Some scientists believe bursts of solar activity cause natural disasters on our planet, but until now the star has been too difficult to reach or explore in any detail. Some Russian researchers think they have the solution. ­Volcanic eruptions, earthquakes, tsunamis -- apocalyptic pictures are becoming an ordinary part of news bulletins across the globe. And scientists are not giving out reassuring forecasts. "Unfortunately, we're expecting more severe cataclysms which may lead to large-scale human losses and destruction," says Baku-based Professor Elchin Kakhalilov of the Global Network for the Forecasting of Earthquakes.

"I'm talking about even a possible shift of the centers of our entire civilization." The change in the Earth's seismic activity coincides with the rise of activity on the sun. Scientists have been witnessing gigantic bursts of plasma on its surface and say they are affecting our planet, even though it is over 90 million miles away.

Brits to shut grid for solar flare by Sallie Don and Amos Aikman

BRITAIN is preparing to invoke emergency powers to turn off its electricity to shield the country from the worst effects of the biggest solar flare in 150 years.

The British government has been warned that a massive surge of energy from the sun could hit the Earth in the next 18 months. In a worst-case scenario, it could blow out the national grid and leave parts of the country without electricity for months.

Australian electricity experts are not convinced the solar flare will have anywhere near the catastrophic effects predicted in Britain and think any electromagnetic surge will go largely unnoticed.

Head of electrical engineering at the University of Technology, Sydney, Jianguo Zhu, said communication networks such as the internet would be the systems most likely to suffer from any solar flare. "The power grid is run by a computer network, which could be affected by the surge, which may cause blackouts," Professor Zhu told The Australian.

Next solar cycle may be weakest for centuries by Kate Taylor, TG Daily

Sunspots could be set to disappear altogether after the next solar maximum, new studies indicate

Right now, the sun is in the middle of Cycle 24, and is due to reach a maximum in 2013. The next cycle would be expected to start in around 2020.

But separate examinations of the sun's interior, surface and upper atmosphere all indicate that the next cycle will be significantly weakened.

Indeed, we may be heading into what's known as a 'grand minimum' - a period of unusually low solar activity. The last such, known as the Maunder Minimum, took place between 1645 and 1755. Almost no sunspots were observed during this time.

The studies drew their conclusions from a missing jet stream in the interior of the sun, vanishing sunspots on its surface and changes in the corona and near the poles.

The National Solar Observatory (NSO) says that, based on 13 years of observations, sunspots are weakening. There have been fewer during the present cycle - and, if the trend continues, there may be none at all in the next.

Physicists say sunspot cycle is 'going into hibernation'

What may be the science story of the century is breaking this evening, as heavyweight US solar physicists announce that the Sun appears to be headed into a lengthy spell of low activity, which could mean that the Earth – far from facing a global warming problem – is actually headed into a mini Ice Age.

The announcement made on 14 June (18:00 UK time) comes from scientists at the US National Solar Observatory (NSO) and US Air Force Research Laboratory. Three different analyses of the Sun's recent behaviour all indicate that a period of unusually low solar activity may be about to begin.

The Sun normally follows an 11-year cycle of activity. The current cycle, Cycle 24, is now supposed to be ramping up towards maximum strength. Increased numbers of sunspots and other indications ought to be happening: but in fact results so far are most disappointing. Scientists at the NSO now suspect, based on data showing decades-long trends leading to this point, that Cycle 25 may not happen at all.

Sun's Fading Spots Signal Big Drop in Solar Activity by Denise Chow, Space.com

Some unusual solar readings, including fading sunspots and weakening magnetic activity near the poles, could be indications that our sun is preparing to be less active in the coming years.

The results of three separate studies seem to show that even as the current sunspot cycle swells toward the solar maximum, the sun could be heading into a more-dormant period, with activity during the next 11-year sunspot cycle greatly reduced or even eliminated.

The results of the new studies were announced today (June 14) at the annual meeting of the solar physics division of the American Astronomical Society, which is being held this week at New Mexico State University in Las Cruces.

"The solar cycle may be going into a hiatus," Frank Hill, associate director of the National Solar Observatory's Solar Synoptic Network, said in a news briefing today (June 14).

The studies looked at a missing jet stream in the solar interior, fading sunspots on the sun's visible surface, and changes in the corona and near the poles. [Photos: Sunspots on Earth's Star]

"This is highly unusual and unexpected," Hill said. "But the fact that three completely different views of the sun point in the same direction is a powerful indicator that the sunspot cycle may be going into hibernation."

Sunspots are temporary patches on the surface of the sun that are caused by intense magnetic activity. These structures sometimes erupt into energetic solar storms that send streams of charged particles into space.

Since powerful charged particles from solar storms can occasionally wreak havoc on Earth's magnetic field by knocking out power grids or disrupting satellites in orbit, a calmer solar cycle could have its advantages.

Astronomers study mysterious sunspots because their number and frequency act as indicators of the sun's activity, which ebbs and flows in an 11-year cycle. Typically, a cycle takes roughly 5.5 years to move from a solar minimum, when there are few sunspots, to the solar maximum, during which sunspot activity is amplified.

New Insights on How Solar Minimums Affect Earth by Karen C. Fox, NASA's Goddard Space Flight Center

Since 1611, humans have recorded the comings and goings of black spots on the sun. The number of these sunspots waxes and wanes over approximately an 11-year cycle -- more sunspots generally mean more activity and eruptions on the sun and vice versa. The number of sunspots can change from cycle to cycle, and 2008 saw the longest and weakest solar minimum since scientists have been monitoring the sun with space-based instruments.

Observations have shown, however, that magnetic effects on Earth due to the sun, effects that cause the aurora to appear, did not go down in synch with the cycle of low magnetism on the sun. Now, a paper in Annales Geophysicae that appeared on May 16, 2011 reports that these effects on Earth did in fact reach a minimum -- indeed they attained their lowest levels of the century -- but some eight months later. The scientists believe that factors in the speed of the solar wind, and the strength and direction of the magnetic fields embedded within it, helped produce this anomalous low.

"Historically, the solar minimum is defined by sunspot number," says space weather scientist Bruce Tsurutani at NASA's Jet Propulsion Laboratory in Pasadena, Calif., who is first author on the paper. "Based on that, 2008 was identified as the period of solar minimum. But the geomagnetic effects on Earth reached their minimum quite some time later, in 2009. So we decided to look at what caused the geomagnetic minimum."

Solar Climate Change: 'Major Result' on Sunspot Cycle Announced : Now Updated with links

Astronomers will unveil a "major result" on Tuesday (June 14) regarding the sun's 11-year sunspot cycle.

The announcement will be made at a solar physics conference in New Mexico, according to an alert released today (June 10) by the American Astronomical Society. The discussion will begin at 1 p.m. EDT (1700 GMT).

Currently, the sun is in the midst of its Solar Cycle 24, the 24th cycle since observations began.

Recently, the sun has begun rousing itself from an extended quiescent period. Over the past several months, our star has unleashed several immensely powerful flares and sent huge volumes of solar plasma rocketing toward Earth, in massive eruptions known as coronal mass ejections (CMEs).

In the near future, the flares and CMEs should get more frequent and more intense. Researchers predict that solar activity will peak sometime in 2013 or 2014.

America's space agency NASA has reported on Tuesday an unusual explosion on the surface of the Sun, which according to the US National Weather Service (NWS) released a solar flare that would likely disrupt satellite, communication and power facilities on Earth over the next two days

The NWS added in its statement that a similar explosion of the same magnitude occurred five years ago, with the present one measured by NASA as M-2 or medium sized solar flare that carries "a substantial coronal mass ejection (CME) ... and is visually spectacular."

NASA said in a statement that the observed solar flare reached its peak at 0341 AEST on Tuesday, in which "the large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface."

That spontaneous solar activity, however, is expected to cause minimal effect on Earth since the impact of the explosion will not directly travel towards the planet's direction.

At most, the NWS said that the eruption will likely bring minor (G1) to moderate (G2) levels of geomagnetic storm activities, which could disturb Earth's power grids and global positioning systems that heavily rely on satellite communications.
