    The Nation ^ | November 11, 2015 | Sam Khoury
    New studies flip climate-change notions upside down The sun will go into "hibernation" mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society's annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it - the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova's model is said to have near-perfect accuracy. So what is a "solar minimum"? Our sun doesn't maintain a constant intensity. Instead, it cycles in spans of approximately 11 years....
  • Giant 'Hole' in Sun Is 50 Earths Wide [400,000 miles wide]

    10/16/2015 11:43:44 AM PDT · by ETL · 54 replies ^ | October 15, 2015 | Sarah Lewin
    The sun has sprung a leak: A hole in the topmost layer of the sun and its magnetic field, the size of 50 Earths, is letting loose an ultrafast solar wind that has kicked off several nights of auroras down on Earth. A new image, from NASA's orbiting Solar Dynamics Observatory, reveals the enormous hole as it was Oct. 10, taken at an ultraviolet wavelength unseen by the human eye. To an ordinary observer, the gaping hole would be invisible, though you should NEVER stare at the sun because serious eye damage can result. The gap in the sun's magnetic...

    Explanation: Not once, but twice the International Space Station transits the Sun on consecutive orbits of planet Earth in this video frame composite. The scene was captured on August 22 from a single well-chosen location in Schmalenbeck, Germany where the ISS created intersecting shadow paths only around 7 kilometers wide. Crossing the solar disk in a second or less, the transits themselves were separated in time by about 90 minutes, corresponding to the space station's orbital period. while the large, flare-producing sunspot group below center, AR 2043, remained a comfortable 150 million kilometers away, the distance between camera and orbiting...

  • Solar activity predicted to fall 60% in 2030s, to 'mini ice age' levels: Sun driven by double dynamo

    07/09/2015 1:51:30 PM PDT · by Ken H · 67 replies
    Summary: A new model of the Sun's solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun's 11-year heartbeat. The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Predictions from the model suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the 'mini ice age' that began in 1645. Results will be presented today by Prof Valentina Zharkova at the National Astronomy Meeting in Llandudno.

    It’s been two years since former vice president Al Gore claimed the Arctic would be free of sea ice, and despite fears of a hastening polar “death spiral” earlier this year, the north pole looks like it could have near normal ice coverage this summer. After experiencing its lowest maximum sea ice extent on record, the Arctic ice coverage has rebounded and is currently within its normal 30-year range. Near the end of May 2015, experts warned the Arctic “ice extent was at daily record low levels” because of early ice melting in the Bering Sea and low ice conditions...

    Climate experts warn the amount of light and warmth released by the sun is nosediving to levels "not seen for centuries". They fear a repeat of the so-called 'Maunder Minimum' which triggered Arctic winter whiteouts and led to the River Thames freezing 300 years ago. The Met Office-led study warns although the effect will be offset by recent global warming, Britain faces years of unusually cold winters.

    The Maunder Minimum (also known as the prolonged sunspot minimum) is the name used for the period roughly spanning 1645 to 1715 when sunspots became exceedingly rare, as noted by solar observers of the time. Like the Dalton Minimum and Spörer Minimum, the Maunder Minimum coincided with a period of lower-than-average global temperatures. During one 30-year period within the Maunder Minimum, astronomers observed only about 50 sunspots, as opposed to a more typical 40,000-50,000 spots.

    Ice Ages Blamed on Tilted Earth By Michael Schirber LiveScience Staff Writer posted: 30 March 2005 In the past million years, the Earth experienced a major ice age about every 100,000 years. Scientists have several theories to explain this glacial cycle, but new research suggests the primary driving force is all in how the planet leans. The Earth’s rotation axis is not perpendicular to the plane in which it orbits the Sun. It's offset by 23.5 degrees. This tilt, or obliquity, explains why we have seasons and why places above the Arctic Circle have 24-hour darkness in winter and constant...

    Monica Bobra, Scientific American December 16, 2014A couple of months ago, the sun sported the largest sunspot we've seen in the last 24 years. This monstrous spot, visible to the naked eye (that is, without magnification, but with protective eyewear of course), launched more than 100 flares. The number of the spots on the sun ebbs and flows cyclically, every 11 years. Right now, the sun is in the most active part of this cycle: we're expecting lots of spots and lots of flares in the coming months. Usually, the media focuses on the destructive power of solar flares —...

    Explanation: Solar active region AR2192 was the largest recorded sunspot group of the last 24 years. Before rotating off the Earth-facing side of the Sun at the end of October, it produced a whopping six energetic X-class flares. Its most intense flare was captured on October 24 in this stunning view from the orbiting Solar Dynamics Observatory. The scene is a color combination of images made at three different wavelengths of extreme ultraviolet light; 193 angstroms shown in blue, 171 angstroms in white, and 304 angstroms in red. The emission, from highly ionized Iron and Helium atoms, traces magnetic field...

Captured in this sharp telescopic image from October 22nd the complex AR 2192 is beautiful to see, a sprawling solar active region comparable in size to the diameter of Jupiter. Like other smaller sunspot groups, AR 2192 is now crossing the Earth-facing side of the Sun and appears dark in visible light because it is cooler than the surrounding surface. Still, the energy stored in the region's twisted magnetic fields is enormous and has already generated powerful explosions, including two...

    During the past 48 hours, monster sunspot AR2192 has unleashed seven M-class solar flares. The most powerful of the bunch (Oct 22nd at 0159 UT) was an M9-class eruption that almost crossed the threshold into X-territory. NASA's Solar Dynamics Observatory recorded the extreme ultraviolet flash. UV radiation from the flare ionized Earth's upper atmosphere, causing a brief blackout of HF radio communications on the dayside of Earth (e.g., parts of Asia and Australia). In addition, the explosion might have hurled a CME into space. Confirmation awaits the arrival of coronagraph data from the Solar and Heliospheric Observatory (SOHO). Stay tuned...

    Both observational and proxy records of climate change often show quasi periodic variations similar to solar activity cycles over a wide range of time scales. However, the detailed mechanism and the extent of the influence of solar activity on climate change have not been clearly understood. Although the exact role of each of solar parameters on climate change has not been quantitatively clarified, several possible mechanisms are proposed; such as the forcing through total (e.g. Lean et al., 1995) and spectral irradiance (e.g. Haigh 1996; Kodera and Kuroda, 2005), solar wind (e.g. Tinsley, 1996) and the galactic cosmic rays...

    A giant sunspot – a magnetically strong and complex region on the sun's surface – has just appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation.

    Explanation: Sunsets may be the most watched celestial event, but lately sunsets have even offered something extra. A sunspot so large it was visible to the naked eye is captured in Swiss skies in this sunset scene from January 5, crossing left to right near the center of a solar disk dimmed and distorted by Earth's dense atmosphere. Detailed views reveal a large solar active region composed of sunspots, some larger than planet Earth itself. Cataloged as active region AR 1944, on January 7 it produced a substantial solar flare and a coronal mass ejection (CME) forecast to reach Earth....

    To complicate the riddle, the sun also is undergoing one of its oddest magnetic reversals on record. Normally, the sun's magnetic north and south poles change polarity every 11 years or so. During a magnetic-field reversal, the sun's polar magnetic fields weaken, drop to zero, and then emerge again with the opposite polarity. As far as scientists know, the magnetic shift is notable only because it signals the peak of the solar maximum, said Douglas Biesecker at NASA's Space Environment Center. But in this cycle, the sun's magnetic poles are out of sync, solar scientists said. The sun's north magnetic...
  • Solar Activity Ramps Up as Giant Sunspot Group Turns to Face Earth

    While old Sol had been fairly quiet for the time where it was supposed to be active in its normal 11-year cycle, only recently has activity ramped up with increased flares and sunspots. During 2013, there has been intermittent strong activity (like this and this in May), but the activity since mid-October is really the first extended period of activity. Speaking of sunspots, a huge group called designated as AR 1890 has turned to face Earth. Thanks to astrophotographer Ron Cottrell for capturing the group today, above. reports that this sunspot has a trend of producing very brief flares....

    The fall-out from a grid-down scenario would be absolutely devastating, as noted by a spokesman for the Center for Security Policy who recently responded to the potential for EMP capable weapons being deployed over the United States: And experts forecast if such an attack were a success, it effectively could throw the U.S. back into an age of agriculture. “Within a year of that attack, nine out of 10 Americans would be dead, because we can’t support a population of the present size in urban centers and the like without electricity,” said Frank Gaffney, president of the Center for Security...
  • Sun Unleashes Another Solar Storm Aimed at Earth

    The sun fired off an intense solar storm at Earth Wednesday (Aug. 21) — the second in two days — hurtling billions of tons of charged particles at our planet, but should not pose a threat to people on the ground, NASA says. The solar eruption, called a coronal mass ejection, occurred yesterday at 1:24 a.m. EDT (0524 GMT) and sent charged particles streaking outward at 380 miles per second. That's just over 1.3 million mph (2.2 million km/h). The solar fallout from the sun storm is expected to reach Earth within the next three days.
  • What Will Happen When the Sun’s Magnetic Poles Reverse?

    08/06/2013 4:25:54 PM PDT · by BenLurkin · 85 replies ^ | August 6, 2013 | by Nancy Atkinson on
    The flip-flopping of the Sun’s magnetic field takes place at the peak of each solar activity cycle when the Sun’s internal magnetic dynamo reorients itself. When the field reversal happens, the magnetic field weakens, then dies down to zero before emerging again with a reversed polarity. While this is not a catastrophic event, the reversal will have effects, said solar physicist Todd Hoeksema, the director of Stanford University’s Wilcox Solar Observatory, who monitors the Sun’s polar magnetic fields. “This change will have ripple effects throughout the Solar System,” he said.

    About to go to space? Better postpone your trip The solar magnetic field will completely "flip" within the next three or four months, according to NASA.The dramatic-sounding event happens every 11 years. The Sun's magnetic activity follows a cycle, and as it reaches a maximum the poles weaken, reversing polarity. In June last year, the Sun's northern polar field became more positively charged than the southern polar field - what's called a "reversal" of polarity. What's called a "flip" is considered to have taken place when the both fields change polarity. The Sun's magnetic field is weak but extends far...

    August 5, 2013: Something big is about to happen on the sun. According to measurements from NASA-supported observatories, the sun's vast magnetic field is about to flip. "It looks like we're no more than 3 to 4 months away from a complete field reversal," says solar physicist Todd Hoeksema of Stanford University. "This change will have ripple effects throughout the solar system."

    Two EMP experts told Secrets that the EMP flashed through earth's typical orbit around the sun about two weeks before the planet got there. "The world escaped an EMP catastrophe," said Henry Cooper, who lead strategic arms negotiations with the Soviet Union under President Reagan, and who now heads High Frontier, a group pushing for missile defense. "There had been a near-miss about two weeks ago, a Carrington-class coronal mass ejection crossed the orbit of the Earth and basically just missed us," said Peter Vincent Pry, who served on the Congressional EMP Threat Commission from 2001-2008. He was referring to...

    SPACE WEATHER FACT CHECK: Many readers are asking about a report in the Washington Examiner, which states that a Carrington-class solar storm narrowly missed Earth two weeks ago. There was no Carrington-class solar storm two weeks ago. On the contrary, solar activity was low throughout the month of July. The report is erroneous. The possibility of such a storm is, however, worth thinking about: A modern Carrington event would cause significant damage to our high-tech society.

    According to researchers at EMPact America, an organization dedicated to studying and preparing for the possibility of large-scale electro magnetic pulse threats that can destroy our modern day electrical infrastructure, the earth came dangerously close to a serious destabilization event. A couple of weeks ago the sun emitted a massive CME (Coronal Mass Ejection) that, had it been earth-directed, would likely have wiped out critical portions of the world’s power grid and sent developed nations back to the stone age within a matter of seconds. ‘The world escaped an EMP catastrophe,’ Henry Cooper, who now heads High Frontier, a group...
