I have not had the pleasure yet in witnessing such a spectacular phenomena…one day I will. In the meantime, for those like me who have not yet seen in person, here you go.
The last picture is a Fire Rainbow, which is the rarest of all naturally occurring atmospheric phenomena. The picture was captured on the Idaho Washington Border, the event lasted about 1 hour. Clouds have to be cirrus, at least 20,000 feet in the air, with just the right amount of ice crystals and the sun has to hit the clouds at precisely 58 degs.
Aurora Borealis (Northern Lights), Yellow Knife, Canada.
