Massive solar flares could bring down the national electrical grid and affect power in the U.S. “for a period of years,” according to a 2009 NASA report. On March 27th Jack Jobe, Emmy-nominated journalist and survival teacher, shows how to prepare yourself and your family on National Geographic´s “Doomsday Preppers.” Aurora, Colorado (PRWEB) March 24, 2012 National Geographic takes viewers inside the world of Jack Jobe, a “Common Sense Survival...

Solar Storm Threat Appears To Have Passed
2012-03-09 12:26:43

[ Watch the Solar Flare in Action Here and Here ] Two recent Coronal Mass Ejections (CMEs) -- massive bursts of solar wind produced by the Sun -- appear to have caused little or no damage to electrical systems, according to scientists. The CMEs were caught by NASA as they took off from the Sun, traveling faster than 1,300 miles per second. The first wave hit yesterday morning, March 8. The second hit late last night into early this morning. Joseph Kunches, a scientist with the...

CMEs Heading Towards Earth

[ Watch the Solar Flare in Action Here and Here ] NASA said on Wednesday that two Coronal Mass Ejections (CMEs) are now traveling faster than 1,300 miles per second, on track towards Earth. NASA's Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) caught the CMEs as they took-off from the sun. The space agency said the first CME, which is traveling at about 1,300 miles per second, will reach Earth on the morning of March 8. This CME...

Flying Through A Geomagnetic Storm

[ Watch the Video ] Glowing green and red, shimmering hypnotically across the night sky, the aurora borealis is a wonder to behold.  Longtime sky watchers say it is the greatest show on Earth. It might be the greatest show in Earth orbit, too. High above our planet, astronauts onboard the International Space Station (ISS) have been enjoying an up-close view of auroras outside their windows as the ISS flies through geomagnetic storms. “We can actually fly into the...

RHESSI Mission Celebrates Ten Years And Forty Thousand X-Ray Flares

[ Watch the Video ] On February 5, 2002, NASA launched what was then called the High Energy Solar Spectroscopic Imager (HESSI) into orbit. Renamed within months as the Ramaty High Energy Solar Spectroscopic Imager (RHESSI) after Reuven Ramaty, a deceased NASA scientist who had long championed the mission, the spacecraft's job was to observe giant explosions on the sun called solar flares. During a solar flare, the gas soars to over 20 million degrees Fahrenheit, and emits X-rays that...

Sun Delivered Curveball Of Powerful Radiation At Earth

A potent follow-up solar flare, which occurred Friday (Jan. 27, 2012), just days after the Sun launched the biggest coronal mass ejection (CME) seen in nearly a decade, delivered a powerful radiation punch to Earth's magnetic field despite the fact that it was aimed away from our planet. According to University of New Hampshire scientists currently studying and modeling various aspects of solar radiation, this was due to both the existing population of energetic particles launched by the...

NASA Captures Another Massive Solar Flare On January 27: Video
2012-01-30 10:35:37

[ Watch the Video ] The sun unleashed an X1.8 class flare that began at 1:12 PM ET on January 27, 2012 and peaked at 1:37. The flare immediately caused a strong radio blackout at low-latitudes, which was rated an R3 on NOAA's scale from R1-5. The blackout soon subsided to a minor R1 storm. Models from NASA's Goddard Space Weather Center predict that the CME is traveling at over 1500 miles per second. It does not initially appear to be Earth-directed, but Earth may get a glancing blow....

The geographical sciences website EurekaMag.com publishes insights into specific subjects of all areas of geographical science. The latest review covers Aurora borealis which are the Northern Lights caused by radiation emitted as light from atoms in the upper atmosphere as they are hit by fast-moving electrons and protons. Two other newly published reviews cover Solar Flare which is a large energy release at the sun's surface, and Solar Storm which is a massive burst of solar wind associated...

Improved Forecasting to Coincide with Peak in Solar Activity After years of relative somnolence, the sun is beginning to stir. By the time it's fully awake in about 20 months, the team at NASA´s Goddard Space Flight Center in Greenbelt, Md., charged with researching and tracking solar activity, will have at their dispoal a greatly enhanced forecasting capability. Goddard's Space Weather Laboratory recently received support under NASA's Space Technology Program Game Changing Program...

Solar Flare Collides With Earth Causing Disruptions
2012-01-25 10:51:51

[ Watch the Video ] A solar flare from Sunday collided with Earth on Tuesday, becoming the largest solar radiation storm since October 2003. NOAA's Space Weather Prediction Center has categorized the storm as "strong," or an S3, storm.  These storms can affect satellite operations and short wave radio propagation, but do not cause any harm to humans on Earth. Some polar flights, including a dozen Delta Air Lines planes, were re-routed to avoid communications lapses and exposing...
