Totally clear sky today. I saw the sliver of the moon up high in the blue sky a few times. And when I left work just after sunset it was a very pretty time of day/night as everything darkened. I haven't been out at night much lately but now, for obvious seasonal reasons (axial tilt!) I am!
Also, the local street lamps got LEDified just in the last couple years and those are pretty distinctly yellow LEDs. The bigger roads have much whiter LED lamps. Well, and there were (and I think might still be a few left) the defective lamps on the highway with the dead phosphor that were just straight up purple!
