This is last night’s afterglow following sunset over Great Cove.
As the months get colder, the sundown colors get warmer. By November, some of our afterglows will be blood red. For example , here’s a November 17, 2019, image of part of the same area:
The warmer light apparently is due to the changing rotational angle from which the sunlight passes through the sky’s color spectrum to get to us. (Brooklin, Maine)
