Pekka Kokko, Kajaanin planeetta

In the evening, a message came from the children that the northern lights were visible in the sky. I felt a crack in the curtain, but I didn't see anything. Evening then the wife noticed a look at the zenith! The picture is from a meteor camera. There would be a lot of other handsome pictures, but this will replace them as well. Also included is an all-night show, the moon's 22-degree ring.
