A rainbow a day …

There’s an old weather saying: ring around the sun or moon means rain soon. There’s truth to this saying, because high cirrus clouds often come before a storm.

These clouds contain millions of tiny ice crystals. The halos you see are caused by both refraction, or splitting of light, and also by reflection, or glints of light from these ice crystals.

  1. It looks like a sun halo. A halo formed when sunlight breaks into very high cloud layers that consist of ice. Often this means a change in the weather. The pictures I like very much and it is rare that you can take pictures as well. My congratulations.

    1. Quite amazing day! And a crack that leaked the rainbow with light shooting out from the rainbow was amazing. The rainbow appeared for two days like this. Hummm, I did and info “about” halos. ???
