			What does this aurora look like to you?
While braving the cold to watch the skies above northern 
Canada 
early one morning in 2013, a most unusual aurora appeared. 
The aurora definitely appeared to be 
shaped like  something , but what?
Two ghostly possibilities recorded 
by the astrophotographer were "witch" and "goddess of dawn", 
but please 
feel free to suggest your own 
Halloween-enhanced impressions.
Regardless of fantastical 
pareidolic interpretations, 
the pictured aurora had a 
typical green 
color and was surely caused by the scientifically commonplace action of high energy particles from space interacting with 
oxygen in 
Earth's upper atmosphere. 
In the image foreground, at the bottom, is a frozen 
Alexandra Falls, while 
evergreen trees 
cross the middle.
