Sun Update: M6,5 Solar Flare & CME Earth Directed
The Coronal Mass Ejection (CME) is visible within the new Lasco imagery.
The strongest solar flare in quite some time took place within the past couple of hours around Sunspot 1719. The moderately strong event measuring M6.5 took place at 07:16 UTC
Earth-directed CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when they connect with the outside of the Earth’s magnetic envelope, the magnetosphere, for an extended period of time.
The recent space weather also resulted in a weak solar energetic particle (SEP) event near Earth. These events occur when very fast protons and charged particles from the sun travel toward Earth, sometimes in the wake of a solar flare. These events are also referred to as solar radiation storms. Any harmful radiation from the event is blocked by the magnetosphere and atmosphere, so cannot reach humans on Earth. Solar radiation storms can, however, disturb the regions through which high frequency radio communications travel.
These pictures are from NASA, and Were taken from the AIA instrument of the satellite SDO (Solar Dynamics Observatory), with a wavelength of 304 Angstroms. this movie was produced by helioviewer org.
