Massive sunspot rapidly forming, solar storms possible… 45% chance of M-flares and a 15% chance of X-flares during the next 24 hours.
A giant sunspot that’s at least six times the diameter of Earth has formed on the sun in less than 48 hours, according to NASA.
Sunspots form when the sun’s magnetic fields rearrange and realign. They tend to be unstable andcan lead to solar flares.
According to a news release, scientists from NASA’s Solar Dynamics Observatory watched the sunspot rapidly grow on February 19 and 20.
A colossal sunspot on the surface of the sun is large enough to swallow six Earths whole, and could trigger solar flares this week, NASA scientists say.
The giant sunspot was captured on camera by NASA’s Solar Dynamics Observatory as it swelled to enormous proportions over the 48 hours spanning Tuesday and Wednesday (Feb. 19 and 20). SDO is one of several spacecraft that constantly monitor the sun’s space weather environment.
“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,” wrote NASA spokeswoman Karen Fox, of the agency’s Goddard Space Flight Center in Greenbelt, Md., in an image description.
CHANCE OF FLARES: New sunspot AR1678 has developed a delta-class magnetic field that harbors energy for strong explosions. NOAA forecasters estimate a 45% chance of M-flares and a 15% chance of X-flares during the next 24 hours. Solar flare alerts: text, voice.
