Strongest solar flare in decade causes blackouts

  Strongest solar flare in decade causes blackouts Two "significant" solar flares have blasted out of the Sun, including one which was the most powerful since 2006. Solar flares are powerful bursts of radiation and they disrupted radio communications over large areas of the Earth, said the Space Weather Prediction Centre (SWPC).The SWPC said high-frequency radio experienced a wide area of blackouts, loss of contact for up to an hour over the sunlit side of Earth, and low frequency communication, used in navigation, was degraded for an hour.NASA says radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground.

It is the strongest solar flare yet for 2012. According to Phillips, the big X5.4 solar flare erupted from the giant active sunspot AR1429, which was also responsible for the major sun storm on Sunday.

The sun blasted out seven massive solar flares in as many days in an extraordinary period of space weather that has sparked stunning geomagnetic storms above the earth.

Between September 4 and September 11, NASA observed seven flares, all classed in its strongest “X” category, with the most impressive registering at X9.3, a very significant event.

The latest, at X8.2 also a significant flare, peaked at 12:06 p.m. EDT on Sept. 10. It prompted warnings of possible radio blackouts from the Space Weather Prediction Center, which also issued a geomagnetic storm warning for Wednesday and Thursday.

X-class solar flares are the strongest solar storms the sun experiences. A burst of solar material leaps off the left side of the sun in what’s known as a prominence eruption . The sun erupted with two of the strongest solar flares it can unleash Friday (Oct.

Solar flares occur when a buildup of magnetic energy on the sun is suddenly released. They usually erupt from sunspots, temporary dark and relatively cool patches on our star's surface where the local magnetic field is very strong . Flares generate a burst of radiation across a wide range of the

The X9.3 solar flare was named by NASA as the strongest so far in the current solar cycle, a roughly 11-year period that began in December, 2008. The solar activity has been linked to increased aurora activity in the northern skies.

“The current solar cycle ... is now decreasing in intensity and heading toward solar minimum,” NASA said, “This is a phase when such eruptions on the sun are increasingly rare, but history has shown that they can nonetheless be intense.”

All the flares have emerged from the same “active region” of the sun, dubbed AR2673.

These events have been extremely intense, but none has caused serious disruption on Earth, and there’s no indication that the solar situation is going to get worse.

But that won’t always necessarily be the case in the future. In 1989, Canada’s Quebec state faced a nine-hour blackout from a solar event called a Coronal Mass Ejection.

Solar flares could also disrupt communications, including crucial satellite guidance system that could affect airplanes.

Many asteroids between Jupiter and Mars can claim one of those characteristics (orbiting one another or releasing vapor), but this is the first time that researchers have identified an object with both features, the researchers said.
