Aurora

September 28, 2011

The first two shots are about a minute apart. ¬†They’re 60 second exposures (it takes another 60 seconds to empty the buffer onto the card). If you download them and toggle back and forth you can get an idea of the movement of the auroral structures over time. You can also see the big dipper moving.
