Explanation:
One of the most active sunspot groups in years is currently crossing the Sun.
AR 1302 first
came around the Sun's edge
last week and is so large it can be
seen without a
telescope.
Coronal Mass Ejections from AR 1302 have already caused
strong geomagnetic storms including notable aurora activity around
both of Earth's poles.
Pictured above, plasma was left magnetically hanging above the Sun's surface after
AR 1302 emitted an
X-class solar flare
last Thursday.
Earth is illustrated in the inset for a size comparison.
Although another
X-class flare was emitted
on Saturday, no flares from AR 1302 have been aimed directly at the Earth, as yet.
The AR
1302 sunspot group will continue to evolve but likely remain visible on the Sun
for the next week.
