The second day of that heavy spraying,we had very rare view in the sky, called "sun halo effect" with "sun dogs"(two small rainbow "suns" on the right and left side of the sun), I've taken some pictures:

What I'm finding strange is that this kind of effect is usually visible in places where is very cold (I've just seen pictures taken on south or north pole or Alaska)-cloud has to contain ice crystals,and that day we had really warm weather 78 F,of course I realize that up there is much colder ,and I'm not sure was it natural or they sprayed something what caused that effect.
