(WEATHER.COM) 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. The agency says it could even be larger than six times the diameter of Earth “since the spot lies on a sphere not a flat disk.”
