Explanation:
This sky looked delicious.
Double auroral ovals were captured above the town lights
of
жstersund,
Sweden, last week.
Pictured above, the green ovals occurred lower to the ground than
violet
aurora rays above, making the whole display look a bit like a
cupcake.
To top it off, far in the distance, the
central band or our
Milky Way Galaxy
slants down from the upper left.
The auroras were caused by our Sun ejecting
plasma
clouds into the Solar System just a few days before, ionized particles that
subsequently impacted the
magnetosphere of the Earth.
Aurora
displays may continue this week as an
active sunspot group rotated into view just a few days
ago.
