Northern lights are rarely seen in Helsinki, but the night before Monday the city was delayed.
Lucky was also Jere Huttunen, who heard from her friend that northern lights might be visible in the night sky.
On the night between Sunday and Monday, Huttunen headed to Mustikkamaa beach with his cameras.
Huttunen, who enjoys photographing nature and especially space, is used to night photography trips, and around midnight he managed to capture the northern lights above Kalasatama.
The solar wind is now fast, and the northern lights are more likely to appear in the Helsinki sky than usual for the first part of the week.
After Wednesday, the solar wind is forecast to slow to a more normal level.
"At least the next two nights are still good northern lights," says Tiera Laitinen, a researcher at the Finnish Meteorological Institute.
The best time to spot the northern lights is around midnight.
According to Laitinen, when choosing an observation site, it is worth paying attention to two factors: light and air direction.
"The most important thing is to find a dark place where there is not so much stray and wasted light."
In general, Helsinki is used to the fact that the darkest sky is found in the south above the sea.
However, those looking for northern lights should turn their gaze especially to the northern sky, Laitinen suggests.
You can search for dark places, for example, with the help of the Astronomical Society's Ursa Dark Sky website.
In Lapland, on the other hand, the northern lights have been easy to spot last day.
