Tempest on the Sun: Flurry of Small but Spectacular Solar Storms Captured by Nasa
A flurry of solar flares has been spotted on the sun by a Nasa telescope. In just one day more than half a dozen were spotted, in addition to several ejections of material. Videos and images show the explosions in all their glory as material races from the sun’s surface into the surrounding space. http://i.dailymail.co.uk/i/gif/Syed_GIFs/flare.gif According to Nasa's Solar Dynamics Observatory (SDO) team a single, dynamic active region unleashed over half a dozen solar flares in about 24 hours from 25 to 26 August. -The two larger flares were M-class (moderate) flares and the others were smaller flares. This animation shows an ejection associated with the flares Quote:
The flares originated from a sunspot called AR2151, an intense region of magnetic activity on the sun’s surface. Solar flares are powerful bursts of radiation, but thanks to Earth’s atmosphere they pose little threat to people on the planet’s surface. However intense flares can be known to disrupt satellites in Earth orbit. Periods of intense solar activity can result in bigger and more visible auroras, as more solar wind interacts with particles in the atmosphere. http://i.dailymail.co.uk/i/pix/2014/...43_636x358.jpg http://i.dailymail.co.uk/i/pix/2014/...04_171_jpg.jpg The flare under study can be seen on the middle-left of the sun in this image. Solar flares are releases of intense high-energy radiation from the sun, which we see as a bright light. -They are sometimes accompanied by an emission of material known as a coronal mass ejections (CME) http://i.dailymail.co.uk/i/pix/2014/...AIA131_jpg.jpg One of the flares as spotted by Nasa's Solar Dynamics Observatory (SDO) can be seen up close here. Periods of intense solar activity can result in bigger and more visible auroras, as more solar wind interacts with particles in Earth's atmosphere According to Noaa’s Space Weather Prediction Centre this particular event, while impressive, the flares didn’t pose much threat to our planet. ‘Given the location of this event, the associated coronal mass ejection is well off the sun-Earth line and no significant geomagnetic storming is anticipated as a result,’ they reported. ‘Region 2151 had a history of M-class flare production on its previous rotation. ‘This event is indicative of an uptick in activity from relatively quiet conditions as of late, though. ‘The sun is currently peppered with relatively small regions, all of which are unlikely producers of severe activity at this time.’ http://i.dailymail.co.uk/i/pix/2014/...Observator.jpg Nasa's Solar Dynamics Observatory (SDO), artist's illustration shown, has has been in a distant Earth orbit since 11 February 2010. It will observe the sun until at least 2015, after which its mission could be extended. Its goal is to understand the influence of the sun on Earth and surrounding space by monitoring its atmosphere A Fascinating Flurry of Solar Flares Captured by NASA: https://www.youtube.com/watch?v=u4bmN7T0lHs . https://www.youtube.com/watch?v=u4bmN7T0lHs |
