Visibility V / V
We were on our way home from a two-week trip to the north, when the sky had been cloudy until now. Ruska was incredible, but I missed the northern lights. Finally, the wish came true in Ylitornio by the Iso-Vietonen lake far beyond expectations. The fires started as soon as it got dark and I got to the beach at ten with my camera and tripod. At the western edge of the active aurora borealis, a rather stable arc or ray of red lilac rose almost to the sky while the rest of the arc was blowing green.
I saw on the Northern Lights watchers page that many others were also wondering what it was. Only at the end of the night and after midnight, high purple rays and multi-colored rays, pink lower edges of the aurora borealis and finally a multi-colored corona extending to the zenith appeared elsewhere. I thought that the SAR arch is there on the western edge, which I have tried unsuccessfully to catch before, but Emma Bruus suggested that it might be STEVE after all and urged me to post pictures here.
It was a pity when I couldn't get the longest arch photographed in one piece at night, I would quickly snap these when the fluttering northern lights took the attention elsewhere. Emma thought about the color when my picture was so purple. It might also be partially a color temperature thing. When I always take raw photos and usually the color temperature is later adjusted somewhere around 4000, at most 4500, my eye just likes a slightly bluer color temperature and then also the possible horizon yellowing light pollution looks more unnoticeable.
I've noticed that many people post yellowish night photos, I've already thought that maybe the camera's white balance is stuck on daylight settings or it's on some kind of automatic. That's when reds look redder. Because of thinking about the color issue, I adjusted the first image to 4500, then 6000 and then 7000, so that effect on the color comes out better. Finally, one more thing that I discussed with Pirjo Pike Koske, he brought up whether there were also the so-called black auroras and we thought about what their definition was. The last aurora borealis image is for that idea, a black cat inside a heart ring, quite clearly. The night was wonderful and it's always interesting if there's something to think about and give it to the wiser ones. That's where you learn yourself. Thanks to Emma and Pike for the discussions!
