Question about the full moon

Paul"Hungerdunger" wrote in ...

I know nothing about astronomy, but I have a dispute which someone
here might be able to settle for me:

When it's a full moon in the UK, is it also a full moon in all other parts
of the world at around the same time, or does it vary according to
latitude or longitude?

A think 'full moon' is a sort of non-scientific term.

A more precise term is opposition. That is the instant that the moon is
directly on the opposite side of the earth from the sun. Opposition is at
the same time wherever you are located on the earth.

It takes something like 30 hours for the percentage visibility to go
from 99% through 100% (full) to 99% again. So the moon will appear
full for almost everyone on the planet.

It can seem to be full for two transits on occasion. A transit to
transit is a "tidal day" of just over 24 hours and 50 or 55 minutes,
IIRC.

It takes something like 20 hours for the moon to go from 1% visibility
through new moon to 1% again.

(Or is that the times for half percentages I remember?)
