found this artical on aanother site, dont know if it old news or what but tought it was an interesting read and its about solar activity
When probing the deepest reaches of the Cosmos or magnifying our understanding of the quantum world, a whole host of mysteries present themselves.
This is to be expected when pushing our knowledge of the Universe to the limit.
But what if a well-known -- and apparently constant -- characteristic of matter starts behaving mysteriously?
Discovery - This is exactly what has been noticed in recent years; the decay rates of radioactive elements are changing. This is especially mysterious
as we are talking about elements with "constant" decay rates -- these values aren't supposed to change. School textbooks teach us this from an early
This is the conclusion that researchers from Stanford and Purdue University have arrived at, but the only explanation they have is even weirder than
the phenomenon itself: The sun might be emitting a previously unknown particle that is meddling with the decay rates of matter. Or, at the very least,
we are seeing some new physics.
A solar eruption sends a wave of plasma hurtling towards Earth on August 1st, 2010.
The event was captured by NASA satellites and explained by Discovery News Space Producer Ian O'Neill.
Many fields of science depend on measuring constant decay rates. For example, to accurately date ancient artifacts, archaeologists measure the
quantity of carbon-14 found inside organic samples at dig sites. This is a technique known as carbon dating.
Carbon-14 has a very defined half-life of 5730 years; i.e. it takes 5,730 years for half of a sample of carbon-14 to radioactively decay into stable
nitrogen-14. Through spectroscopic analysis of the ancient organic sample, by finding out what proportion of carbon-14 remains, we can accurately
calculate how old it is.
But as you can see, carbon dating makes one huge assumption: radioactive decay rates remain constant and always have been constant. If this new
finding is proven to be correct, even if the impact is small, it will throw the science community into a spin.
Interestingly, researchers at Purdue first noticed something awry when they were using radioactive samples for random number generation. Each decay
event occurs randomly (hence the white noise you'd hear from a Geiger counter), so radioactive samples provide a non-biased random number generator.
However, when they compared their measurements with other scientists' work, the values of the published decay rates were not the same. In fact, after
further research they found that not only were they not constant, but they'd vary with the seasons. Decay rates would slightly decrease during the
summer and increase during the winter.
Experimental error and environmental conditions have all been ruled out -- the decay rates are changing throughout the year in a predictable pattern.
And there seems to be only one answer.
As the Earth is closer to the sun during the winter months in the Northern Hemisphere (our planet's orbit is slightly eccentric, or elongated), could
the sun be influencing decay rates?
In another moment of weirdness, Purdue nuclear engineer Jere Jenkins noticed an inexplicable drop in the decay rate of manganese-54 when he was
testing it one night in 2006. It so happened that this drop occurred just over a day before a large flare erupted on the sun.
Did the sun somehow communicate with the manganese-54 sample? If it did, something from the sun would have had to travel through the Earth (as the
sample was on the far side of our planet from the sun at the time) unhindered.
The sun link was made even stronger when Peter Sturrock, Stanford professor emeritus of applied physics, suggested that the Purdue scientists look for
other recurring patterns in decay rates. As an expert of the inner workings of the sun, Sturrock had a hunch that solar neutrinos might hold the key
to this mystery.
Sure enough, the researchers noticed the decay rates vary repeatedly every 33 days -- a period of time that matches the rotational period of the core
of the sun. The solar core is the source of solar neutrinos.
It may all sound rather circumstantial, but these threads of evidence appear to lead to a common source of the radioactive decay rate variation. But
there's a huge problem with speculation that solar neutrinos could impact decay rates on Earth: neutrinos aren't supposed to work like that.
Neutrinos, born from the nuclear processes in the core of the sun, are ghostly particles. They can literally pass through the Earth unhindered as they
so weakly interact. How could such a quantum welterweight have any measurable impact on radioactive samples in the lab?
In short, nobody knows.
If neutrinos are the culprits, it means we are falling terribly short of understanding the true nature of these subatomic particles. But if (and this
is a big if) neutrinos aren't to blame, is the sun generating an as-yet-to-be- discovered particle?
If either case is true, we'll have to go back and re-write those textbooks.

I am sorry that I have not been on for the last week and a bit. I have been horribly ill, and just now feeling better. Unfortuantely, I am leaving
today on a week long trip today, so I am asking any of the regulars on here to keep posting any cool news or solar related events.
The sun is getting really active again with 4 sunspots currently facing us, a solar wind that is sparking some minor Northern Lights, the M-3 flare
from this weekend that Phage posted, and a monster filament on the sun right now:
MEGA SOLAR FILAMENT: An awesome, monstrous, jaw-dropping, 400,000 km long filament of magnetism is stretched across the sun's southern hemisphere. If
it collapses or erupts, as filaments often do, the result could be an Earth-directed coronal mass ejection. Meanwhile it is a fine target for backyard
"GEOMAGNETIC STORM WARNING: NOAA forecasters estimate a 40% chance of severe geomagnetic storms around the poles on Oct. 25th. The forecast is
prompted by a possible double whammy: both a solar wind stream and a CME could hit Earth's magnetic field on that date. High-latitude sky watchers
should be alert for auroras. "
Looks like we may have some communication disruptions and maybe some aurora's! I had noticed the FM radio have traffic break in from people talking on
radio's for businesses . . . hmmm. I will check it out tonight and tomorrow night for the aurora. I hope nothing happens to the power grid, I have got
a lot of worked scheduled for the plant!
It could be a double whammy of a Solar Storm and CME event!! Yikes! But, I think will all still be here on the 26th!

Thanks so much for the info - will definitely keep in touch here for updates. My boyfriend is a Ham operator, I just informed him of the event.
Keeping my fingers crossed on the power grid not being affected.
"ACTIVE SUNSPOT: Old sunspot 1112 is back and it is crackling with C- and M-class solar flares: SDO movie. So far none of the blasts has been
geo-effective because of the sunspot's location on the sun's eastern limb. Solar rotation is, however, turning the active region toward Earth, so stay
A visual message to mankind from Yahweh and His Holy Angelic forces. See the profile of the Lion? Other messages are encoded within. It's a visual
sign in the heavens including WAR.
Yahweh is getting ready to take on those ruining the Earth, and let everyone know where the crap flying at this planet comes forth from.
Watch as things become much worse as Yahweh pours out His wrath upon mankind leading up to Armageddon. It is His will that you all know exactly where
it is coming from.
Matthew 10:34 "Don't assume that I came to bring peace on the earth. I did not come to bring peace, but a sword."
Exodus 15:3 "The LORD is a warrior; Yahweh is His name."
"There will be no peace on Earth until My Son's Kingdom. I will crush every kingdom now standing and rock the earth off its foundation. I Yahweh
will destroy every enemy to My throne, and who can stop Me? Who can turn back My anger? No one." - Yahweh
The International Space Weather Initiative
"Nov. 8, 2010: Prompted by a recent increase in solar activity, more than a hundred researchers and government officials are converging on Helwan,
Egypt, to discuss a matter of global importance: storms from the sun. The “First Workshop of the International Space Weather Initiative (ISWI)”
meets Nov. 6th through 10th and is convened by the United Nations, the National Aeronautics and Space Administration (NASA), and the Japan Aerospace
Exploration Agency (JAXA)."
"Strong solar storms can knock out power, disable satellites, and scramble GPS," says meeting organizer and ISWI executive director Joe Davila of
NASA's Goddard Space Flight Center. "This meeting will help us prepare for the next big event."
New sunspots forming, could cause C class flares over next couple of days.
Two days ago, sunspot 1130 didn't exist. Now the fast-growing sunspot group is the largest visible feature on the sun's disk with twin cores
both larger than Earth.
If the magnetic field becomes unstable and explodes, as sunspot magnetic fields often do, a cloud of plasma could come flying toward Earth. This
active region merits watching for the next few days until the sun's rotation turns it away from our planet.
Thinking it is safe to say that there has been a noticable increase in Sun activity recently. As expected by scientists/astronomers. Shows,
documenteries, and CNN specials letting us know just how likely a severe conequence to Earth and our electrical grid is during the upcoming peak
Knowing that the Sun is entering a cyclic activity peak during 2012, that means the window between now and the end of 2012 first part of 2013 will
likely bring a crap load of events. Getting more intense as we move closer to 2012.
I am far from being any kind of expert on the sun, but have become convinced that we will see some major events via the Sun in the near future.
