Weekend Unthreaded (with 200,000 mile chasm of fire on the sun)

Photograph by NASA/SDO

Read about it, and watch the video below:


As described on the NASA Goddard Youtube channel

Published on Oct 24, 2013

A magnetic filament of solar material erupted on the sun in late September, breaking the quiet conditions in a spectacular fashion. The 200,000 mile long filament ripped through the sun’s atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. Visualizers at NASA’s Goddard Space Flight Center in Greenbelt, Md. combined two days of satellite data to create a short movie of this gigantic event on the sun.

In reality, the sun is not made of fire, but of something called plasma: particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields.

These images were captured on Sept. 29-30, 2013, by NASA’s Solar Dynamics Observatory, or SDO, which constantly observes the sun in a variety of wavelengths.

Different wavelengths help capture different aspect of events in the corona. The red images shown in the movie help highlight plasma at temperatures of 90,000° F and are good for observing filaments as they form and erupt. The yellow images, showing temperatures at 1,000,000° F, are useful for observing material coursing along the sun’s magnetic field lines, seen in the movie as an arcade of loops across the area of the eruption. The browner images at the beginning of the movie show material at temperatures of 1,800,000° F, and it is here where the canyon of fire imagery is most obvious.

By comparing this with the other colors, one sees that the two swirling ribbons moving farther away from each other are, in fact, the footprints of the giant magnetic field loops, which are growing and expanding as the filament pulls them upward.

    Radiation from the sun assumes that a) the Stefan=Boltzmann equation applies b) the sun has a surface c) the surface area is equivalent to the optical projection d) the surface has black body properties e) that the surface temperature is constant f) the sun’s surface temperature (as seen from Earth)using Planck’s Law & Wien’s Displacement law is estimated at about 5760K and g) this later temperature can be used to determine the sun’s heat flux.
    There are a number of papers that indicate that the sun has a core and an atmosphere. The NASA video shows that there is a plasma belt which could confine an atmosphere.
    However, one has to doubt the correctness of any calculation about radiation from the sun. There is no instrument that measures directly the sun’s heat flux. All measurements are indirect making assumptions which are including in an assumed calculation process.
    With probes to and around the sun our knowledge is improving but there is much to learn and we may never have a final answer because of the high temperatures involved.

      Why the time delay in releasing this?

      Is there any reason why the image was acquired on Sept. 29-30, 2013 by the Solar Dynamics Observatory, and yet it gets released a month later.

      NOAA’s Space Weather Prediction Center is also monitoring the situation. The SWPC says there’s no sign of a coronal mass ejection from the latest flare , and that they’re unlikely to cause geomagnetic storm activity that will affect Earthlings?

      Will this one event (sounds huge to me) have any effect on the weather, and I thought we were at maximum of Solar cycle 24 (a very weak one) and is this canyon of fire unusual (or is it a solar flare)?

            I recon the publication delay could have been because Obama closed down everything he could find that would cause the most public pain. But no, we do not yet control the sun. I expect they would like to but they can’t. I could easily applaud the closure of NASA or at least a large part of it, starting with GISS.

      I did not know that. I thought that the figure of 1640W/m2 was a direct measuerement from some sort of radiometer on a satellite.
      The radiation spectrum from the sun does seem to vary somewhat from a perfect black body spectrum.

      Obviously not. The surface isn’t solid. Perhaps you meant “does the sun have heat circulation like the interior of the Earth?”

      There are no solids on the surface so no, at least not like the ones on earth.
      But as the surface surely is affected by the convections of material deeper, then some of the motion of the “stuff” at the surface must be due to those convections. So to that extent there will be at least some similarity to tectonic plates.

    Here is a question……..

    The Pakistani Taliban and the Pakistani government had arranged to conduct peace talks tomorrow in an effort to avoid more civilian bloodshed etc however the peace talks are now cancelled because the US government used a drone to blow up the taliban leader.

    So my question is who wants peace and who does not? Who benefits by endless wars?

      Who benefits by endless wars?

      The military – industrial complex corporations benefit big time supplying armaments, infrastructure, private mercenary armies, fuel, pipelines etc. And then there are profits from valuable natural resources like heroin, oil, gas…and you can install your own friendly leaders into the bargain.

      So who needs peace talks, already?

    Is it too soon for a stocktake on the LNP/Abbott government?

    See, we were told, in uncertain terms, that Tony Abbott becoming PM was a scary proposition and he would make everything awful, the sky would fall, dogs and cats would be living together… etc.

    I haven’t taken much notice of what’s been going on since the election, but from news headlines it does sound like… the troops are being brought home from Afghanistan, at least one Climate QUANGO has been scrapped, and a carbon tax repeal is still brewing.

    The illegal immigrants are being stopped although it’s not clear if Rudd’s “Bali process” agreement with Indonesia deserves more credit than the LNP’s new Navy interception scheme. A policy that went as far as requiring the Navy to intrude into Indonesian waters was hardly a careful plan. I wonder if that was just autocratic myopia or was symptomatic of there being such a groundswell against the LaboGreen symbiosis that the LNP knew they’d get elected even without developing a credible alternative.

    The appointment of Ziggy as the NBNCo CEO so soon after the LNP takeover smells of cronyism and yet I struggle to imagine what actually is going to result from it that will be so bad. It’s probably a case of installing someone who was previously friendly to the Howard government and who can be relied on push the more economical and functional Fibre-to-the-Node + LTE Wireless combo.

    Sure, the LNP acquiesced to the Bank Levy, and that’s wrong, but it’s hard to get too upset about it when its less than a 0.01% tax on accounts.

    Maybe I’m just not fully “ABC-informed” on the issue, but it does seem like… the Abbottcalpyse is proceeding very slowly if it’s even happening at all.

    As for the sun’s eruptions, Piers Corbyn claims to be doing quite nicely at predicting extreme weather in the UK due in part to solar activity.

      .
      This government was never “elected” to deal with any of the issues you have mentioned. Most of them, like “climate change”, and the “boat people” were already passe anyway, regardless of the supposed wailings of Shorten, the ABC, and others.

      This government was elected to:

      1) – Change various Commonwealth laws to allow States’ assets to be privatised sold off to multinationals.
      2) – Change various Commonwealth laws to allow superannuation funds to be invested in siphoned off to multinationals.

      Both objectives are progressing very nicely, thank you.

      Piers Corbyn claims to be doing quite nicely at predicting extreme weather in the UK due in part to solar activity.

      While the UK Met Office is saying here’s what we think its doing just now (after failing to notice the Great Storm of 1987 until it was past) , piers Corbyn is saying :- ‘here’s what I was saying 6 weeks ago, and happening now’..

      The Met Office continues to fudge & hedge, while admitting it is not possible for IT to predict more the 5 days in advance, while claiming the science just doesn’t exist for anyone else to predict it either.

      It has to be said that the Met Office did see this one coming though, from 3 days ahead, and that no doubt did save lives.

      It was to be expected.

      A lot of people have made some very public statements, and reputations are on the line (or so they think). And that is not to mention their investment portfolios.

      They are like a gambler, who wins some, and looses some, and then comes to realise that they are starting to lose more often than they are winning. So they go all in, on one huge bet, in an attempt to recover their losses.

      But the world is moving on. People will watch, see it is entertainment, shrug, ask their friends what they thought the best bits were, and then discuss something else.

      It is a counter-counter revolution that will only resonate with the remaining believers, but will not win back anybody who has realised that the whole thing was a scam.

        Mr. Whakaaro,

        As I watch what’s going on I see the screws being tightened even as the public begins to realize the truth. I wonder which of us will be proved correct. Frankly I hope it’s you. But I have serious doubt at this point.

          Nothing is ever certain, of course.

          But in the intersecting patterns of events, decision makers only ever have a finite set of options. They will make decisions on the basis of least damage, or most benefit. Or they will look for a compromise between the two. The timing of the decision is either made immediately, or is dependent upon the occurrence of other events.

          All of the people involved with this movie have been outspoken in the past, and have publicly taken a position. Hollywood never forgets. And it is the public, that are tightening the screws. So the number of options available for continuing with this scam is diminishing.

          I suggest that this movie will prove to be a compromise between damage limitation, and making a final pass at the box office, to squeeze any remaining revenue out of the system.

            …compromise…

            Compromises with the devil can prove fatal. I would like a clear win-lose endgame where the climate change alarm is buried under the dead weight of its mistaken predictions, faulty science and lies, so deep that no one will ever be able to find it again. These people are not our friends.

            Instead we may end up being the ones grateful to even be alive. I respect your thinking and as I said, I hope you’re right. But they are now at a point where they appear to have no fear of being stopped and talk about their agenda openly. And the number who show some return to sanity is too small and too late. If they become cornered like an animal being stalked almost anything can happen. In the USA, Homeland Security has its private army, complete with tanks. Who do you suppose that army will be used against?

      I could very easily want to shoot every last vestige of climate change believers off into that big solar storm shown in the video at the top of this thread. I think that would teach them to be grateful they live on this planet and should get on with their lives instead of complaining.

      The more their case collapses the louder they get. I fear a revolt of the people eventually that will certainly result in violence on a grand scale. If that’s what it takes then so be it. But I don’t like the prospect in the slightest.

      Good grief. Here we go again.

      It is soo easy to string together every major natural disaster and blame it on something like AGW. And this looks like it’s exactly what they’re doing. It is wrong, dishonest and unethical.

      Maybe we can put together something about the majority of non natural disasters and make a film about that – only it doesn’t get the attention.

    3 Nov: UK Daily Mail: David Rose: Global warming ‘pause’ may last for 20 more years and Arctic sea ice has already started to recover
    Study says warmer temperatures are largely due to natural 300-year cycles
    Actual increase in last 17 years lower than almost every prediction
    Scientists likened continuing pause to a Mexican wave in a stadium
    Even IPCC report co-authors such as Dr Hawkins admit some of the models are ‘too hot’.
    He said: ‘The upper end of the latest climate model projections is inconsistent’ with observed temperatures, though he added even the lower predictions could have ‘negative impacts’ if true.
    But if the pause lasted another ten years, and there were no large volcanic eruptions, ‘then global surface temperatures would be outside the IPCC’s indicative likely range’.
    Professor Curry went much further. ‘The growing divergence between climate model simulations and observations raises the prospect that climate models are inadequate in fundamental ways,’ she said.
    If the pause continued, this would suggest that the models were not ‘fit for purpose’.

    3 Nov: UK Mirror: 340 MPs get their energy bills paid on EXPENSES to heat second homes – with one claiming £5,822
    A Sunday Mirror investigation exposed millionaire Tory who claimed a staggering £5,822 in just 12 months – more than four times the average household energy bill
    By Dominic Herbert, Ben Glaze, Alex Clarke
    Old Etonian Hugo Swire, minister of state for the Foreign Office, claimed a total of £3,198 on gas and oil in 12 months on his second home. Writing in his local paper, the Tory MP for East Devon said: “The reason we are not introducing a price freeze is it simply won’t work. If we want the lights to stay on, consumers and taxpayers are, by some means or other, going to have to pay for it.”
    Conservative MP Tim Yeo, who has temporarily stepped aside as chairman of the Commons Energy and Climate Change Committee, claimed £979.68 on gas and electricity on his London flat. Last year he said an extra £3 a week on fuel bills was a “reasonable price” to pay for green and nuclear power…
    National Pensioners Convention spokesman Neil Duncan-Jordan said the energy claims were “hypocrisy and double standards” from these MPs.
    He said: “Pensioners will be disgusted at how out of touch many MPs are, when many older people will have to choose between heating and eating.”…
    Mr Davey came under fire for suggesting people should wear jumpers to save on bills while Sarah Newton, deputy chairman of the Tory Party, has written an energy-saving guide for constituents telling them to shut their curtains…

    Editor’s note: Climate and energy scientists James Hansen, Ken Caldeira, Kerry Emanuel and Tom Wigley released an open letter Sunday calling on world leaders to support development of safer nuclear power systems. For more on the future of nuclear power as a possible solution for global climate change, watch CNN Films’ presentation of “Pandora’s Promise,” Thursday, November 7, at 9 p.m. ET/PT…

    Cavanagh (Ralph Cavanagh of the Natural Resources Defense Council) said the “movie (Pandora’s Promise) attempts to establish the proposition that mainstream environmentalists are pouring into nuclear advocacy today. They aren’t. I’ve been in the NRDC since 1979. I have a pretty good idea of where the mainstream environmental groups are and have been. I’ve seen no movement.”
    ***Selling nuclear energy to environmentalists is a tough pitch. Hansen acknowledged that many of them won’t easily buy into it. Parts of the community operate like “a religion of sorts, which makes it very difficult,” Hansen said. “They’re not all objectively looking at the pros and cons.”…

    worth reading all:

    4 Nov: Bloomberg: Pankaj Mishra: India Shouldn’t Buy What Japan Is Selling
    An obsession with nuclear power makes many political elites secretive, ruthless and delusional, even as their cherished projects threaten millions of people with disaster. But the egregious examples I have in mind here aren’t Iran, Pakistan and North Korea. They are Japan and India, two countries with democratic institutions.
    Last week in the south Indian city of Pondicherry, I met a friend who had managed to penetrate the security lockdown around Kudankulam, the Russian-built nuclear power station in Tamil Nadu that began partial operations late last month despite strong protests from local villagers.
    Kudankulum lies only a few miles away from a coastline that was ravaged by a tsunami in 2004. Opposition to the plant intensified after another intense earthquake and tsunami in March 2011 caused meltdowns at three nuclear reactors at the Fukushima nuclear plant in Japan. Since then, Indian police have deported the few journalists who have tried to report on the protests, sequestered entire villages and levied criminal charges against tens of thousands of locals, some of whom have been accused of sedition and “waging war on the state.” …
    It is also true that, as Japan scholar Jeff Kingston points out, the export of technology by Japanese companies is key to Abenomics. Japan is at the center of the global nuclear-industrial complex, which stands to benefit greatly from the continued sale of an outdated and demonstrably dangerous technology to wannabe nuclear powers such as India and Turkey.
    Toshiba Corp. owns 87 percent of Westinghouse Electric Co. LLC, which is helping to build a nuclear plant — again, against intense local protests — in the Indian state of Rajasthan; Hitachi Ltd. and Mitsubishi Group are in collaborations with General Electric Co. and the French company Areva SA, whose multiple deals with India make it the real beneficiary of the country’s U.S.-assisted admission to the nuclear club in 2008.
    In this scramble for large profits, democratic values such as oversight, accountability and transparency are likely to be trampled into the dust. The case of Tepco shows how a large and networked company can buy the silence of the media as well as of politicians and regulators. Thus, while Fukushima remains volatile, another nuclear catastrophe seems to be developing in India. As in Japan, the full-throated advocacy of nuclear energy by its leaders, and the absence of debate within the Parliament or the mainstream media, reinforces the bitter truth of a line from Slovenian philosopher Slavoj Zizek that Ramana quotes in his book: “It is indeed true that we live in a society of risky choices, but it is one in which only some do the choosing, while others do the risking.”
    (Pankaj Mishra is the author of “From the Ruins of Empire: The Revolt Against the West and the Remaking of Asia” and a Bloomberg View columnist.)
