Quiet aurora arc - 30.3.2021 at 22.49 Parainen Observation number 97255

Visibility II / V

I put those northern lights as a tag here, when they have it too. Green appeared on the camera screen when shooting, but red came as a surprise when developing images. There was a lot of red for some reason last night. But the picture also shows the zodiac light below the screens diagonally.

There came an image that should not exist. The night sky is starting to be too bright and the northern lights have hardly been like this in the south. Calm evening, the ice left earlier in the evening. But when it came to calm, I had to go with the camera to walk and watch the scenery + stars. The Milky Way still shows a particle and Andromeda hides as a lens. The yellow on the right side of the picture comes from either Uusikaupunki or maybe Olkiluoto (the distance to Uusikaupunki is about 60 km and to Olkiluoto 10 km more). Otherwise, the sky is dark there to the northwest. The darkness of Bortle 1 is there further afield at sea on the other side of Brändö, at the scene bortle 2 or bortle 3 (just on the border).

in the second picture I dug the product out of the zodiac light a little more clearly and therefore it is so powerful (adjustments made in Affinity Photon levels color channel at a time)
