Mystery: Sun grows strangely quiet, lowest activity in 100 years

December 14, 2013SPACEThe sun’s current space-weather cycle is the most anemic in 100 years, scientists say. Our star is now at “solar maximum,” the peak phase of its 11-year activity cycle. But this solar max is weak, and the overall current cycle, known as Solar Cycle 24, conjures up comparisons to the famously feeble Solar Cycle 14 in the early 1900s, researchers said. “None of us alive have ever seen such a weak cycle. So we will learn something,” Leif Svalgaard of Stanford University told reporters here today (Dec. 11) at the annual meeting of the American Geophysical Union. The learning has already begun. For example, scientists think they know why the solar storms that have erupted during Solar Cycle 24 have caused relatively few problems here on Earth. The sun often blasts huge clouds of superheated particles into space, in explosions known as coronal mass ejections (CMEs). Powerful CMEs that hit Earth squarely can trigger geomagnetic storms, which in turn can disrupt radio communications, GPS signals and power grids. 
But such effects have rarely been seen during Solar Cycle 24, even though the total number of CMEs hasn’t dropped off much, if at all. The explanation, researchers said, lies in the reduced pressure currently present in the heliosphere, the enormous bubble of charged particles and magnetic fields that the sun puffs out around itself. This lower pressure has allowed CMEs to expand greatly as they cruise through space, said Nat Gopalswamy of NASA’s Goddard Space Flight Center in Greenbelt, Md. Indeed, Solar Cycle 24 CMEs are, on average, 38 percent bigger than those measured during the last cycle — a difference with real consequences for folks here on Earth. “When the CMEs expand more, the magnetic field inside the CMEs has lower strength,” Gopalswamy said. “So when you have lower-strength magnetic fields, then they cause milder geomagnetic storms.” –Space.com

    A cooling period may have begun. According to some, it has arrived. If you look at the recent posts on this site, something is going on with the weather. I have read that some weather experts believe that we could see a mini ice age and there are some who disagree. The theory is that lower sunspot activity leads to more cosmic rays hitting the earth causing more clouds and a cooler climate. It is believed that this cooling cycle may last a decade? Those who seem to know are saying a cooling period that could last a decade is coming, caused by low sun spot activity. And the articles I read are as early as 2011.

    Look at the snow in Jerusalem and other places in the mid east and here in the usa.
    Think we need to stock some warm clothes and socks…….if this is true

      “Think we need to stock some warm clothes and socks…….if this is true” *Sigh* Just moved from freezing Canada to Central America. The locals say they haven’t seen rain like this since the 1950′s, and its cooler here than normal, too. We turned on the vehicle’s heater yesterday. I refuse to put on a sweater, dagnabit!!

    I believe this is a calm before the storm. Silence in the heavens right before a really bad event occurs.

    It may be a good idea to invest in winter gear, good wood stove and pile of wood, and cold hardy fruit & vegetable plants.

    • I advise all to do exactly that. We should all be preparing for very harsh winters with prolonged periods of cold spells.

      Add to that high possibility of prolonged emergency periods without electricity; I advise ppl to stock up on food, water, alternative energy source and protection. As James have mentioned above, this may be just a come before huge storm – for which we are overdue anyway. But either way, you can’t go wrong when you hope for the best but prepare for the worst! :)
