NASA VIDEO: Sun Unleashes 'Monster Eruption'

Intense.

The sun unleashed a monster eruption of super-hot plasma Friday (Nov. 16) in back-to-back solar storms captured on camera by a NASA spacecraft.

The giant sun eruption, called a solar prominence, occurred at 1 a.m. EST (0600 GMT), with another event flaring up four hours later. The prominences was so large, it expanded beyond the camera view of NASA's Solar Dynamics Observatory (SDO), which captured high-definition video of the solar eruption.

"The red-glowing looped material is plasma, a hot gas made of electrically charged hydrogen and helium," officials with NASA's Goddard Space Flight Center, which oversees the SDO mission, explained in a description. "The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma."

Let me guess. Global warming caused this eruption.

Funny Cheyenne. I did some electrical work at the MIT Fusion lab and got to see their reactor. The 3 input bus bars were solid copper and about 12" wide x15" high or there about (my recollection) and had the be sized in that fashion to handle the amperage. They used RF energy (I believe it was in the range of 1-1.5 million watts RF) to cause the reaction which lasted about a millionth of a second or so.

It was impressive and glad they gave me the tour.

Thankfully that blast of plasma did not come towards us. I have read where there was a solar storm at the beginning of the 1900s that pretty much wiped out lines and communications across the continent. This was of course in the infancy of power transmission lines. There has been some discussion as to whether or not the grid could take that kind of punishment from an intense storm such as this one. Don't know if they have built any safeguards into the system or not. I am sure John, the resident Tesla could fill in that void with some good information.

Meant that with all due respect John. You seem to know a lot about this stuff. Lotta technical stuff that is.

No sweat Skin, I know that no offense was intended. Kids should know about this stuff too but it seems that science and economics take a back seat to corporatism in schools.. I will never take offense to anything here and I know better...until Bill McKibben or associates decide to comment here. Then look the fuck out. Then you will see me use this special tag "Irish Spring Ivory Soap".

And then rub their nose in it....

Here is a good site for monitoring space weather. It has great real time videos and other technical info.

Currently sunspot activity:

ANOTHER FAST-GROWING SUNSPOT: The sunspot number is increasing again. During the past 36 hours, active region AR1618 has more than quadrupled in size. It now has more than a dozen dark cores scattered across an expanse of stellar surface more than 10 times wider than Earth...

...The sunspot has also developed a 'beta-gamma' magnetic field that harbors energy for strong solar flares. NOAA forecasters estimate a 30% chance of M-class flares and a 5% chance of X-flares during the next 24 hours. Because of the sunspot's nearly central location on the solar disk, any eruptions will likely be Earth-directed.

John, perhaps we should wear sun screen. I prefer butter. It scalds the outside so that the juices remain inside. Sort of like cooking a turkey. Happy Thanksgiving to all you Bailers out there. Remember, fill bucket, dump, repeat in time contiuum until we reach zero.

If that was my neighborhood the attacks would be very short lived and the freezers would be full. You got to love the new society, sissies everywhere.

Gomp. My Mom moved us from the city in the early 70's and we came to a small country town. One day while sitting in a local diner on Main Street there came in two fellas with .22 rifles and a bag of squirrels across their backs. They ordered a couple of dogs fries and a coke. That same diner is there but I would dare say that if those same fellas came in the same fashion that the police would show up in large numbers and arrest the hell out of them. They used to teach gun safety in schools back then. Now a kid can't even forget to take his pen knife out of his back pack if he has been camping for the weekend without being thrown out of school and arrested first. Completely out of hand.

Comet ISON

http://spaceweather.com

COMET ISON SPROUTS A TAIL: Comet ISON, which is plunging toward the sun for a bright and fiery encounter in late 2013, has just sprouted a tail. It's not much--yet--but that is because the comet is still in deep space near the orbit of Jupiter. On. Feb. 3rd, amateur astronomer Rolando Ligustri photographed the development using a robotic telescope in New Mexico:



Comet ISON doesn't look very impressive now as it glides through the cold vacuum more than 600,000 km from Earth, but its appearance will improve later this year. On Nov. 28th, ISON is going to glide through the sun's atmosphere only 1.1 million km above the stellar surface. It could emerge from the encounter glowing as brightly as the full Moon, visible in broad daylight near the sun. If so, today's budding tail would likely grow into a garish appendage that wows observers in both hemispheres--no telescope required. Stay tuned for updates.

Update: NASA's Deep Impact spacecraft has also observed Comet ISON's sprouting tail. Click here for a video.

This poses no hazard, but for those interested in science and what may be in the skies later this year...

Time Lapse Video: Comets Lemmon and PanSTARRS sweeping through the Southern Skies

http://vimeo.com/59571509

[snip]

Two comets - C/2012 F6 (Lemmon) and C/2011 L4 (PanSTARRS) can be seen moving through the Southern Sky in this short time lapse video. Hopefully comet PanSTARRS brightens up significantly before moving into the Northern Hemisphere sky.

Note: Be on the lookout for this third one in Oct-Jan.

Bigger things to worry about than global warming: Scientists say a destructive solar blast narrowly missed Earth in 2012

Video follows of the July 23rd, 2012 Coronal Mass Ejection, said to be the fastest ever

From UC BERKELEY — Earth dodged a huge magnetic bullet from the sun on July 23, 2012.

According to University of California, Berkeley, and Chinese researchers, a rapid succession of coronal mass ejections — the most intense eruptions on the sun — sent a pulse of magnetized plasma barreling into space and through Earth’s orbit. Had the eruption come nine days earlier, when the ignition spot on the solar surface was aimed at Earth, it would have hit the planet, potentially wreaking havoc with the electrical grid, disabling satellites and GPS, and disrupting our increasingly electronic lives.

This movie shows a coronal mass ejection (CME) on the sun from July 22, 2012, at 10:00 p.m. EDT until 2 a.m. on July 23 as captured by NASA’s Solar Terrestrial Relations Observatory-Ahead (STEREO A). Because the CME headed in STEREO A’s direction, it appears like a giant halo around the sun. NOTE: This video loops 3 times.
The solar bursts would have enveloped Earth in magnetic fireworks matching the largest magnetic storm ever reported on Earth, the so-called Carrington event of 1859. The dominant mode of communication at that time, the telegraph system, was knocked out across the United States, literally shocking telegraph operators. Meanwhile, the Northern Lights lit up the night sky as far south as Hawaii….

------------

Here is a video of another solar storm a few years ago that caused widespread blackouts and transformer damage. I used to build, maintain and test components in substations some years ago and can say that this video is spot on.
