A space weather physicist, Dr. Tamitha Skov, recently posted a video on her Twitter handler showing that a giant filament of solar plasma had broken off the sun’s surface.
Scientists are now trying to analyze the mechanism behind it, but no doubt the video has stunned the space community.
The video shows: “A huge chunk of the sun has broken away from its surface and is circling its north pole like a whirlpool of strong winds.”
In her tweet, Tamitha Skov wrote: “Talk about polar vortices! Material from a northern prominence has just separated from the main filament and is now circulating in a massive polar vortex around our star’s north pole. The implications for understanding the Sun’s atmospheric dynamics above 55° here cannot be overstated!”
In a subsequent tweet, she wrote: “Further observations of the #SolarPolarVortex show that it took material about 8 hours to orbit the pole to about 60 degrees latitude. That means an upper bound on the horizontal wind speed estimate for this event is 96 kilometers per second or 60 miles per second!”
She even posted a YouTube video explaining the special segment on vortex observation.
Scott McIntosh, a solar physicist and associate director of the National Center for Atmospheric Research in Boulder, Colorado, told Space.com “Though he’s never seen such a vortex, something strange happens at the Sun’s 55th parallel with clockwork regularity once every solar cycle, the 11-year period marked by an ebb and flow in the production of sunspots and flares .”
“The ‘hedge in the solar plasma’ appears every 11 years at exactly the 55th parallel around the polar crowns of the sun.”
“Once every solar cycle, it forms at the 55th parallel and begins marching toward the sun’s poles. It’s very curious. There’s a big why question. Why does it move towards the pole only once and then disappear and then magically come back to the same region three or four years later?”
Space scientists are now analyzing the strange event to gather more detail and present a clearer picture.
