Notes:  The CME had come and gone, but it was a clear night. We were watching the Ace Solar Wind showing a steady BZ of -3. The skies were clear - we decided to go take a look. We could barely discern lightness to the north with a darker area underneath down to the horizon. We thought there might be an auroral bow. We set up the camera - took a shot - and said WOW. Ten minutes later we were able to visually discern the arc shown in this image.
