The 'Perfect Space Storm' Of 1859 129

Posted by timothy from the market-disruption dept.
Polyploid Pimp writes "Bruce Tsurutani of JPL recently published a paper on the 'perfect space storm' of 1859. Apparently, this solar superstorm was so massive that it knocked out telegraphs across the Northern Hemisphere, and the aurora borealis could be seen as far south as Hawaii, Havana, and Rome. Among other interesting notes, the amount of sunlight produced in the region of this solar flare actually doubled! Although the article does not discuss in detail the effects of a solar storm of this size on our current technologies, we can all imagine (maybe something like Escape from L.A.?)"

    Should be interesting to see what happens when the next large barrage of solar winds and large EM fields hit, as everyone may recall a few years ago with one storm a large number of pager satellites and base stations were disrupted, something bigger could certainly bring down large amounts of sattelite based internet infastructure and play havoc with ground based equipment (most notibly WiFi networks.)

    Should we be testing equipment now to minimise the unknown impact of such a natural event?

      They are already planning for it, as it happens, there is a storm occuring at the moment (Classed as a Level 3 out of a scale upto 5).
      The interested parties (ie utility/communications companies) all know about this and are monitoring the situation. They also estimate Aurora to reach very far south in the next couple of weeks. The article is here [startribune.com].

      I suspect there will be a few problems with some older birds and some of the newer ones too that are not well shielded. Less shield = less weight = lower cost to launch, but also shorter lifetime due to increased radiation exposure for the electronics. Some birds are just turned off until the solar event is below critical levels. SEUs (Single Event Upsets, or bit flips) due to EM levels are handled by special circuitry to minimize the loss of data. The excess energy charge on the spacecraft due to the radiation is dumped in many different ways. Purely mechanical systems are not affected by this storm. Most folks don't know but many LEO sattelites go thru a place called the South Atlantic Anomoly where the Earths own Radiation Fields are very intense and systems have to be turned off for several minutes each orbit. But it can be worse, when the earth gets hit with huge amounts of ultraviolet radiation from geomagnetic storms, the upper atmosphere heats up. This heated air rises, and the density of lower satellite orbits (about 1,000 kilometers) increases significantly. This causes drag to increase on satellites; they slow down and gravity pulls them in towards earth. Unless these satellites are boosted into higher orbits, they'll fall and eventually burn up in earth's atmosphere. Remember Skylab? It was a victim of premature entry just because of higher than expected solar activity. This effect can last for several weeks as the earths electrical field is still expanded from the flare. Systems on the ground are also well shielded, since the incident in Quebec in the 1980s where an intense solar storm knocked out the electrical grid! This is NOT to say NOTHING will happen it's just to say it won't be back to the stone ages. Now if we all lived on Mars we'd be hiding in some DEEP hole. Solar flares and how to handle them will be something that needs intense study prior to a Mars mission.
      • This causes drag to increase on satellites; they slow down and gravity pulls them in towards earth.They actually speed up. But they still fall in. Basically, the drag allows them to trade gravitational potential energy for kinetic energy.
        • Nope, grandparent is correct.

          Drag force ALWAYS slows down an object. In this case, it produces a negative acceleration in the tangential direction. Because of its lower velocity, the radius of orbit decreases, and there may be an acceration (smaller than the deceleration in the tangential direction) in the normal direction as a result until the new orbit is reached. Overall, the net speed is decreasing.

          The only reason a satellite will continue falling into the earth is because the air becomes more an
          • Not always, friction is just a means to lose energy. When the energy input for the object is purely kinetic energy, we say the object is slowing down.

            That's not the case for satelites. When satelites are falling, the energy input are BOTH kinetic and gravitational potential (radius decreases, g potential decreases, work done is positive). Since gravitational potential energy is constantly converted into kinetic energy, we're losing both kinds of energy. Whether the satelite is slowing down or not depends o
            • You're forgetting that only a fraction of an orbiting satellite's energy is in the form of gravitational potential energy- most of the energy is in the tangential direction (ie going sideways, across the sky like an airplane). A satellite is "flying" at a speed close to 30 000 km/h when it is in orbit. A huge chunk of this speed must be lost before it can gain a tiny component of speed downwards. kinetic energy in orbiting satellite: = 1/2 *mass * 9.81* ~6 500 000 metres = ~ 30 million * mass of satell

          Not only does solar activity follow an 11 year cycle, it also *appears* to follow an annual cycle, with solar activity (CME's, sunspots) appearing to peak in late October, early November.

          Why is this so odd?

          Because a year on the Sun obviously is not the same as a year on the Earth, and scientist (as of yet) have not been able to pin down why solar activity seems to peak this time of year. At the moment (at least, last time I read up on it, which was during the big Auroral display in November of 2001) scientist were at a loss to explain a 12 month cycle in solar activity.

      When I first read of the telegraphs carching fire I thought BullShit. Afterall the telegraphs were all magneticly driven, low impedance devices--there were no small gaps to arc across or high-impedance low-voltage elements to explode. Moreover the usual situation is that a large loop is relatively hard to induce a lot of current in (transformers try to concentrate flux not spread it out, hence they are made as small as the materials allow).

      but then I started thinking about it more carefully. If one had a magnetic event from the sun then what hit the earth would be an earth-wide, coherent magnetic pulse. In this case the larger the loop of wire the greater the current induced. And telegraphs had miles and miles of wires with macroscopically separated loops. thus the induced current must have been enormormous, hence the fires at the low impedance inductors at the ends.

      On the other hand, the magnetic flux per area might not have been very large. hence modern electronics which are small, and generally have ground or back planes closs to the wires wont receive much induced current.

      in other words the telegraphs were the optimal energy absorbers but modern devices should receive much lower energy coupling.

      • The induced current (and emf) should be proportional to the area. if a telegraph ran, say, 50km and had a 1 meter separation between the poles then the area is 5x10^4 square meters. I would imagine that in order to start a fire the current would need to be perhaps 10 amps sustained or 100 amps pulsed. And lets imagine that the impedance was 100 ohms. so the emf was by these wild guesses in the neigborhood of 1000-10,000 volts. that sort of sounds high but lets assume that's an upper bound.
