    Interesting phil. I just got home from my disney vacation and had regular intermittent GPS signal loss during the trip. I would like to blame it on the rental car(had GPS also)which I thought might be interupting the signal.

      Space weather expert has ominous forecast

      Mike Hapgood, who studies solar events, says the world isn't prepared for a truly damaging storm. And one could happen soon.

        Past "weather event"? Perhaps ...

        Mysterious radiation burst recorded in tree rings


        Spike in carbon-14 levels indicates a massive cosmic event — but supernovae and solar flares ruled out.

        EXCERPTS:

        Just over 1,200 years ago, the planet was hit by an extremely intense burst of high-energy radiation of unknown cause, scientists studying tree-ring data have found.
        The radiation burst, which seems to have hit between ad 774 and ad 775, was detected by looking at the amounts of the radioactive isotope carbon-14 in tree rings that formed during the ad 775 growing season in the Northern Hemisphere. The increase in 14C levels is so clear that the scientists, led by Fusa Miyake, a cosmic-ray physicist from Nagoya University in Japan, concludethat the atmospheric level of 14C must have jumped by 1.2% over the course of no longer than a year, about 20 times more than the normal rate of variation. Their study is published online in Nature today1.
        ........
        Cosmic puzzle

        The only known events that can produce a 14C spike are floods of γ-rays from supernova explosions or proton storms from giant solar flares. But neither seems likely, Miyake says, because each should have been large enough to have had other effects that would have been observed at the time.
        ...........


        Baker, however, thinks that Miyake's team may have been too quick to rule out a solar flare. Flares are sometimes associated with coronal mass ejections (CMEs) — huge eruptions of magnetically charged plasma from the Sun's atmosphere that send streams of charged particles towards Earth. It might be possible, he says, for CMEs to be accompanied by conditions in which an unusual number of protons are accelerated to super-high energies, even without the flare itself being "ridiculously strong".
        "We know much more these days about how important proton acceleration is at the shock fronts that precede CME structures as they propagate towards Earth," Baker says. "I would like to think about whether a strong CME moving directly towards Earth could have produced the intense proton population that impacted Earth's atmosphere."

        I'm going with an exceptional CME, and if it happened once, could happen again ....

          Solar fireworks might be heading our way for the 4th


          The sun sent out a flare powerful enough to disrupt radio communications over Europe today, along with an eruption of electrically charged particles that just might sweep past Earth's magnetic field in time to spark a Fourth of July show of auroral fireworks.
          The M5.6-class solar flare, observed by NASA's Solar Dynamic Observatory at 6:52 a.m. ET (10:52 GMT), was almost powerful enough to cross over from the medium M-class category to an extreme X-class event, SpaceWeather.com's Tony Phillips noted. "A pulse of X-rays and UV radiation from the flare illuminated Earth's upper atmosphere, producing waves of ionization over Europe," he wrote.

            Solar flares keep on getting stronger - with latest hotspot the size of 15 Earths strung together

            ....
            Solar activity runs in 11-year cycles, with the current one peaking in 2013, so more violent space weather is on the horizon.

            Dr Matthew Penn, of the National Solar Observatory in Arizona, said recently: 'Because the sun is becoming more active, it will have an impact on millions of people. Sunspots can cause the biggest and most damaging space storms that occur.
            'During the next two years, we are expecting the number of sunspots visible on the sun to reach a maximum. We know that sunspots are the source of a lot of space weather and solar storms, so we expect a larger number of solar storms here at the Earth.’

            Some good general information on sunspots and flares here for those wanting a reference, etc.

              UPDATE, 3:30 p.m.: NOAA’s Space Weather Prediction Center (SWPC) just posted the following:
              The R3 (Strong) Radio Blackout today at 12:49 EDT (1649 UTC) was accompanied by an earth-directed CME. Hampered by limited observations of the event, SWPC forecasters are now anticipating the passage of the [coronal mass ejection] around 1:00 a.m. EDT, Saturday, July 14. G1 (minor) Geomagnetic Storm activity is expected to then ensue through the rest of the day.
              In short, NOAA is predicting minor effects from this space weather event - no major impacts on the power grid or satellites anticipated - although we remind you forecasting space weather is difficult and surprises are possible. Sky watchers in northern U.S. (and high latitudes) may have an opportunity to see aurora late Friday night into early Saturday morning.

                Great.
                Friday the 13th and here come the solar storms...

                and now I hear that a couple of comets are dropping into the sun this weekend. Normally that would not amount to anything, but with the storm situation, is this anything?

                  Just cosmic coincidence!

                  Like all that 'Earthly Global Cooling and Warming' before Humans got 'Industrial Age and SUVs'; nothing to be concerned with; "nothing to see here folks, move along ..."

                        Got to see the Northern lights right here in the sky over Colorado last night.

                        Telephones, televisions, computers and satellite dishes continue to work normally.


                        So much for the science of Chicken Little.

                            I really like Dr. Schoch, he's one of the reasons I'm going back to school for Geology. An interesting theory he has going there.
