Visibility II / V
On the day of work, walking from one office to another and the sun shining from behind, I first noticed a piece of horizon ring in the dim cloud. Turning towards the sun, a partial 22-degree ring and side suns were visible. Luckily there was no rushing, and I was able to stop taking pictures of what I now got on my cell phone. I also took a clip of the video following the horizon map, but the file is too big. Later, a piece of the lower edge of the 22-degree ring was still visible.
The pictures may show more, or just tense cloud shapes. I leave the interpretation to those who know it.
