On the Great Feast of the Trinity, the Ukrainian believers, who watched the broadcast of the solemn service from the Kiev-Pechersk Lavra, saw in the sky above the temple a bright rainbow glow around the sun - a halo. Still images of the miraculous phenomenon, captured by a video camera, appeared on the official page of the Ukrainian Orthodox Church on the facebook social network.

Halo as an optical phenomenon in the atmosphere is well known to scientists and is a secondary glow around the sun or a powerful artificial light source. It is interesting to note that On Trinity, the same radiance around the heavenly body was observed by the inhabitants of the Holy Trinity Iona Monastery in Kiev, who gathered for common prayer.
