Rule reference?

However, a full moon CAN occur without a lunar eclipse. And there was a full moon before and after the event.

Of course...just like a solar eclipse can only happen during a new moon.

It's possible (I'm not going to look it up) that under a very strict definition, a "full moon" lasts only an instant. The moon would be a waxing gibbous the instant earlier and a waning gibbous an instant after.

Redundant. Lunar eclipse will suffice.

Correct. It happens quite often. Ten to thirteen times a year, usually eleven per year.

As well as during the event. The moon was still in its full phase during the entire eclipse.

Correct.

OK. Maybe redundant was the wrong word. "With the full moon & lunar eclipse" is kind of like saying, "I've got a five cent nickel (referring to 21st century American coins). I'm sure that mbyron will be along shortly to tell us what was wrong, if anything, with the statement, "With the full moon & lunar eclipse".

Yes. However a specific phase, like full, first quarter, last quarter, or new, is often considered to last one day. Cool reference to waxing gibbous, and waning gibbous. I wish more people were as scientifically literate.

Sounds good.

Right. And Billy said that "full moon and lunar eclipse" was redundant. He meant "wordy." Just saying "lunar eclipse" would be sufficient.

No it's not. Neither a lunar eclipse nor a full moon is a set, so neither can be a subset of the other. :p

Perhaps you mean that the set of lunar eclipses is a proper subset of the set of full moons? It makes more sense to say this without set theory, IMO.

I think I'm going to have a great game tonight. This thread is making me a better official. :D

I would have never, in a million years, guessed that this would have turned into a cooking forum. Never. I would have bet my house on it.

I just hope he doesn't end up mooning the crowd, which would eclipse all of his prior embarrassments in life.
