Giant Sunspot May Blast M-Class Solar Flares Towards Earth

Giant Sunspot May Blast M-Class Solar Flares Towards Earth

The fast-growing sunspot doubled in size in 24 hours and may produce medium-class flares.
     A sunspot nearly triple the size of Earth is within firing range of our planet, and may send out medium-class flares in the near future.

Major Solar Flare Causes Radio Blackout

Major Solar Flare Causes Radio Blackout 11-29-20


     Today, Earth-orbiting satellites detected the biggest solar flare in more than 3 years. The M4.4-category eruption produced a shortwave radio blackout over some parts of Earth and a bright coronal mass ejection (CME). Remarkably, the flare

was even bigger than it seemed. The blast site is located just behind the sun's southeastern limb, so the explosion was partially eclipsed by the body of the sun.

Geomagnetic Mega-Storm Fries Telegraph Lines – 156 Years Ago Today

Geomagnetic Mega-Storm Fries Telegraph Lines – 156 Years Ago Today

     On Sept. 2nd, a billion-ton coronal mass ejection (CME) slammed into Earth's magnetic field. Campers in the Rocky Mountains woke up in the middle of the night, thinking that the glow they saw was sunrise. No, it was the Northern Lights. People in Cuba read their morning paper by the red illumination of aurora borealis. Earth was peppered by particles so energetic, they altered the chemistry of polar ice.

Hard to believe? It really happened--exactly 156 years ago. This map shows where auroras were sighted in the early hours of Sept. 2, 1859:

Map of Auroras Sighted in Morning – Sept. 2, 1859

As the day unfolded, the gathering storm electrified telegraph lines, shocking technicians and setting their telegraph papers on fire. The "Victorian Internet" was knocked offline. Magnetometers around the world recorded strong disturbances in the planetary magnetic field for more than a week. [...]

Solar Flare Causes Strong HF Radio Blackout On The Dayside Of Earth 10-19-14

     Behemoth sunspot AR2192 has unleashed an X1-class solar flare. NASA's Solar Dynamics Observatory recorded the blast in this extreme UV image of the sun on Oct. 19th (0500 UT)(see above).

A pulse of ultraviolet and X-radiation from the flare caused a brief but strong HF radio blackout on the dayside of Earth, mainly over Asia and Australia. . . .

Intense Solar Eruption Captured by NASA Spacecraft (Video)

      A huge tendril of super-hot plasma that had been creeping across the face of the sun erupted Tuesday (Sept. 2) in a striking solar storm that may send a wave of charged particles in Earth's direction.

Video of the solar eruption captured by NASA's sun-watching Solar Dynamics Observatory shows a cloud of solar plasma being hurled from the sun's surface during the rippling blast.

Debris from the solar explosion could be traveling in the direction of Earth, according to Spaceweather.com, which tracks stargazing and space weather events. Further observations should confirm whether the eruption was actually an Earth-directed coronal mass ejection, or CME. . . .

Massive Solar Blast that Almost Wreaked Havoc on Earth

The Massive Solar Blast that Almost Wreaked Havoc on Earth

     Earth dodged one of the most massive magnetic solar bursts ever on July 23, 2012, scientists with the University of California, Berkeley revealed on Wednesday -- saving the planet from widespread havoc.

"Had it hit Earth, it probably would have been like the big one in 1859, but the effect today, with our modern technologies, would have been tremendous," UC Berkeley research physicist Janet G. Luhmann said in a press release.

According to researchers had the quick succession of coronal mass ejections, the most intense kind of solar eruptions, come nine days earlier, it would have hit Earth, potentially disabling satellites and GPS and the electrical grid.

A study from last year revealed that a solar storm like the one Earth narrowly avoided could have cost up to $2.6 trillion in damages. A similar event in March 1989 caused Canada's Hydro-Quebec power grid to collapse and left six million people with no electricity for nine hours.

"The cost of an extreme space weather event, if it hits Earth, could reach trillions of dollars with a potential recovery time of 4-10 years," professor at China's State Key Laboratory of Space Weather Ying D. Liu warned in a press release. "Therefore, it is paramount to the security and economic interest of the modern society to understand solar superstorms." . . .

Huge Sunspot Targets Earth

A 4-day movie of AR1944 from the Solar Dynamics Observtory

     Giant sunspot AR1944 erupted on Jan 7th at approximately 1832 UT, producing a powerful X1-class solar flare. First-look coronagraph images from the STEREO-Ahead spacecraft appear to show a coronal mass ejection (CME) emerging from the blast site. If so, the CME is almost certainly heading for Earth. . . ..

Rocky Raybell photographed the active region named "AR1944" yesterday from his backyard in Keller, Washington.

The sprawling sunspot contains dozens of dark cores, the largest big enough to swallow Earth three times over. This makes it an easy target for amateur solar telescopes -- or even regular cameras. Raybell used an SX40 digital camera on a tripod whole holding a Baader solar filer over the lens to capture his image. . . .

UFO NEWS | VIDEO | Cloaked UFO or Left Over Artifact From Image Processing

     On Dec. 1, a camera onboard NASA's Stereo spacecraft recorded a wave of electrically charged material shooting out from the sun and blasting Mercury. Footage of this "coronal mass ejection" (CME), as such events are called, has caught the attention of alien-hunters, who say it has unveiled a giant, "cloaked" spaceship parked near the solar system's innermost planet. . . .

. . . As you might suspect, there is a non-UFO explanation of the apparent flare-up near Mercury. According to Russ Howard, head scientist of the NRL group, and Nathan Rich, lead ground systems engineer, it is simply an artifact left over from the way raw HI-1 telescope data gets processed. Rather than a UFO mothership parked near Mercury, the bright spot is "where the planet was on the previous day," Rich told Life's Little Mysteries. . ..
