Visibility II / V
Last night's aurora borealis filmed by GoPro to the statistics. Right at the beginning of the timelapse, you can see rays in the northeast and after the middle in the northwest. The timelapse was filmed around 0:30-2:30. Picture 2 shows a screenshot at about half past one and picture 3 about 2 o'clock. The clock on the camera knows what time it was, so the times are indicative. Exposures 30 seconds, ISO 1600.
