The following letter came to the newspaper 's editorial office:

In connection with the published article in the newspaper "Trud", we wanted to be of some help to you. We (i.e. my father, Vladimir Stepanovich Tsiolko, and I, his daughter) this phenomenon has been observed. It was January 29 at 2-15 am, because we live on the 5th floor it was visible well.

This phenomenon was similar to a curved arc and rays of colored pink, light-light purple radiated from it, and in the middle of the arc there was a light blue color on the sides, and a thin black stripe in the middle. There was light on the pillars and from the light rose up like a rainbow to this arc and was illuminated like a searchlight.

My father does not sleep, he has insomnia, so he saw it well and showed it, and this phenomenon is not in the sky. We would like to know what it is.
