Explanation:
What's happening above that city?
The city is
Winnipeg,
Canada, and the phenomenon is
aurora.
These past few months have been active ones for our
Sun, producing several
coronal mass ejections (CMEs) of
particles that have swept past our
Earth and caused many
spectacular auroras.
Specifically in this case, a
CME that occurred on October 9
impacted the Earth on October 11 and 12, causing nearly 12
hours of auroras.
The
above-pictured aurora had to be very bright to be seen
over the lights of Winnipeg, the city well below and in front of the
cascading atmospheric airglow.
Lights reflecting off of a slight
haze cause an unrelated glow that emanates
from some of the buildings.
