Russians may be the first to reach the Sun by Irina Shlionskaya

Despite the fact that the Sun is our "native" star, to date no one has been able to examine it at a close range. Now helio-physicists of several countries are working to create devices that would allow them to approach the sun as close as possible and study the processes taking place there. It is possible that the first solar probe will be launched in Russia.

The idea of ​​sending a spacecraft to the sun originated in the Russian scientific community in the 1970 (under Brezhnev). It involved not a manned spacecraft, but rather a research probe that was to be sent to the Sun. At the time, however, this project seemed technically unfeasible. The real work on the device able to explore the Sun from an extremely small distance (30-40 solar radii), was commenced by the Russian scientists only in 2005. Later, the project was included in the federal space program.

Now experts of the Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation named after Pushkov (IZMIRAN), Physics Institute of the Academy of Sciences (FIAN) and other research institutions along with their colleagues from the "Space Agency" are working on the completion of the project of Interhelioprobe device. By the end of the year the NGO named after Lavochkin will complete design sketches to determine the composition of the research equipment and the appearance of the "solar spy" planned to be "delivered" in the space at the top of the rocket Soyuz-2. It is assumed that 17 units will be housed on board of the domestic probe. Since their combined weight must not exceed 120 kilograms, specialists will use the most advanced technology and materials for the construction of the equipment.

John O'Sullivan: Top Scientist Says new Solar Wobble to Prolong Global Cooling

As a new solar minimum takes our planet towards global cooling an increasing number of scientists give credence to a new theory blaming our Sun's wobble.

It started in 2007 when scientists saw that gravitational forces in our solar system may have a huge impact on Earth's climate. Professor Ivanka Charvátová, CSc. from the Geophysical Institute of the Czech Academy of Sciences, explains why there is suddenly so much interest in her theory in an exclusive interview with klimatskeptik.cz.

Professor Charvátová calls it Solar Inertial Motion (SIM) and she claims it will have serious impacts on our climate. She says a predictable "wobble" of our Sun called barycenter shift alters Earth's weather patterns. Few climatologists have yet studied this phenomenon. But the evidence supporting Professor Charvátová's SIM theory is becoming ever more compelling.

Our Wobbling Sun

Increased international interest in the SIM 'wobble effect' began after Australian scientist Dr. Richard Mackey published a paper addressing the effects of the barycenter shift in The Journal of Coastal Research in 2007. Mackey drew inspiration from the work of the late Rhodes Fairbridge.

Earth to face intense solar activity in 2012
Saturday, May 28th 2011, 6:26 AM EDT
Co2sceptic (Site Admin)
Intense solar activity expected next year can result in a wave of anthropogenic disasters. However, experts say Russia won’t be among the worst affected countries.

Medieval astronomers registered that the number of spots on the Sun`s surface varied from time to time and sometimes vanished completely. In 1843 German astronomer Heinrich Schwabe discovered that sunspots changed in quantity according to strict cycles, from 9 up to 13,7 years- every 11 years on average. We now know that the Sun needs this period of time to change its magnetic pole into the opposite. This leads to geomagnetic storms which have an impact on radio communication, climate and the ozone layer. Undoubtedly, these cycles also affect our health, though this mechanism has not yet been well studied. Over the past 2,5 years we have been experiencing a period of low solar activity when there is not a single spot on the sun`s surface. It`s quite a long time as usually this cycle lasts not more than a year. Director at the Institute of Space Studies for the Russian Academy of Sciences, Lev Zeleny, shared official statistics on the problem…

"In Canada and Alaska transformers used to run out of order in times of intense solar activity, but now we know how to cope with it. There is a special space weather bureau at NASA to monitor the situation and release forecasts before there are any changes in solar activity."

New paper: Increased solar activity caused far more global warming than assumed by the IPCC

Total Solar Irradiance (TSI) Astronomy & Astrophysics 529, A67 (2011)

A recent peer-reviewed paper published in Astronomy & Astrophysics finds that solar activity has increased since the Little Ice Age by far more than previously assumed by the IPCC. The paper finds that the Total Solar Irradiance (TSI) has increased since the end of the Little Ice Age (around 1850) by up to 6 times more than assumed by the IPCC. Thus, much of the global warming observed since 1850 may instead be attributable to the Sun (called "solar forcing"), rather than man-made CO2 as assumed by the IPCC.

A new approach to the long-term reconstruction of the solar irradiance leads to large historical solar forcing

Interacting Sunspots Spawn Gigantic Solar Flare by Nancy Atkinson
Thursday, April 21st 2011, 3:10 AM EDT

From a RAS press release:

The largest solar flare recorded in nearly five years was triggered by interactions between five rotating sunspots, say researchers who studied observations of the flaring region of the Sun taken by the Solar Dynamics Observatory over a period of five days. The flare occurred at 1.44am on February 15,2011, when the Sun released the largest recorded solar flare since December 2006 and the first flare of the current solar cycle to be classified as the most powerful “X-class”.

NASA: Solar Activity Heats Up

April 14, 2011: If you've ever stood in front of a hot stove, watching a pot of water and waiting impatiently for it to boil, you know what it feels like to be a solar physicist

Back in 2008, the solar cycle plunged into the deepest minimum in nearly a century. Sunspots all but vanished, solar flares subsided, and the sun was eerily quiet.

"Ever since, we've been waiting for solar activity to pick up," says Richard Fisher, head of the Heliophysics Division at NASA Headquarters in Washington DC. "It's been three long years."

Current prediction for the next sunspot cycle maximum gives a smoothed sunspot number maximum of about 62 in July of 2013. We are currently over two years into Cycle 24.

The predicted size would make this the smallest sunspot cycle in nearly 200 years.

Sunspot Cycle Is Double-Peaked, Say Astronomers

The famous 11-year solar cycle often has two peaks rather than one and now one astronomer says she knows why

Sunspots are cool, dark patches on the surface of the Sun. They are thought to be the result of a temporary suppression of convection by the internal writhings of the Sun's magnetic field. That's why the spots are cooler than their surroundings.

The size and number of sunspots famously follows an 11-year cycle, a phenomenon first pointed out by Heinrich Schwabe, a German amateur astronomer in 1843. But in 1967, Mstislav Gnevyshev at the Russian Academy of Sciences, pointed out that many of these cycles appear to have two peaks.

Major Solar Flare Erupts, May Make Auroras Visible in Northern U.S.by Tariq Malik

The sun unleashed another major solar flare Wednesday, a solar storm so powerful it could spawn dazzling northern lights displays that could be visible from even New York City.

The solar flare erupted at 6:23 p.m. EST (2323 GMT), letting loose a wave of charged particles that is aimed straight at Earth and should arrive in the next few days.

When it does, it could supercharge the Earth's aurora borealis -- also known as the Northern Lights -- when the particles interact with the planet's magnetic field and atmosphere. [Photos: Dazzling Auroras Seen by Northern Observers]
