My news feed is all aflush with heralds of an upcoming lunar eclipse this weekend, July 4-5. "Come see the eclipse of the Buck Moon!!" they gush.

Problem is, it's a penumbral eclipse. This picture is NOT a penumbral eclipse. Come on, Mullaney! You used to write for S&T! Have some standards, man!
A penumbral lunar eclipse is when the Moon passes only through Earth's outer shadow, the penumbra (meaning before the umbra, the full shadow.) If you've ever seen one, you know you can hardly ever see one. It's so faint it is very hard to tell something - anything - is going on. I don't highlight these to the public, because if they go through the effort to see it, they will think they missed it, and it's "a total ripoff!" as one guy put it.
Here is Mr. Eclipse's diagram to let you see how little will be covered:

Oh, go out and look, but watch it when it's coming up at 8:58 pm CDT, LOW in the SE. Now THAT's worth getting out for. At that low angle, with the Saharan dust and forest fires, it's likely going to have some lovely color.
By the way (editor's note) the polling has now closed and by an overwhelming majority, the very coolest American Indian name for the July full moon is "The Thunder Moon." Full stop. In fine disputandum.
Lunar Eclipse this weekend... Ah, sort of.
