NATURES WAY......

... without a Blip again late in the day (4pm EDST), and noticed this colour in the clouds to the North from our backyard, that has to be it!!
So here we have it, and have since determined that part of the "cloud" is actually smoke from a burn off in the Mountains, and the late sun to the left, has given this colour.

Enjoy, and have a look in LARGE.
