Photographer's Note

Continuing series of my roundabout series with a scene I never even dreamed about to catch.
If lightnings are tricky to catch, so are northern lights (aurora borealis).
The whole event was highly unlikely. You don't usually see these in summertime because the sky doesn't get dark in evening time when they are most likely to appear. Not to mention interfering city lights. Tampere is in southern Finland where this is not very common anyway. And solar activity that causes the phenomenon is not supposed to be very high this year.

Composed of two frames for two reasons: First the brightness difference was high so the street overexposure was inevitable. And I didn't remember how to measure exposure and focus on two different spots. Autofocus was hopeless on the sky. And there certainly wasn't time to start studying. The whole show lasted about three minutes from the moment I had the tripod ready.
Nevertheless the final picture is faithful to the original. Levels and curves adjusted. No colour changes.
18 mm at ISO 200 (exposure values for the sky part).
