And to think I almost didn't leave my house for this one. This was unique in that the entire sky did not light up with color; only select areas on certain clouds did. Then even more interesting was the afterglow. I kept taking photos long after the burst had faded because I still noticed some plum to even mauve hues that even now I am not sure if they were still from the sun or from light pollution. Future time lapses should help to determine if this odd coloring is natural or unnatural some 45 minutes after sunset proper.
