As of Dec 1, the Orion module has officially started its return journey after a burn that will send it around the moon once more and back on track to Earth. That means you can get ready to observe it heading towards us, starting on Dec 6: Dec 6th: Orion will be at ~15.5 mag, just bright enough to be observed with an eVscope. However, it will only be 10 degrees away from the full moon, so it is still difficult to observe. Dec 7th: Orion will be at ~15.4 mag, but farther away from the moon at 34 degrees separation. Dec 8th: Orion will be at ~15.2 mag and 36 degrees from the moon. Dec 11th: Splashdown!

No more Iridium flares. The last of the first batch of satellites fell down a few years ago and the new ones don't do the thing.
It's a bummer. It was fun to do a magical hand wave when a flare was going to happen. Impressed the hell out of some folks more than once. Sort of a Connecticut Yankee in King Arthur's Court thing.
Alexander von Humboldt observed the phenomenon in 1799 while looking at stars with the naked eye, but thought it was a real movement of the stars. Thus, he named them "Sternschwanken", meaning "swinging stars". It was not until 1857 that G. Schweitzer (Schweitzer, 1857), an early German psychologist, discovered that it was a subjective phenomenon. Many sightings of UFOs have been attributed to the autokinetic effect when looking at stars or planets.
Very cool you mentioned Twain.
