Visibility III / V
The camera was shooting in a timelapse position with northern lights heading north. At the same time, this meteor had been recorded, which, judging from the direction of arrival, belonged to the Perseid star flock.
The same meteor is apparently also present in this observation: http://www.taivaanvahti.fi/observations/show/41113 .
It is special that in my own pictures (unlike Jouni Hovi's observation) the meteor only appears in one picture. The camera was taking pictures with a 16-second exposure. There was a 4 second pause between images.
To justify a closer look at the metadata, this image has been exposed between 01:30:58 and 01:31:14.
