It is early morning here. When will it get I guess Im the only one who doesn't understand the implications of this. Has this happened before and what were the results? Were there problems from it? Anything good come of it? Should we all throw ourselves under the wheels of the bus? Somebody speaka de english please. [/quote] Hi, well im tired and have to sleep but okay i will try it again^^ [b]First some basics:[/b] When the Sun produces a Coronal Mass Ejection (CME), the ejection sends solar winds out into space. The solar winds sent out by a CME carry with it it's own magnetic field called the Interplanetary Magnetic Field (IMF) and solar particles (density). The strength of the CME is what determines how strong the Solar Winds are and the density varies with each CME. The stronger the CME is, the stronger the solar wind IMF is. If a CME is Earth directed, it then sends those Solar Winds and IMF in Earths direction. The IMF is not constant and changes in strength and polarity (north/south) orientation. This simulation shows the effects of Solar Flares and CME's on Earths Magnetosphere in real time. (Note: Earth facing magnetic filament eruptions and coronol hole's also effect Earths magnetosphere. Do a search to learn more about these events) [b]a Solar Flare and CME are NOT the same.[/b] [b]A solar Flare [/b]is a eruption of intense high-energy radiation from the sun's surface and reaches Earth very fast, in around 8 minutes. The levels of Flare strength are A, B, C, M and X (in order of weakest to strongest). [b]A CME (coronal mass ejection)[/b] is an ejection of material from the solar corona, usually observed with a white-light coronagraph. A CME may or may not be produced by the sunspot explosion. If it does produce a CME, it takes anywhere from 2 to 3 days to reach Earth, and sometimes even longer ----------------------------------------------------------- :cmenov26: okay a majority of the CME was directed to the west and away from Earth, however this full halo event does have a weaker Eastern flank which may still impact Earth within 48 hours While Earth does not appear to be in the path of the core CME,so it will be a flank impact This happend not the first time but its worth to watch for us solar watchers or call us suntards It was very interesting to see how this cme happend Caused by a filament explosion :giffilamentnov26: You ask also..: "Anything good come of it?" yep, we can see auroras tommorow Watch it here: http://www.earthcam.com/cams/iceland/reykjavik/# Hope i helped you a bit Good Night all:grouphug: [/quote] :hf: [/quote]
