Spectacular Sun Show

Last week our nearest star put on the most spectacular of shows, under the ever-watching eyes of solar observers, the sun erupted in an awesomely powerful M2-class solar flare, only classed as a medium explosion.

Last week our nearest star put on the most spectacular of shows, under the ever-watching eyes of solar observers, the sun erupted in an awesomely powerful M2-class solar flare, only classed as a medium explosion.

Not that this event seemed minor, erupting as it did from an active sunspot region, highly stressed and concentrated magnetic fields being forced through surface of the star known as the photosphere. These fields push the hot plasma out of the way, exposing cooler plasma behind and resulting in  a massive CME – coronal mass ejection.

 

Lots of the plasma however failed to escape the sun’s own gravity, being dragged back down as a vast cloud of cooler, darker plasma, at around 80,000 degrees, as compared to the million degree coronal plasma. This cloud rained back into the photosphere, sparks of sudden plasma heating as the dense plasma at the surface was impacted by huge blobs of gas.

What did get away from the sun during that CME is now rushing toward earth at 2.5million mph, taking a little under 40 hours to reach here, deliver what astronomers call a glancing blow that  potentially could cause spectacular aurora activity, though only minor interference to communications, satellites and potentially power grids, the impact fairly small as these things go.

    Good article, but where’s the video?

    I don’t know what happened here. No video for me. Failed to embed? Correct YouTube video link is http://www.youtube.com/watch?v=Q_3u_0NN7OM
