Dragon Aurora over Norway
Explanation: What's that in the sky? An aurora. A large
coronal hole opened last month, a few days before this image was taken, throwing a cloud of fast moving
electrons,
protons, and
ions toward the
Earth. Some of this cloud impacted our
Earth's magnetosphere and resulted in
spectacular auroras being seen at high northern latitudes. Featured here is a particularly photogenic
auroral curtain captured above
Tromsø Norway. To the astrophotographer, this
shimmering green glow of recombining atmospheric
oxygen appeared as a large
dragon, but feel free to
share what it
looks like to you. Although now past
Solar Maximum, our
Sun continues to
show occasional activity creating
impressive auroras on Earth
visible even last week.
