    Abstract:Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019–2055) to a Modern grand minimum similar to Maunder one. On the other hand, a reconstruction of solar total irradiance suggests that since the Maunder minimum there is an increase in the cycle-averaged total solar irradiance (TSI) by a value of about 1–1.5 Wm−2 closely correlated with an increase of the baseline (average) terrestrial temperature. In order to understand these two opposite trends, we...

    Phys dot org ^ | June 2019 | James Lynch, University of Michigan
    ...why is its outer atmosphere hotter than its fiery surface? University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA's Parker Solar Probe. In roughly two years, the probe will be the first manmade craft to enter the zone surrounding the sun where heating looks fundamentally different than what has previously been seen in space. This will allow them to test their theory that the heating is due to small magnetic waves travelling back and forth within the zone... Such high temperatures cause the solar atmosphere to swell to many times the...
  • The sun has ‘reached solar minimum’ and its surface is ominously calm

    Eruptions from the face of our star are called ‘prominences’ and cause vast amounts of superhot gas to shoot into space, often forming beautiful loops on the solar surface. During the solar minimum, the number of flares and sunspots is dramatically reduced. When the sun leaps back from its minimum after roughly 11 years, we’re likely to see more and more ferocious explosions on the sun. Nasa warned: ‘After our Sun passes the current Solar Minimum, solar activity like eruptive prominences are expected to become more common over the next few years.’ The space agency has just released dramatic pictures...

    An intense blast of high-energy protons from the Sun pummelled the Earth in about 660 BC and left a distinct record of cosmogenic nuclei in the Greenland ice sheet. The discovery was made by an international team of scientists who say the event was one most powerful solar storms known to have struck Earth. The team calculates that the storm was about ten times more intense than any event that has occurred in the past 70 years. “If that solar storm had occurred today, it could have had severe effects on our hi-tech society”, says Raimund Muscheler of Sweden’s University...

    Forbes ^ | 1/3/19 | Ethan Siegel
    On January 3rd, 2019, Earth reached the point in its orbit where it's at its closest approach to the Sun: perihelion. Every object orbiting a single mass (like our Sun) makes an ellipse, containing a point of closest approach that's unique to that particular orbit, known as periapsis. For the past 4.5 billion years, Earth has orbited the Sun in an ellipse, just like all the other planets orbiting their stars in all the other mature solar systems throughout the galaxy and Universe. But there's something you may not expect or appreciate that nevertheless occurs: Earth's orbital path doesn't remain...

    A leading pioneer in the study of Grand Solar Minima and their effects on the planet has been solar physicist Professor Valentina Zharkova of Northumbria University. She has been attacked savagely for her theory that the weakened solar magnetosphere during a Grand Solar Minimum is the main factor in driving global cooling on Earth, but she is increasingly being vindicated as global cooling progresses. Recently, Professor Zharkova gave a lecture to the Global Warming Policy Foundation. You can view the lecture below, but it’s heavy-going. Here’s a summary of her main points: • The solar magnetosphere is key to understanding...

    “It could happen in a matter of months,” says Martin Mlynczak of NASA’s Langley Research Center. ________________ “The sun is entering one of the deepest Solar Minima of the Space Age,” wrote Dr Tony Phillips just six weeks ago, on 27 Sep 2018. Sunspots have been absent for most of 2018 and Earth’s upper atmosphere is responding, says Phillips, editor of spaceweather.com. Data from NASA’s TIMED satellite show that the thermosphere (the uppermost layer of air around our planet) is cooling and shrinking, literally decreasing the radius of the atmosphere. To help track the latest developments, Martin Mlynczak of NASA’s...

    Many scientists firmly believe that our universe and Solar System are billions of years old. However, massive data recorded by 50 years' worth of unmanned probes traversing space shows without a doubt that the planets with their moons and comets are actually very young. Our sun powers through its nuclear fuel, and as such it slowly changes constitution. Famed solar astronomer John A. Eddy was quoted, and others in his field believe billions of years ago the sun was dimmer and thus the Earth became a frozen ball. But Mr. Eddy has also recognized that all our information about the...
  • Coronal hole faces Earth

    After last month's impressive G3 geomagnetic storm caused by a coronal mass ejection, it is time to welcome back a familiar solar feature on our nearest star today. We have a small coronal hole facing our planet today. The high speed solar wind stream flowing from this coronal hole will likely take about three days to arrive at Earth which means the solar wind stream should impact Earth somewhere this Friday, 7 September. Active geomagnetic conditions are likely which is great news for northern hemisphere high latitude sky watchers who finally enjoy proper dark nights again.

    It is a slam-dunk certainty that American mainstream media will seize upon a recent story in the Los Angeles Times, “Southern California sets all-time heat records amid broiling conditions,” as justification for its continuing support of the contested theory of man-caused global warming. It has already happened with a Yahoo News story claiming that the new temperature records world-wide prove man causes climate change.But there are problems in pursuing that path.First, days that reach and exceed 117-degree temperatures have been known to happen for a very long time in the interior basin of southern California, sometimes referred to as “Death...

    Have you been keeping an eye on Sol lately? One of the top astronomy stories for 2018 may be what’s not happening, and how inactive our host star has become. The strange tale of Solar Cycle #24 is ending with an expected whimper: as of May 8th, the Earthward face of the Sun had been spotless for 73 out of 128 days thus far for 2018, or more than 57% of the time. This wasn’t entirely unexpected, as the solar minimum between solar cycle #23 and #24 saw 260 spotless days in 2009 – the most recorded in a single...

    "Solar Rossby waves are gigantic in size, with wavelengths comparable to the solar radius," study co-author Laurent Gizon, of the Max Planck Institute for Solar System Research, said in a statement. (The average radius of the sun is a whopping 432,450 miles, or 696,000 kilometers.) Even so, these waves move very slowly, with shallow troughs and peaks, so they aren't always easy to detect, especially amid the other swirls and disturbances on a body as lively as the sun. … Researchers from the Max Planck Institute for Solar System Research, the University of Göttingen (both in Germany), New York University...

This sunspot with an opposite polarity, which decayed so quickly that it did not rate getting a sunspot number, was not the first... The grand minimum of the 1600s, dubbed the Maunder Minimum in honor of the scientist who first identified it, was a century where almost no sunspots were visible. There was no apparent solar cycle....

    A massive "hole" on the surface of the sun has unleashed a strong solar wind that scientists say may amp up the northern lights in some areas of the U.S. and could disrupt satellite communications over the next few days. Data from NASA's Solar Dynamics Observatory revealed a vast region where the sun's magnetic field has opened up, creating a gap in the sun's outer atmosphere, called the corona. This region, also known as a coronal hole, allows charged particles to escape and flow toward Earth in an increased solar wind. As a result, the U.S. Space Weather Prediction Center...

    It’s what scientists have termed a ‘grand minimum’ — a particularly low point in what is otherwise a steady 11-year cycle. Over this cycle, the Sun’s tumultuous heart races and rests. At its high point, the nuclear fusion at the Sun’s core forces more magnetic loops high into its boiling atmosphere — ejecting more ultraviolet radiation and generating sunspots and flares. When it’s quiet, the Sun’s surface goes calm. It ejects less ultraviolet radiation. Now scientists have scoured the skies and history for evidence of an even greater cycle amid these cycles. It’s what scientists have termed a ‘grand minimum’...
