result in geomagnetic storms that disrupt electric power and communications systems.

Space weather can play havoc with air-to-ground communications. Delta and other airlines reroute dozens of flights a year to avoid affected areas. It’s “nearly always minor enough that flight time is not significantly impacted,” says Delta spokesman Morgan Durrant. Transpacific flights between Asia and the East Coast of the U.S. are the most likely to be affected. Don’t expect the pilot on such a flight to come on the intercom and announce the plane is turning to avoid a blast from outer space. Instead, he’ll say it’s because of weather, Durrant says, “which is an accurate characterization.”

Most people have no idea that combating the effects of geomagnetic storms is a part of doing business for industries worldwide. With enough warning time, operators of New York’s power grid can alter voltage and reduce transfers across the system to protect against the strong ground currents generated by the storms. Companies that rely on GPS services may delay drilling, mining, or land surveys when satellite communications are disrupted by space weather. But corporations and the federal government may not be prepared for a severe geomagnetic storm—akin to a 100-year flood—that could fry electrical equipment and wipe out power to major cities for weeks or longer.

From a small office in Boulder, Colo., William Murtagh and a small team at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center monitor the sun 24 hours a day, sending alerts to industries and foreign governments when space storms are on the way. Murtagh, the center’s program coordinator, is well-versed in the damage geomagnetic storms can cause. Perhaps the most formidable megastorm on record happened in 1859. Known as the Carrington Event, it lit up night skies from Hawaii to Australia and led to telegraph outages around the world. Of course, no one alive today was around for it. “It is in the human nature,” Murtagh says, “to assess the threat based on your own life span.”

Might chase down the EMP thread for this, later, but now;
Paul Singer: This threat is 'head-and-shoulders' above all others

Billionaire hedge fund manager Paul Singer has issued an unusual warning for investors, calling the threat of a widespread blackout from an electromagnetic surge the "most significant danger" in the world.
Called an "electromagnetic pulse" or EMP, the events can occur naturally from solar storms or artificially from a high-altitude explosion of nuclear weapons.
"While these pages are typically chock full of scary or depressing scenarios, there is one risk that is head-and-shoulders above all the rest in terms of the scope of potential damage adjusted for the likelihood of occurrence," Singer wrote to clients of his $24.8 billion Elliott Management on Monday in a standard investment update letter. "Even horrendous nuclear war, except in its most extreme form, can [be] a relatively localized issue, and the threat from asteroids can (possibly) be mitigated."

EXCERPT:

"There's been a giant magnetic explosion on the sun," Berger said. "Because it's pointed right at us, we'll at least catch some of the cloud" of highly energized and magnetized plasma that can disrupt Earth's magnetic sphere, which sometimes leads to temporary power grid problems.
Forecasters don't yet know when Wednesday's solar storm will arrive here and which part of the planet will be facing the sun and bear the brunt of the effects. It could arrive as early as Thursday morning or may take a few days.

Blank Sun -
EXCERPT:
Overview
The sun is almost completely blank. The main driver of all weather and climate, the entity which occupies 99.86% of all of the mass in our solar system, the great ball of fire in the sky has gone quiet again during what is likely to be the weakest sunspot cycle in more than a century. The sun's X-ray output has flatlined in recent days and NOAA forecasters estimate a scant 1% chance of strong flares in the next 24 hours. Not since cycle 14 peaked in February 1906 has there been a solar cycle with fewer sunspots. We are currently more than six years into Solar Cycle 24 and the current nearly blank sun may signal the end of the solar maximum phase. Solar cycle 24 began after an unusually deep solar minimum that lasted from 2007 to 2009 which included more spotless days on the sun compared to any minimum in almost a century.
