Space Weather News for April 3, 2006
http://spaceweather.com Solar activity is suddenly increasing. The biggest sunspots of the year are crossing the solar disk; one group is longer than 10 Earth diameters and poses a threat for solar flares. Meanwhile, astronomers are monitoring a large and delightfully complex prominence dancing long the sun's limb. Whether all this will translate into magnetic storms and auroras remains to be seen. Please visit http://spaceweather.com for pictures and updates. Would you like to know about solar flares the instant they erupt? Sign up for SpaceWeather PHONE: http://spaceweatherphone.com |

You're right, should not be taken too lightly especially by anyone in space.
since it is unlikely you or I will ever be in that general neighborhood however, we can take it as lightly as we please! : } "Verstaldin" wrote in message ... While prominences and flares can be exciting in an esthetic sense, the reality behind those beautiful pitcures is terrifying. It is a good thing earth has a magnetic field as strong as it is today. If we were like Mars, anyone living on the surface might be fried by radiation or die of cancers caused by it. It shouldnot be taken lightly. Also, its effects on vital communications can be pretty potent as well. All life all holiness come from you O Lord http://pwp.surfglobal.net/mjmiller/index.htm "Lisa Simpson" wrote in message . ..

... While prominences and flares can be exciting in an esthetic sense, the reality behind those beautiful pitcures is terrifying. Our local star is wonderful and stable, but being that it is basically a gigantic nuclear reactor, it's also inherently nasty. The only reason we live in peace with it is because of our thick, protective magnetic field and our ozone layer. There are massive doses of UV, x-rays and gamma rays thrown out in one major x-class flare. Even some of the smaller solar flares are larger than the entire Earth. The bigger ones are larger than many Earths strung end-to-end. Our observatory has a telescope that is specifically designed to look at the Sun in a specific wavelength of light, known as hydrogen alpha (H-alpha). It only allows you to view in a certain small slice of light wavelength (the alpha emission line in the red end of the spectrum), but that is where all the action is. When the Sun is really active, you can see solar flares, prominences and even the boiling "granulation" that marks the photosphere* of the Sun through this scope. You can see the surface of the Sun literally change before your eyes. Four years ago when the Sun was more active than now, I was watching gigantic loops of superheated hydrogen gas coming out of sunspots and looping back into them again. To see that kind of detail from the Earth just takes your breath away. Here's a picture pretty similar to what I saw: http://www.space.com/scienceastronom...te_000926.html Jackie *The Sun technically has no solid surface, but what appears to us as a surface, we refer to as the photosphere. |

No one knows for sure how long this takes. It could be months or years. There will also be a higher risk of skin cancer during the reversal period and compasses will be almost useless. Fortunately we have alternatives to the compass these days. |

Archeologist people have found Human fossils that date back to between
five million years and six million years.I believe Humans will exist on Earth for at least another five to six million years.Perhaps many,many more millions of years,unless some unknown something out there in Space clobbers us all to smithereens.Klattu Baraba Nikto.All Your Base Are Belong To Us. cuhulin |

The worst that could happen back then was a bad sunburn or possibly death from skin cancer. The stakes are much higher now. realy? look chicken little get a grip |
