Visibility III / V
Veikko Mäkelä put a message in the middle of the night clouds in one of the countries, something would be visible in the northern direction. I was just going to see the sky of Midsummer myself, and quite accurately I was able to giggle clouds that still stand out quite poorly. I could see a wave-like formation, however, then began to stand out with clear belts, albeit a little hazy.
Without a quarter, however, these began to brighten and were already quite noticeable. Belts, slightly wavy and gauze. And Capella, which can be seen in the pictures, stood out from the sky of Midsummer with the naked eye.
After one, the clouds began to dim.
Figure 1 is treated with a blurred mask ("fogged") to better distinguish the details of the clouds.
