Visibility II / V

Antti Kirkkala, Ursa (Etelä-Suomi)

Northern lights were visible from Tapiola's Otsonkallio to the north and northwest, which seemed to be seen from the unusually strong southern parts of the country. The last time I had seen such things was in Kuusamo at the beginning of the millennium. According to the Finnish Meteorological Institute, the magnetic activity at the time of imaging was 1.52 nT / s.
