These incredible rainbow clouds were observed and photographed by Patricia A Hoffman and – two followers of this blog – on October 12, 2015.
These rare iridescent clouds were photographed from Route 20 in Upstate NY. Have you ever seen something like this?
Iridescent clouds – clouds with rainbow colors – happen when especially tiny water droplets or small ice crystals individually scatter light.
Lately a strange rainbow cloud appeared over Costa Rica.
