Auroras

Solar activity often leads to Auroras so this may be of interest.

The sunspot number soared this weekend when new sunspot 652 emerged over
the sun's eastern limb. This active region is big, about the size of the
planet Jupiter, and easily seen from Earth. Warning: Don't look directly
at the sun; doing that could blind you. Instead, try the safe solar
observing techniques described at spaceweather.com.

With the emergence of sunspot 652, there are now two regions on the sun
that pose a threat for strong solar flares (sunspot 649 is the other
one).
High levels of solar activity are possible this week.
