Earth-directed solar X-flare March 11

The sun has been relatively quiet, and this is the first X-flare of 2015. It caused a brief radio blackout at some frequencies. Possible aurora alert ahead.

The first X-flare of 2015 from NASA's Solar Dynamics Observatory

A strong Earth-directed X-flare erupted from a large active region on the sun – AR2297 – earlier today. The flare happened on March 11, 2015 at 16:22 UTC (11:22 a.m. CDT). It measured X2 on the Richter Scale of Flares. Spaceweather.com said:

Extreme ultraviolet radiation from the explosion ionized the upper layers of Earth’s atmosphere, causing HF radio fade-outs and other propagation effects on the dayside of our planet. In the red zone of this map, ham radio operators and mariners may have noticed brief but complete blackout conditions at frequencies below 10 MHz.

The disturbance has since subsided.

Spaceweather.com also said that natural radio emissions from the sun indicate a possible coronal mass ejection – CME – emerging from the blast site at speeds exceeding

Solar Flare Disrupts Radio Waves On Earth

coronal mass ejection

A solar flare drowned out radio communications on Earth on February 2. The relatively “tiny” sun spot erupted into a moderately sized Class-C coronal mass ejection. The sound of the waves created by the solar flare cloaked radio waves between 28MHz and 21.1 MHz.

The voices going across the impacted radio signals appeared to be “swallowed” by the solar flare, Wired notes. NASA JOVE project radio astronomer Thomas Ashcraft noted how interesting the sound was as the wave from the coronal mass ejection (CME) rolled through.

As previously reported by The Inquisitr, the sun is entering the Read more…

SOLAR WATCH: Monster Sunspot 1654 Aims Our Way – Earthquake Window Opening As Coronal Mass Ejections To Hit Earth On Thursday!

January 15, 2013 – THE SUN – Simulations of a coronal mass ejection (CME) show the impact arrival of such on January 17th. This coincides with Senior Meteorologist Kevin Martin’s window for an earthquake in North America. The Sun is acting up again, with large sunspots moving across the solar disk. The sunspots are powerful enough for x-class solar flares, the most powerful of them all.

While a 10% chance is now given for such a flare, one is already on the way. This should impact on January 17th and Read more…

Sunspot AR1654 Getting Bigger, Unleashes Solar Flare In M1-Class Blast, NASA Officials Say

Solar Flare

This view of the flare on Jan. 11, 2013, was recorded by NASA’s Solar Dynamics Observatory.

The surface of the sun erupted in a solar flare early today (Jan. 11), unleashing a blast of super-heated plasma into space.

A huge sunspot known as AR1654 produced the M1-class flare at 4:11 a.m. EST (0911 GMT), officials with NASA’s Solar Dynamics Observatory said in a description of the event. The SDO spacecraft is one of several sun-watching space telescopes keeping tabs on solar flares and other sun weather events.

According to Spaceweather.com, sunspot AR1654 is growing more active and is now “crackling with M-class solar flares” like the one that erupted today.

“AR1654 is getting bigger as it turns toward Earth Read more…

Huge SUNSPOT 1476 poses a threat(Video)

May 8, 2012 Comments off

spaceweather.com

BIG SUNSPOT: One of the largest sunspot groups in years rotated over the sun’s northeastern limb this weekend. With a least four dark cores larger than Earth, AR1476 sprawls more than 100,000 km from end to end, and makes an easy target for backyard solar telescopes. Amateur astronomer Alan Friedman sends this picture of the behemoth from his backyard in Buffalo, NY: “AR1476 is firecrackler,” says Friedman. Indeed, the active region is crackling with impulsive M-class solar flares. Based on the sunspot’s complex ‘beta-gamma’ magnetic field, NOAA forecasters estimate a 75% chance of Read more…

In the last week or so we’ve been reporting on solar flares that have been released and solar storms impacting earth, with more intense northern lights displays and concerns that radio communications and satellites could be disrupted. We can now tell you that yesterday the largest solar flare yet of 2012 occurred, this time an Read more…
