The aurora event I photographed from Flakstad, I posted an image from this event last week, did not last for long. I managed to get a couple of shots before it faded. And this is one of the images, with the Big Dipper (US), or Plough (UK), in the background.
And about a couple of hours after the sunset shot the aurora appeared through the thin cloud cover. It lasted for a short while before disappearing again, but I got a couple of nice shots.
