At least 5 lightning strikes seen - 17.10.2022 at 00.12 - 17.10.2022 at 02.05 Virolahti Observation number 110048

Visibility III / V

I went to receive the storm in Virolahti - I had drawn lots between Emäsalo and Virolahti and actually after this I am satisfied that I chose Virolahti, there when the storm no longer hit with such a strong force as in the west.
However, the lightning was quite small, I saw about six flashes in the clouds, I didn't hear a rumble either (the wind and the sea were roaring so loudly). In the first picture, storm clouds flying in the wind. I got a picture of one of the bald eagles (lower picture).

      Kalevantuli on epämääräinen välähdys, josta ei kuulu jyrinää ja joka on yleensä etäällä taivaanrannan tuntumassa. Kalevantuli on maasalaman tai pilvisalaman heijastusta.

      Erotuksena kalevantuleen elosalamassa erottuu salaman viivamainen rakenne. Sekä kalevantuli että elosalama ovat molemmat salamointia, joka tapahtuu yleensä yli 20 km etäisyydellä havaitsijasta, mistä johtuen jyrinää ei kuulla.
