Aurora

Here's a particularly great picture of the aurorea borealis I was sending to friend LC, then decided to share with everybody.

Same viewing tips as always:

• View on as big a screen as possible (although small high-resolution screens may be better than large low-resolution ones).
  
• After getting the image displayed, click on it to switch to a black background, which is generally better for viewing and seems to be preferred by the photographer comments I've read.
