Finding that "something" has been a goal of researchers for decades. In the 1970s and 80s, observations by two German/US Helios spacecraft set the stage for early theories, which usually included some mixture of plasma instabilities, magnetohydrodynamic waves, and turbulent heating. Narrowing down the possibilities was a challenge. [b]The answer, it turns out, has been hiding in a dataset from one of NASA's oldest active spacecraft, a solar probe named Wind. Launched in 1994, Wind is so old that it uses magnetic tapes similar to old-fashioned 8-track tapes to record and play back its data.[/b] Equipped with heavy shielding and double-redundant systems to safeguard against failure, the spacecraft was built to last; at least one researcher at NASA calls it the "Battlestar Gallactica" of the heliophysics fleet. Wind has survived almost two complete solar cycles and innumerable solar flares. [b]"After all these years, Wind is still sending us excellent data," says Szabo, the mission’s project scientist, “and it still has 60 years' worth of fuel left in its tanks.”[/b] (snip) [b][color=darkred]"I think we found it," he says. "The source of the heating in the solar wind is ion cyclotron waves."[/color][/b] Ion cyclotron waves are made of protons that circle in wavelike-rhythms around the sun's magnetic field. According to a theory developed by Phil Isenberg (University of New Hampshire) and expanded by Vitaly Galinsky and Valentin Shevchenko (UC San Diego), ion cyclotron waves emanate from the sun; coursing through the solar wind, they heat the gas to millions of degrees and accelerate its flow to millions of miles per hour. Kasper's findings confirm that ion cyclotron waves are indeed active, at least in the vicinity of Earth where the Wind probe operates. Ion cyclotron waves can do much more than heat and accelerate the solar wind, notes Kasper. [b][color=darkred]"They also account for some of the wind's very strange properties."[/color][/b] The solar wind is not like wind on Earth. Here on Earth, atmospheric winds carry nitrogen, oxygen, water vapor along together; all species move with the same speed and they have the same temperature. The solar wind, however, is much stranger. [b]Chemical elements of the solar wind such as hydrogen, helium, and heavier ions, blow at different speeds; they have different temperatures; and, strangest of all, the temperatures change with direction. [/b] "[b][i]We have long wondered why heavier elements in the solar wind move faster and have higher temperatures than the lighter elements," says Kasper. "This is completely counterintuitive[/i][/b]." The ion cyclotron theory explains it: Heavy ions resonate well with ion cyclotron waves. Compared to their lighter counterparts, they gain more energy and heat as they surf. more here: http://science.nasa.gov/science-news/science-at-nasa/2013/08mar_solarwind/ (solar) WIND Mission homepage: http://pwg.gsfc.nasa.gov/wind.shtml Just for a hoot, here's the WIND Daily data plot for March 12. 2012 (the big magnetic storm): http://cdaweb.gsfc.nasa.gov/cgi-bin/gif_walk [/quote] Nice post Hugh, makes quantum seem off center doesn't it. [/quote] Good Article SolStar Hugh:sun: Highlighted:Ridiculous statement,of course it is intuitive that heavier Elements move faster that the lighter ones as they have more Electrons hence more Electrons to shed to produce the Ion Wind - This is what happens,no? - As The Sun hurtles out 'Particles/Elements' they are exited enough to form their own counter part SEPs' through the energies involved that release the inherent energies they contain,no? :scratching: :sun: [/quote] I'm somewhat limited in science education, but as I'm reading what Hugh posted, all that came to mind was my 7TH grade physical science class and an awesome teacher showing us how "excited" atoms created energy and heat. Is it such a revelation that the same would occur in space ? Am I missing or over simplifying something here ??? [/quote]

We have just had another huge X flare measuring at a X8.2 originating from sunspot 2673
On September 11, 2017
[

]
ALL flares recorded ARE Earth facing regardless of where the sunspot is located
-----------
CME FROM X9 HAS ARRIVED!
Issue Time: 2017 Sep 07 2242 UTC
WARNING: Geomagnetic Sudden Impulse expected
Valid From: 2017 Sep 07 2255 UTC
Valid To: 2017 Sep 07 2330 UTC
IP Shock Passage Observed: 2017 Sep 07 2229 UTC
On September 6th we have had 2 X flares! A X2.2 at 09:10 utc & a secend larger flare just a few hours later of X9.3 at 12:02 utc. There is a large widespread Earth directed CME associated with this latest X flare as we can see here

An update as to the arrival time of this CME will be added once all data has been reviewed.
The X9.3 flare is the 14th largest X flare ever recorded!
On September 4th we had 7 M flares from fast growing sunspot 2673, with at least 1 large dense Earth directed CME. This CME will arrive late in the day on Wednesday September 6th.
There is now a 25% chance for X flares over the next 24hrs & 71% chance for M flares
We have a Long Duration M2.4 Solar Flare starting
01:05 UTC July 14th 2017
There was a full halo CME observed with this solar flare. The associated CME is Earth Directed. See discussion on the last page for all updates!
