Description

THE SUN IS STILL BLANK: For the fourth day in a row, the face of the sun is blank--no sunspots. As the face of the sun grows quiet, attention is turning to the edge of the sun. The spotless sun put out a large, fast moving prominence. Prominences are filaments of magnetism filled with glowing-hot plasma. They attract attention when they grow large and hang out over the edge of the solar disk. Even when sunspots vanish, magnetic filaments are known to criss-cross the solar disk. Sometimes they collapse and hit the stellar surface, igniting explosions called Hyder Flares. You should expect to see more of these structures as sunspots fade away. Solar Minimum is not boring ... only different. http://spaceweather.com/ http://www.solarham.net/ These images were taken by the Helioviewer.org and SDO. http://helioviewer.org/ http://sdo.gsfc.nasa.gov/ Music credit: A Darker Heart by Audionautix is licensed under a Creative Commons Attribution licence (https://creativecommons.org/licenses/by/4.0/) Artist: http://audionautix.com/
