I've included some shots from the afterglow all the way through the twilight's last gleaming. I shot these on the evening of December 21, 2019. The sunset started out looking like it would have potential, then the sky turned all blue for some time, then suddenly - almost 20 minutes after the sun had set - some orange/pink/red hues came in from the north and worked their way south. Shot with a Canon 6D and Canon 17-40mm f/4L lens.
