NASA Images Massive Sunspot - Solar Flare Producing Sunspot Forming On The Sun.(PS). An enormous sunspot, six times larger than the Earth is currently forming on the Sun. NASA researchers predict that the sunspot could begin triggering powerful solar flares in a couple of days.
The enormous sunspot has been monitored by NASA’s Solar Dynamics Observatory over the last 48 hours as it has developed. SDO is permanently monitoring the Sun, one of a few spacecraft that does so.“It has grown to over six Earth diameters across, but its full extent is hard to judge since the spot lies on a sphere, not a flat disk,” said NASA spokeswoman Karen Fox, of the agency’s Goddard Space Flight Center in Greenbelt, Md.
The region where the sunspot is located “is actually a collection of dark blemishes on the surface of the sun that evolved rapidly over the last two days. Sunspots form from shifting magnetic fields at the sun’s surface, and are actually cooler than their surrounding solar material.”Read and see the full story here.
