Visibility II / V
The first northern lights of the season, for my part, were photographed in Solvalla, Espoo. The shooting started at around 11:17 pm, when the slightly more active period seemed to be coming to an end, and at 00:53, at the beginning of a more active session, the camera battery was running low. The balance 330 shots with 15-second exposures, a video of which is attached. For the first time, a battery-operated lens heater was also included, without which shooting would have stopped after just a few pictures, as the air cooled to +2 C and the relative humidity was exactly 100%. However, the fogs remained on the son of the valley and there were good unobstructed views to the north from the top of the ski hill.
