Explanation:
This almost otherworldly
display of northern lights was captured in
clear skies during the early hours of March 31 from
44 degrees north latitude, planet Earth.
In a five second exposure the scene looks north from
Martinique Beach Provincial Park in Nova Scotia, Canada.
Stars of the W-shaped constellation Cassiopeia
shine well above the horizon,
through
the red tint
of the
higher altitude auroral glow.
Auroral activity was anticipated by skywatchers
alerted to the possibility of
stormy
space weather
by
Sun-staring
spacecraft.
The predicted geomagnetic storm was sparked as a
coronal mass ejection, launched from
prolific
solar active region 2975, impacted our
fair
planet's magnetosphere.
