Two Huge Holes In the Sun Spotted 204

Posted by timothy from the need-that-like-a-hole-the-sun dept.
An anonymous reader writes "Japanese scientists have spotted two huge holes on the sun's magnetic field, and it appears there is some reason to be concerned about. The holes, called coronal holes, are gateways for solar material and gas to spill out into space, according to space.com. The gaps in the sun's magnetic field make a hole through its atmosphere, letting gas out, NASA has said."

      Well, I've been a ham radio operator for a long time, and have seen this sort of thing occasionally.

      No, it won't directly harm us, but it could wreak havoc on the radio spectrum.

      Depending on what exactly happens, we hams may see some terrific "skip" conditions on the shortwave
      bands, or we may experience a near-complete wipe-out where nothing gets through, let alone bouncing
      off a layer in the upper atmosphere. It may also disrupt some satellite links depending on the position of
      the various satellites relative to the wave of incoming particles/stuff and which way the satellites are aimed
      towards their ground stations.

      Folks in higher latitudes may be treated to an incredible display of "Northern Lights" or "Southern Lights" as appropriate.
      Considering we're just now coming out of a minimum in the 11 year sunspot cycle, this is indeed an interesting event.

      Having done a little scanning of this news from the source of the article, NASA, Space Weather, this is hardly rare and not the sign of an impending stellar apocalypse.

    The way I see it, unless one of those holes were pointed straight at us for an extended time, which is impossible due to difference in the orbital velocity of Earth and the rotational velocity of the Sun, we have nothing to worry about, and even then we'd only get a few blanked-out satellites.

    • The concern is coming from an anonymous International Business Times writer, who linked to the actual NASA release and said "OH NOES", then speculated that maybe the sun is just getting tired from working all the time. That is to say, somebody who knows nothing about the particular field he's "reporting" on is worried, and for no reason whatsoever.
    • While I agree with you that it's extremely unlikely that a flare from either of these would hit us, I disagree with you on how serious it would be if they did. Relatively minor flares knock out satellites. Larger ones could easily cause a major extinction event. We have no scientific data regarding how often flares that larger happen, or how often they hit earth. But it is certainly within the realm of feasibility that one could be a very real problem for us in the future.

    Visit spaceweather.com daily for a month or two, and keep an eye on the various Sun images on the left side. One is used to point out coronal holes, and you'll quickly realize how common they are. This may be related to the approaching solar maximum, though don't quote me on that.

    I'm much more concerned about flare and mass ejection frequency. With all the satellites and poorly-shielded electrical circuits we rely upon, one or two wicked ejections aimed at Earth could turn a lot of gear into expensive junk.

      Using that number along with the estimated mass of the Earth at 6E+24 kg, it takes the sun 307000 years to burn off one Terra. The estimate for number of Earths that could fit into the sun is 1.3 million (volume, not mass) so it would take 399 Billion years for the sun to burn off an equivalent volume of Earths assuming a similar mass/density.
