Read Catherine King's Crowd of Witnesses for the background to this persistent phenomenon.
(This was a point-and-click snapshot, with a Canon PowerShot A70, toward the southeast at twilight on a calm, clear, hot August day.)
(If the link doesn't work, and it doesn't right now, just scroll down the Recent Entries on the right for Crowd of Witnesses.)
