Tales of Unusual, Bizarre, and Other Hard to Explain Observations

Checked out in a hurry, just before the Covid shutdown. Not really science, mostly a collection of unreplicated anecdotes about observations near the edge of human perception. Now that we can observe the entire sky with CCD cameras, deep memories, and lots of computation, humans can focus on hypotheses based on shared data.

One interesting factoid is that Ganymede may be visible to some unassisted eyes in optimal conditions. The problem is that Jupiter is vastly brighter than Ganymede. This article describes the opportunities and difficulties:

It does not cite other papers describe plausible observations, nor do any followup papers cite this one. Reading between the lines, there have been and won't be trustworthy naked eye observations of Jupiter's moons from the Earth's surface. So, this factoid, and this book, is more about the psychology of fallibility and trust.
