At left, an all-sky image of red light taken from Italy in 2011. To the north appears the diffuse aurora just above the horizon,
with a red arc above it. At right, the northern portion of the image.
When streams of high-energy, charged particles come rushing from the sun to batter Earth, they cause what are called geomagnetic storms. These events are disruptions in the magnetosphere, the part of Earth’s atmosphere dominated by the planet’s magnetic field. The most dramatic effects of these storms are giant, bright auroras in Earth’s polar regions, but the tempests result in other striking consequences as well, such as faintly glowing red arcs high up in the ionosphere. This is the electrically charged part of Earth’s atmosphere, stretching from about 50 to 370 miles (85 to 600 kilometers) above the Earth.
This is interesting to note as it comes at the same time there is shifting of our magnetospshere, increased earthquakes, photon belt, unusual weather, sinkholes, mysterious earth noises and yes, high sun activity.
What does it mean? We are finding out, it all seems to be related… keep watch for new trends in everything, as our earth lives shift into higher frequencies.
