Before my rush to work this morning, I was at the gas pump enjoying a splendid view of New England Fall foliage with a waning gibbous moon suspended low in the sky. The declination of the Moon was such that I could adjust my line of sight so that the Moon appeared just above the top the gas pump. Over the next minute or so, standing very still, I watched the moon sink below my artifical horizon. By adjusting my line of sight, I watched the moon set several times. A simple, yet elegant reminder that we're standing on a rapidly spinning globe and that the seemingly still astronomical sky is actually marching right along at quite a good clip.
