Why bring up, going into August,
that this year has 13 full moons?

Because August has two full moons,
the first on 1 August,
the second on 30 August.

And the second of those full moons is ... you guessed it ...
a BLUE MOON.

(Maybe this belongs with the Mother of all BS?)

There are 13 every year, no? 28x13=364?

Apparantly 'Blue Moon' has 'traditionally' been attributed to the Maine Farmer's Almanac.
Blue Moon - Wikipedia

The term has traditionally, in the Maine Farmer's Almanac, referred to an "extra" full moon, where a year which usually has 12 full moons has 13 instead. The "blue moon" reference is applied to the third full moon in a season with four full moons,[2] thus correcting the timing of the last month of a season that would have otherwise been expected too early. This happens every two to three years (seven times in the Metonic cycle of 19 years).[3] The author of a March 1946 article in Sky & Telescope attempted to decipher the traditional practice of the editors of the Maine Farmers' Almanac by examining old issues of the almanac. Without enough almanacs to see the correct pattern, he conjectured the wrong rule for 'blue moons', which led to the modern colloquial misunderstanding that a blue moon is a second full moon in a single solar calendar month, with no link to the order it occurs in a season.

No.
365.25 / 29.54 = 12.37. So 13 about every third year (7 years in 19, to be nearly exact).

Bob L WINS THE EXACT TROPHY. but not all months have the same number of days so results may vary.

And it depends on for how long you consider the moon to be full. All day? Only when it's above your horizon? At the instant that it is exactly opposite the sun?

And, depending on that, where you are. Two observers on opposite sites of the International Date line may be seeing the moon on different days. Does it depend on what day it is on the moon?

I would suggest that the time zone for the moon is UTC (Universal Coordinated Time) Also equivalent to GMT.

If you were on a ship that went various warp speed, in very complicated ways, time would be displaced and meaningless.
Terrestrials would seem to you to rapidly age.

And what is more,
the August 1 full moon is known as
the Sturgeon Moon, amongst other names.

I was thrilled with the beautiful 'super moon' that rose above the fields opposite our house two nights ago. What an enormous orange disc glowing in the dark! But the cloud cover has been too persistent since, and we can't see the moon at all.

So Donuel, that picture has no identification on it of when/where it was. When was that 'blue moon'?

If it was this week it was not a 'blue moon', by definition.

If it was on 'pictures of the day' (very recently) then I think you can be certain that it was not a 'blue moon'. A blue moon is the second full moon to appear in a single calendar month. The full moon at the end of August will be a blue moon.

That picture from Sicily posted above looks like a sunrise or sunset, not any kind of moon I'm familiar with.

That's what I thought. I thought there'd been a mistake. I was in Sicily a month ago, which has absolutely nothing to do with anything!

The picture in context

Ragusa is in the south of Sicily.

So tonight the old moon will be in the new moon's arms, which is an ill omen.

We're now approaching the August blue moon, that is,
the second full moon in the month.

I wonder how much the super moon had to do with
the soaking rainstorm we're getting right now.

Not much, but you are getting what is an overflow of moisture.
Look what you started keb.
FL is at low tide right now but Georgia will be at high tide when the storm reaches the Atlantic again.

The fortunate thing about Idalia is that the storm moved so fast;
it would have been worse if
the storm had circled about in the same spot
and dropped that much more rain in one place.
