Description:
"Sometimes, after your eyes adapt to the dark, a spectacular sky
appears. Such was the case earlier this month when one of the largest
auroral displays in recent years appeared over northern locations like
the border between Norway and Russia.
Pictured in the above time-lapse movie, auroras flow over snow covered
landscapes, trees, clouds, mountains and lakes found near Kirkenes,
Norway.
Many times the auroras are green, as high energy particles strike the
Earth's atmosphere, causing the air to glow as electrons recombine with
their oxygen hosts. Other colors are occasionally noticeable as
atmospheric nitrogen also becomes affected.
In later sequences the Moon and rising stars are also visible. With the
Sun expected to become ever more active over the next few years, there
may be many opportunities to see similarly spectacular auroras
personally, even from areas much closer to the equator.
