NASA Warns of Magnetic Storm After Huge Solar Flare

coondoggie writes "NASA today said a strong-to-severe geomagnetic storm is in progress following a massive solar flare and coronal mass ejection (CME). CMEs are a solar phenomenon that can send solar particles into space and affect electronic systems in satellites and on Earth. Simulations indicate that solar wind plasma has penetrated close to geosynchronous orbit starting at 9am today. Geosynchronous satellites could therefore be directly exposed to solar wind plasma and magnetic fields. High-latitude sky watchers should be alert for auroras after nightfall, NASA stated."

      While Slashdot is late to the party here Spaceweather does say that people near the poles should still keep an eye out.

      So the story essentially becomes: "If you're in Alaska, Northern Europe or somewhere similar there is a greater than usual chance of auroras today."

      In the southern hemisphere only Antarctica is south enough and the people there probably don't need outside help in spotting auroras. =)

      Well, that is part of my question around superluminal neutrinos. If they really worked that way, then couldn't you potentially detect a supernova weeks or months before it becomes visible via light/radio? The speed difference is small, but when the travel time is measured in decades to centuries a tiny percentage adds up.

      Except that they don't, in fact, observe neutrinos before supernovae. They arrive right when they "should", at or slightly after the light arrives. Bear in mind that \Delta t is 6x10^{-8} seconds over 500 miles. A light year is roughly 6 x 10^12 miles, so a supernova from hundreds to millions of LY away would produce neutrinos that arrive anywhere from hours to days or months before the light. And they don't, or at least no one has yet observed that they do. That is, it isn't really a tiny percentage, not tiny as in at all difficult to resolve. 60 nanoseconds is hundreds of CPU clock cycles -- your computer could resolve the timing to a couple of significant figures and I'm guessing state of the art clocks and transducers can do at least orders of magnitude better.

      It's one of several reasons that people are skeptical about the superluminal result, one of several things that will ultimately have to be explained if the superluminal result is eventually validated.

      The only supernova where neutrinos could be assigned to was 1987A, and the number counts (detailed on Wikipedia) were too low to state anything significant. However, there was a increase in neutrino counts 3 hours before the light arrived.

      You also have to keep in mind that process producing the neutrinos in a SN could just be earlier. Yes, neutrino speed should be verified.
