!!火星可见的超大黑子来了
HERE COMES THE MARTIAN SUNSPOT:
A sunspot so big it is visible from Mars (Perseverence saw it last week) is turning toward Earth today. NASA's Solar Dynamics Observatory is watching it emerge over the sun's eastern limb
NOAA has designated this sunspot AR3576. It has half-a-dozen dark cores and a strange tail more than 5 times longer than Earth. If you have eclipse glasses, put them on and look at the sun. You can see this behemoth without magnification.
