    Huge Solar Storm coming!!

    Largest in 5 years!!

    A strong geomagnetic storm is racing from the Sun toward Earth, and its expected arrival on Thursday could affect power grids, airplane routes and space-based satellite navigation systems, U.S. space weather experts said.

    The storm, a big cloud of charged particles flung from the Sun at about 4.5 million miles per hour (7.2 million km per hour), was spawned by a pair of solar flares, scientists said.

    This is probably the strongest such event in nearly six years, and is likely more intense than a similar storm in late January, said Joseph Kunches, a space weather specialist at the U.S. National Oceanic and Atmospheric Administration NOAA.L.

    This solar disturbance is a three-stage affair, or as Kunches said in a telephone interview from Boulder, Colorado: "We hit the trifecta."

    These are the stages he described, with the first two already affecting Earth:

    * First, two solar flares moving at nearly the speed of light reached Earth late on Tuesday. Such flares can cause radio blackouts.

    * Then, solar radiation hit Earth's magnetic field on Wednesday, with possible impact on air traffic, especially near the poles, satellites and any astronauts taking space walks. This phase could last for days.

    * Finally, the plasma cloud sent by the coronal mass ejection, which is basically a big chunk of the Sun's atmosphere, is expected to arrive at Earth early on Thursday.

    This phase can disrupt power grids, satellites, oil pipelines and high-accuracy GPS systems used by oil drillers, surveyors and some agricultural operations, scientists said.

    GPS systems used for less-refined functions, such as the turn-by-turn navigation found in many cars, should not be affected, according to NOAA's Doug Biesiecker.

    Kunches said the geomagnetic component of the storm may arrive a bit ahead of schedule because it follows a previous storm that left the Sun on Sunday and is currently buffeting the Earth's magnetosphere.

    "When you've already had one coronal mass ejection storm, sometimes the next coronal mass ejection storm is faster to get here," Kunches said.

    These storms could produce some vivid auroras, according to experts. In the Northern Hemisphere, the aurora borealis could be visible at mid-latitudes, which in the United States could include New York, Illinois and Iowa.

    Such stormy space weather is unusual in recent history, according to Harlan Spence, an astrophysicist at the University of New Hampshire who is principal investigator on the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) aboardNASA's Lunar Reconnaissance Orbiter.

    "These relatively large (solar) events, which we've had maybe a couple of handfuls total in the course of a decade, we've now had two or three of them, more or less right on top of each other," Spence said by telephone.

    The Sun is on the ascendant phase of its 11-year cycle of solar activity, with the peak expected next year, scientists said.

    "It's a clear harbinger that the Sun is waking up," Spence said. "We're trying to put this in context not only ... of what has the Sun done in the past, but what is the biggest thing the Sun is capable of and what should we be planning for in terms of extreme sorts of events in the future."

    It’s been a dream of mine for a long time to see the aurora borealis. I want to get a strong telescope with a good filter so I can look at the sun.

    So far it's been tame according to this article.

    Solar storms from Tuesday night's powerful flare on the surface of the sun seemed to be less than anticipated and fizzling away. But Friday morning brought new surprises.

    Geomagnetic storms have picked up, says NASA's Alex Young, and a new solar flare occurred about 7:30 p.m. PST on Thursday.

    "Earth's magnetosphere continues its upset state," Young, a solar physicist with the Goddard Space Flight Center, says on his website, the Sun Today. The "kp index," which measures just how disturbed the magnetic field is, took a bit of a roller-coaster ride, from a level 5 to 4 and then zooming up to 7.

    The flare, Young says on his site, produced some temporary radio blackouts, and there could be more activity from the sunspot group where the flare originated.

    At the current kp index level, according to the National Oceanic and Atmospheric Administration, high-frequency radio -- and thus some airline routes -- as well as power systems could be affected.

    Solar storms this strong also could wreak havoc with satellite navigation and spacecraft components.

    Meanwhile, those in northern climes were expecting some terrific auroras in Friday's early morning hours. Auroras were possible as far south in the U.S. as Illinois and Oregon, NOAA said.,4648509.story

    I went out on the back deck to smoke at about 2:30am, it was in the winter of 2007 in Michigan...I looked up and saw the most amazing shy ever, it was the Aurora Borealis! Next to watching my children being born it was the most awesome thing I had ever seen. If you have a chance to see it, stay up all night and wait for it, unforgettable!
