2011 Solar Flare

2011 Solar Flare2011 Solar Flare, Sky watchers in the northern U.S. tonight can be the main beneficiaries of the sun belching took place June 7. While the storm included a solar flare, the giant pulse plasma, electricity, and the stuff that springs across nearly half the sun’s surface was a coronal mass ejection – and that is what we can thank filling the dawn sky Wednesday night. If you approach the hordes of charged particles that reach Earth event at the right time, the aurora may be visible on the northern horizon to the south of Washington, DC, according to a warning today from the University of Alaska, the Geophysical Institute. Given the intensity of the explosion, “it is reasonable to expect that [conditions] to bring the dawn of Milwaukee, and visible on the horizon north along a line from Portland, Oregon, southern Nebraska, southern Illinois, Washington, DC, “say the aurora forecasters. Weather permitting, of course.

If you live in the northern half of the country, look north at about midnight local time, according to experts. Keep checking their website, also for ongoing updates on viewing conditions.

Residents in the southern hemisphere are the mirrors opposite of any aurora in the northern hemisphere.

The solar flare, which peaked at 1:41 am Eastern Time on Tuesday, was dramatically captured by the Solar Dynamics Observatory of NASA. The spacecraft was launched in February 2010 on a five-year mission to observe the Sun and its effects on space weather around Earth.

Tuesday’s activity in the sun includes a solar flare and storm of a minor radiation, according to researchers at the Goddard Space Flight Center in Greenbelt, Maryland

But the case was amazing coronal mass ejection – a huge release of energy that sends billions of tons of matter, largely in the form of protons and electrons, all velocity of the star at speeds measured in million kilometers per hour.

If the region in the sun, stretching from the explosion is directed towards Earth, the ejected particles slam into the Earth’s magnetic field when they arrive. The collision in effect compresses the magnetic field on the dayside of the planet. Also included is the energy field that extends into the night side into a comet-like tail – longer than Earth hosts modest queue during times of solar quiet.

The movement of these expelled, charged particles also represents an electric current – which means that carries its own magnetic fields.

When these fields and currents interact with the Earth’s magnetic field at ground level, which can induce electrical currents in unusually large pipelines and long distance services of energy. This can increase corrosion in pipes and potentially parts of network overload.

In effect, these important pieces of infrastructure “antennas detects changes in the Earth’s magnetic field,” says Antti Pulkkinen, a physicist at Goddard who is involved in modeling the interaction between the sun and the upper atmosphere Earth.

Meanwhile, above the planet’s surface, compression of the Earth’s magnetic field and solar Smackdown has other effects.

Spacecraft in geostationary orbit, often protected by the magnetic field suddenly is exposed to higher, potentially harmful levels of cosmic radiation. Also be vulnerable to the accumulation of electrical charges on their surface, which can suddenly stop downloading and sensitive electronics.

And on the night side of Earth, the magnetic field can be stretched only so far. When you cannot take more energy than solar particle mass step, the field is extended snap back into what researchers call “magnetic reconnection.”

This movement-accelerated charged particles that are already in the magnetic field, as well as others in the CME has donated back to Earth. These particles travel along magnetic field lines, the plow in the upper atmosphere in Earth’s geomagnetic poles.

The electrons collide in this subatomic home race with the atoms of hydrogen, oxygen and nitrogen in the upper atmosphere, causing it to fluoresce in the familiar red, blue and green lights on the north and south.
