Sun has biggest solar flare of the year

If you live at a high northern or southern latitude, watch for some spectacular lights in the sky Tuesday night.

The sun unleashed its strongest solar flare of the year Sunday, and the cloud of radiation it spewed will hit Earth's magnetic field Tuesday, NASA said.

NASA's Solar Dynamics Observatory recorded a brief but intense flash signaling the ejection of a cloud of ultraviolet radiation.

The source of the flare, sunspot 1158, is growing rapidly, the observatory reported.

    IS AL GORE GOING TO GET ANOTHER OSCAR AND NOBEL PEACE PRICE FOR THIS SOLAR FLARE? GEE, I HOPE SO...THE POOR GUY HAS BEEN SO DISCREDITED THAT HE NEEDS SOMETHING TO FILL HIS 12,000 SQUARE FOOT HOUSE HEATED WITH OIL AND ELECTRICITY.

    Maybe the sun is lost and sending out a flare for help.

    No I find this to be pretty alarming. If it keeps happening .. if the Sun keeps pushing our magnetosphere and bending down to the deck, we have less shields, crops die, weather changes, etc. So we need to watch this .. its serious. There is also some glimmer of science that our magnetosphere is weakening for some weird reason. The sun is really really big.. and we are really really tiny.

      If you're worried about THIS, you'd be shocked to know that THIS is a minor storm and bigger ones have hit MANY, MANY times.
      It'll NOT EVER hit the atmosphere. Period. It won't hurt crops. It won't make the air stinky.
      A SEVERE storm COULD pop the power systems in Canada and the northern US.
      The magnetic field of the Earth IS fading. It never REACHES zero, but eventually will reverse. Figure a few hundred thousand years, then you'll need a new compass. During minimal strength, the magnetosphere will remain intact, as it is a planetary average field, not the surface magnetic field.
      So, were it to reverse TODAY, which it won't, the worst damage we'd have would be paying for new maps showing which way magnetic north is and new compasses reversing north and south.

      yep, nothing unusual, it is the first of this solar cycle...e.g. a more powerful X6 happened in July 2000...

      The North Pole is migrating into Siberia so the weather patterns will continue to change. This flare is no big deal. I'm just waiting for North America to get warmer already.

      Books are your friend. Read about the magentosphere and what happens when plasma hits it. Then post...

      Hey Art....the funny thing is that these effeminate guys with white hair keep showing up at my house, creating havoc with my kids and keep handing them these glossy black rocks. But I chase them away by screaming bloody murder but they always come back in the middle of the night. I can't get ANY sleep with these gusy hanging around.

    Can I just say, you guys are all hilarious! : D Interestingly though, this May thru Oct. is suppose to begin a period of the most intense solar flares since the 1950's. It's worth a look on the NASA website.

      THIS solar maximum COULD get rather expensive for satellite operators though.
      Might even pop power up in Canada and the northern US.

    1950s?

    Isn't that when Globull Warming started?

    I like that it's only February and they say "biggest solar flare of the year". We still got 10 months to go

    What?? A solar flare?? Does this mean we have to stock up on canned goods again? I'm still trying to make my way through my Y2K stash....

    Wish they'd give a time of when this thing's supposed to hit, so I'm less confused when my satellite goes down...
