Sun Update: Solar Flare Eruption at the South-East of the Sun SDO-AIA 304 – April.24,2013


When the moon shall have faded out from the sky, and the sun shall shine at noonday a dull cherry red, and the seas shall be frozen over, and the icecap shall have crept downward to the equator from either pole . . . when all the cities shall have long been dead and crumbled into dust, and all life shall be on the last verge of extinction on this globe; then, on a bit of lichen, growing on the bald rocks beside the eternal snows of Panama, shall be seated a tiny insect, preening its antennae in the glow of the worn-out sun, the sole survivor of animal life on this our earth — a melancholy bug.
- – - William Jacob Holland “The Moth Book” 1903

  
To believe in a child is to believe in the future. Through their aspirations they will save the world. With their combined knowledge the turbulent seas of hate and injustice will be calmed. They will champion the causes of life’s underdogs, forging a society without class discrimination. They will supply humanity with music and beauty as it has never known. They will endure. Towards these ends I pledge my life’s work. I will supply the children with tools and knowledge to overcome the obstacles. I will pass on the wisdom of my years and temper it with patience. I shall impact in each child the desire to fulfill his or her dream. I shall teach.
- – - Henry James

  


solar flare is a sudden brightening observed over the Sun‘s surface or the solar limb, which is interpreted as a large energy release of up to 6 × 1025 joules of energy (about a sixth of the total energy output of the Sun each second or 160,000,000,000 megatons of TNT equivalent, over 25,000 times more energy than released from the impact of Comet Shoemaker–Levy 9 with Jupiter). They are mainly followed by a colossal coronal mass ejection also known as a CME.[1] The flare ejects clouds of electrons, ions, and atoms through the corona of the sun into space. These clouds typically reach Earth a day or two after the event.[2] The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.

SOLAR WATCH: MONSTER SUNSPOT 1654 AIMS OUR WAY - EARTHQUAKE WINDOW OPENING AS CORONAL MASS EJECTIONS TO HIT EARTH ON 17th Jan!

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 go into the 18th. As it does so, aurora will be likely in the middle to upper north and south latitude locations.  Strangely, this coincides with Martin's earthquake window. "Using HS network and my own theory (posted here), we are getting close to the next larger quake in the Western North America region between Mexico and Alaska," said Martin. "because the CME from the Sun is joining in during the quake window, all indicators are showing up." Because all indications are showing up, Martin says it is "go time" for unsettled seismic activity. - The Weather Space Network.

CHANCE OF FLARES:
 NOAA forecasters estimate a 60% chance of M-class solar flares, and a 5% chance of X-flares today. The probable source would be big sunspot AR1654, which is squarely facing Earth. Sunspot AR1654 has a beta-gamma magnetic field that harbors energy for M-class solar flares. Space Weather.


SOLAR UPDATE: Solar activity is low with several low level C-Class flares detected around various locations across the visible solar disk. There will remain a chance for an isolated M-Class event around Sunspot 1654. A Coronal Mass Ejection (CME) is visible this morning in STEREO-Ahead COR2 imagery, however it does not look to be Earth directed at this time. A slow moving Coronal Mass Ejection (371 km/s) generated by a solar flare on Sunday morning, is expected to impact our geomagnetic field by January 17th. - Solar Ham.

Like an enormous cannon that is slowly turning its barrel toward us, the latest giant sunspot region AR1654 is steadily moving into position to face Earth, loaded with plenty of magnetic energy to create M-class flares—moderate-sized outbursts of solar energy that have the potential to cause brief radio blackouts on Earth and, at the very least, spark bright aurorae around the upper latitudes.

MONSTER SUNSPOT AIMING OUR WAY: According to SpaceWeather.com, AR1654 "could be the sunspot that breaks the recent lengthy spell of calm space weather around our planet." The image above, captured by NASA's Solar Dynamics Observatory earlier today, shows the structure of AR1654 upon the Sun's photosphere—its light-emitting "surface" layer. Stretching many tens of thousands of miles, this magnetic solar blemish easily dwarfs our entire planet. And it's not just a prediction that this sunspot will unleash a flare—it already has. AR1654 came around the limb of the sun crackling with activity. Shortly after the probability of AR1654 releasing a flare was raised to 50% it did just that, letting loose with a burst of magnetic energy that was observed by SDO's multi-channel cameras.  Peaking at 9:11 UTC, this M1-class flare won't have much more effect on Earth than perhaps some radio and GPS interference and maybe increased auroral activity. But AR1654 is still evolving and growing… and moving to face us. In the meantime, solar astronomers and observatories like SDO are keeping an ever-watchful eye on this magnetic monster. - PHYSORG.
