Explanation:
The past week brought some spectacular aurora to northern skies.
These
aurorae were caused by a large interplanetary shock wave that
exploded from the Sun on April 4.
When the shock wave reached the Earth on April 6,
the resulting aurora
could be seen in clear skies as far south as
North Carolina.
As the
aurorae occurred high in the
Earth's atmosphere,
they were accompanied by an
unusual alignment of planets
far in the background.
Pictured above that night, an unusual
multicolored auroral display
graced the skies above the domes of the
Brno Observatory in the
Czech Republic.
