Initial data

In the newspaper "Trud" dated January 30, 1985, I read an article "Exactly at 4.10" and decided to write my observations.
It was January 29 at 14-20 (January 30 at 15 o'clock was the same). I went to the window and noticed the sun. It was, or seemed to be, much larger than usual and the rays radiate far around it. Then it became normal round and began to change colors periodically. Yellow, then green, then pink. In general, it was painted with all the colors of the rainbow. In the rainbow, these colors are pale, vague, but here every color is bright.
Maybe it's not new, but I've seen it for the first time.
Hypotheses
Halo
Halo usually appears around the Sun or moon, sometimes around other powerful light sources such as street lights. There are many types of halos, but they are mostly caused by ice crystals in Cirrus clouds at a height of 5-10 km in the upper troposphere. The form of the observed halo depends on the shape and arrangement of crystals. Reflected and refracted by the ice crystals, the light often turns into a spectrum, which makes halo look like a rainbow, but a halo in low light has a low chroma, which is associated with the peculiarities of twilight vision.
