Explanation:
What's happening behind that mountain?
A convergence of variable sky spectacles.
One night in mid-September near
TromsЬ,
Norway,
high red aurora could be seen shimmering through lower green aurora
in a way that created a striking and somewhat unusual violet glow.
Suddenly, though, the sky flashed with the
brightest fireball the
astrophotographer had ever seen, as a small pebble from outer space
violently crashed into the
Earth's atmosphere.
The glow illuminated the distant mountain peak known as
Otertinden of the
Lyngen Alps.
The bright
meteor, which coincidently disappeared behind the same mountain,
was also reflected in the foreground Signalelva River.
Although you might consider yourself lucky to see
either an aurora or a bright meteor, pictures of them together
have
been
recorded
several
times
previously.
