Most Powerful Geomagnetic Storm of Solar Cycle 24 Is Happening

astroengine writes: The most powerful solar storm of the current solar cycle is currently reverberating around the globe. Initially triggered by the impact of a coronal mass ejection (CME) hitting our planet's magnetosphere, a relatively mild geomagnetic storm erupted at around 04:30 UT (12:30 a.m. EDT), but it has since ramped-up to an impressive G4-class geomagnetic storm, priming high latitudes for some bright auroral displays.

      Meh, it's already starting to level off. As it turns out, raising and educating kids in a non-agrarian society is really expensive. Plus, when women have career options, most choose not to become baby factories.

      An "agrarian society" generally means at least half the population is engaged in agriculture. By that definition, all first-world nations are most assuredly "technological" or "industrial" as opposed to "agrarian", and have been for quite some time. That's not discounting the importance of agriculture... it's just an acknowledgement of how mechanization and agricultural science allows farmers to be hundreds of times as productive as they used to be.

      Sheesh, this is veering way off-topic.

    wrong. a simple parity check can only correct one bit, most ECC memory is quite capable of multi bit flip correction through interleaving especially with neighbouring bits.

    Parity can not correct any bits. It only detects single bit errors. While many ECC codes exist, the Hamming code overwhelmingly used in computer memories can correct one bit in a 64-bit word and detect two bit errors.

    Actually, memory effects generally come from proton radiation storms, not geomagnetic storms.

    Radiation storms are usually associated with large flares. There need not be an Earth-directed CME, but it does help if a recent event created a stronger magnetic path to Earth. If that was a stream, by the time it gets towards Earth, the end that it's originating from on the sun is near or even beyond the western (rotating away) edge. So most events that cause radiation storms are "near the western limb". (see Parker Spiral)

    Most of the time the atmosphere stops any particles, but when the energy is high there can be secondary collisions. An event much more rare, but usually associated with a radiation storm, is a GLE (ground level enhancement). A spike in high energy radiation level can do strange things. Creating an invisible trail, if a particle goes in the right spot, it can cause some smoke detectors to chirp out of the blue. (Usually just once, less often a few times, not at the lower volume or regular interval of a low-battery warning). Since the radiation bursts are seldom and brief, they don't add up to much exposure on Earth.

    Those with counters may see a slight increase in background on the leading edge CME and fast solar wind. And since fast events clear away some slower but heavier particles that would collide with the atmosphere, there's often a drop to below normal background after an event passes. When CMEs are more frequent, like this last week, an earlier CME sweeping away some solar wind particles leaves a path when a subsequent fast CME won't get slowed down as much as usual. And if there is a fast stream from a coronal hole nearby, we we also have now), it may be sped up and spread out less. There was also a filament eruption. Those usually spread less than flare CMEs, and tend to be denser. I'm not sure what happened with the filament eruption on the 11th. I think it went west-north-west.

    For many people, radon from soil and well water is far more likely to be of concern. Avoid taking long showers during a drought. More ground water is used during droughts, and that's what usually has the most radon.
