Visibility V / V
My aurora sighting started with corona. And now I'm not talking about that disease. I went to the yard to take a look at the cloud cover situation. In the middle sky, I noticed strange-looking clouds that resembled an aurora corona. I took the camera and took a picture of it. The "clouds" were indeed green, so it was the Northern Lights corona! I hadn't followed the northern lights, this came as a bit of a surprise. I took pictures from other parts of the sky as well, and everywhere was green. And there were also clouds, behind which the aurora borealis mostly remained at the beginning, except that Korona now happened to shine just in time due to the thinning of the cloud (picture 2).
Fortunately, the sky almost cleared up and the northern lights became properly visible. They were first concentrated in the southern hemisphere, which is unusual. The pictures showed almost only green color. There was green everywhere. The brightest shapes were really bright, and the northern lights lit up the landscape, the yard was as bright as moonlight. (The moon was not above the horizon now.) The aurora corona also came into view many times. Hoping for rare forms of aurora borealis, I took photos from all sides of the sky, even at places that looked dark, but I couldn't find anything special.
Around half past twelve, the northern lights started to dim and retreat towards the north. It was only at that point that the red color started to appear in the photographs (Figure 8). However, the camera's battery started to run out, and I didn't get many pictures of the reds anymore. I also thought the show was coming to an end, and after watching it for a while I went back inside.
Later in the night, I took another look at the situation, and I realized that there is "full noise" again, picture 1. I continued to photograph for a while, but then the clouds covered the sky, and I thought that it might be time to stop. Probably the clouds would have parted after a while, and the aurora borealis would have been enough to watch until dawn.
These were the fiercest aurora borealis of this year so far, of the ones that have happened to me.
