Around 10 am (St. Petersburg). I decided to watch the clouds with binoculars. And after a few minutes I saw the flight of 2 balls at a short distance from each other.
Against the background of a white cloud, they were clearly visible. The sun was behind. The balls can be one to two meters in diameter. When they went beyond the border of the clouds, they became hardly distinguishable against the background of the blue sky. Glittered only silver.
I already thought that I lost them when I saw that 2 more flew up the same size. They joined in a group and flew back a little. Again the clouds were clearly visible in the background. Then the clouds flew out of the border and I completely lost sight of them.
I began to examine the horizon and to the right, somewhere 45 degrees, I saw this object. It seemed to me that the balls were waiting for him or accompanied. It is located at the same height as I drew vertically. And he moved away from me straight up. Moved: turn left-straight-turn right.
Ie it was turned to me by the sides and back. With each turn, it went further and further. As if floating. At first I thought it was spinning, but no.
The color is dark, almost black. When the back was facing me, I saw a cross-section of the sky, that is, it shone from the middle to the bottom as I drew.
