Explanation:
It has been a good week for auroras.
Earlier this month active sunspot
region
2158 rotated into view and unleashed a series of
flares and plasma ejections
into the Solar System during its journey across the Sun's disk.
In particular, a pair of
Coronal Mass Ejections
(CMEs)
impacted
the Earth's
magnetosphere
toward the end of last week, creating the most intense
geomagnetic storm so
far this year.
Although power outages were feared by some, the most dramatic effects of these
impacting
plasma clouds were auroras seen as far south as
Wisconsin, USA.
In the featured
image taken last Friday night, rays and sheets of multicolored auroras were captured
over
Acadia National Park,
in
Maine,
USA.
Since another CME plasma cloud is currently approaching the Earth, tonight offers
another good chance to see an impressive auroral display.
