Details:
Around two hours before the sunset on September 24, 2019 the horizon (images 3 and 4) looked very weird indeed. In fact it was not even the horizon, but rather a false horizon. Fata Brumosa, a Fata Morgana of the sea surface was clearly present. In one part of the horizon (image 3) there was a sparkling wall and a top of this wall there was a small boat. Other parts of the horizon were curved (image 4). I was thinking about Marines of old who used sextants to navigate. With such horizon it would have been all but impossible to measure an angular distance between the stars and the horizon. The sun was nearing that strange horizon and I remembered Sir Shackleton's description of the sun he saw in Antarctica during polar night:
" Just before noon to-day (July 26) the top of the sun appeared by refraction for one minute, seventy-nine days after our last sunset. A few minutes earlier a small patch of the sun had been thrown up on one of the black streaks above".
Now I was looking at the black streaks (image 3) and the images of the miraged sun above and below it. It was Novaya Zemlya effect, usually observed only in Polar regions. In my situation the last light of the miraged sun disappeared 6 minutes after the predicted sunset time. A few times it appeared that theimages of the miraged sun were gone, but then they were coming back. The refraction was strong enough to see the mirage for much longer, but the hazy atmosphere eventually has won and the wondrous mirage was gone. Here's the video of the sunset I filmed https://www.youtube.com/watch?v=3w-TFGMSpQQ&t=184s and here's the video of the horizon before the sunset https://www.youtube.com/watch?v=7dJQGK2y1Mw
