    ...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...

    Scientists with the National Oceanic and Atmospheric Administration say an “extreme” solar flare has been detected and while Earth appears to be in the bull’s-eye, exactly which part of the planet will see the biggest impact isn’t yet known. Such phenomenon can disrupt power grids, radio transmissions and other electronics, and in a worst-case scenario could actually take such systems down, perhaps for extended periods. Officials with the federal agency said the flare is near the center of the sun and happened at 1:45 EDT Wednesday.

    A similar process is playing out with the probe's speed: At the peak of its first two perihelions, the spacecraft traveled at about 213,200 mph (343,000 km/h), also breaking records, but future close approaches will see the Parker Solar Probe moving still faster. These close grazes are anxious times for scientists and engineers on the mission because the spacecraft is out of communication with Earth for several days before and after each perihelion. The radio silence is designed to let the spacecraft focus on keeping its instruments tucked safely behind the thick shield that protects them from the incredible heat...

    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...

    In November 2016, astronomers watched a young star some 1,500 light-years away from Earth belch out an explosion of plasma and radiation that was roughly 10 billion times more powerful than any flare ever seen leaving Earth's sun. This sudden stellar eruption may be the most luminous known flare ever released by a young star — and it could help scientists better understand the still-murky process of star formation. "Observing flares around the youngest stars is new territory and it is giving us key insights into the physical conditions of these systems," Steve Mairs, an astronomer and lead author of the study, said...

    In our last post, we looked at seasonal forecasts that have long been calling for a cold late winter in the central and eastern United States based on various signals, including stratospheric warming and the El Niño/Southern Oscillation. A winter storm dubbed Harper is the first salvo in this transition. This weekend, Harper will bring very heavy snows and widespread ice across large parts of the Northeast. See weather.com for frequent updates on Harper. There’s another player in the seasonal prediction game, and it’s one that many forecasters have long derided or dismissed: the 11-year cycle of solar activity. In...

  • Coronal hole faces Earth

    09/05/2018 7:12:36 AM PDT · by BenLurkin · 41 replies
    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.

    Tiny gap between private trade confirmations and public data feed can be exploited to detect market moves, critics say Five years ago, the world’s largest exchange operator vowed to fix a flaw in its systems that allowed high-speed traders to infer the direction of the futures market a fraction of a second before everyone else. Now, the defect is back at CME Group Inc.,traders say. And some allege it is yielding rich profits for ultrafast firms at the expense of ordinary investors. The problem arises from the two ways that CME distributes information about a trade. One is the private...

    Just had the largest X-ray Flare in history while the biggest Hurricane in history is in the Atlantic. CME from previous X-5 Flare is going to hit Earth tonight around 5-6 PM EDT. The initial estimate of the arrival of the X-10 Flare is 6-7 AM EDT on 8 September 2017. This could be a repeat of the 1859 Carrington Event. We could be doing Irma without electronics or electricity.

Lots of eyebrows were raised when a securities trader with no background in any of this was introduced as a new...
  • Solar storm of August 28 to September 2, 1859

    Wikipedia ^ | Wikipedia
    The Solar storm of August 28 to September 2, 1859—known as the Carrington Event—was a powerful geomagnetic solar storm during solar cycle 10 (1855–1867). A solar coronal mass ejection(CME) hit Earth's magnetosphere and induced one of the largest geomagnetic storms on record. The flare traveled directly toward Earth, taking 17.6 hours to make the 150 million kilometer (93 million mile) journey. It is believed that the relatively high speed of this CME (typical CMEs take several days to arrive at Earth) was made possible by a prior CME, perhaps the cause of the large aurora event on August 29, that...

    It is an accepted fact that Coronal Mass Ejection events mess with the power grid and communications. What is not so accepted is the growing pattern of severity of CME's as a result of both solar perturbations, AND a shifting of the Earth's magnetic poles plus their weakening at an accelerating rate. This issue is orders of magnitudes more important than anthropogenic global warming and could easily erase the latter as a concern for anyone but the hypnotized.

    NASA ^ | Wednesday, April 06, 2016 | (see photo credit)
    Explanation: Jupiter has auroras. Like near the Earth, the magnetic field of our Solar System's largest planet compresses when impacted by a gust of charged particles from the Sun. This magnetic compression funnels charged particles towards Jupiter's poles and down into the atmosphere. There, electrons are temporarily excited or knocked away from atmospheric gases, after which, when de-exciting or recombining with atmospheric ions, auroral light is emitted. The featured illustration portrays the magnificent magnetosphere around Jupiter in action. In the inset image released last month, the Earth-orbiting Chandra X-ray Observatory shows unexpectedly powerful X-ray light emitted by Jovian auroras, depicted...

    Three coronal holes spread across the sun are pointing at Earth. As a result, the US Space Weather Prediction Centre in Boulder, Colorado, and the Space Weather Operations Centre of the UK Met Office in Exeter have issued an alert for tomorrow of a minor geomagnetic storm. “Early on Day 3 (April 2), a high-speed stream from coronal hole 67 is expected to reach Earth,” said the Met Office. Forecasters in the US and UK predict this could confuse migrating birds and other animals, cause minor problems with satellites and make an aurora visible as far south as Maine and...

    Science Daily ^ | 3/24/16 | Christoffer Karoff, et al
    Earth is often struck by solar eruptions. These eruptions consist of energetic particles that are hurled away from the Sun into space, where those directed towards Earth encounter the magnetic field around our planet. When these eruptions interact with Earth's magnetic field they cause beautiful auroras. A poetic phenomenon that reminds us, that our closest star is an unpredictable neighbor. When the Sun pours out gigantic amounts of hot plasma during the large solar eruptions, it may have severe consequences on Earth. Solar eruptions are, however, nothing compared to the eruption we see on other stars, the so-called 'superflares'. Superflares...
