We've had an amazing run of aurora--eight nights in a row, which is the longest stretch I can remember in years when we've also had clear skies for that long.  Last night the forecasts looked like that run was going to be over, so I didn't prepare for another night of shooting.  Of course, when I woke up at 1 am and looked out the window, there she was!   Not very intense at all, but just enough time to get dressed and outside to grab a couple of shots before it ended.
