A dream came true when travelling to Iceland to see the auroras and what a luck we had. Four consecutive nights with truly magical moments.
The first night movement was rather slow at the beginning but staying outside was worth as at 2am (after all the tour busses returned to the city) some vertical streaks suddenly appeared just in front of us, growing in width and starting to move slowly like a curtain in a faint wind. It lasted for almost 30 minutes while the auroras at the horizon stayed on for another 2 hours.

BTW: Can somebody can confirm that the white streaks on some of the pictures are shooting stars? Though I have only seen one with the naked eye, the photos I took in about 4 hours showed almost 20 of them. None of the pictures from the following days show a single shooting star.
