Explanation:
What's happened to the Moon?  
  
  
Nothing, although from some locations, February's full moon,   
which occurred about two weeks ago, appeared   
strangely distorted as it rose.    
  
  
Visible in particular was a   
curiously   
inverted image section pinched off   
near the horizon,   
an effect dubbed the Etruscan vase by the pioneering science fiction writer   
Jules Verne for its familiar  
shape.    
  
This odd moon image piece was created by moonlight   
refracting through an   
atmospheric inversion layer on   
Earth where cold air was   
trapped near the surface.  
  
The photographer also reported that, as the moon rose, a   
red rim was faintly   
visible on the lower part of the moon, while a   
green rim appeared on the top.    
  
Similar to the Sun's famous   
green flash, these   
effects arise   
when the Earth's atmosphere acts like a   
prism, sending different colors of light on slightly   
different paths.    
  
The above image mosaic has been   
horizontally compressed by computer   
to fit a standard screen.
