Is there a full moon all over the world?

If you're both viewing the stars in the Northern Hemisphere, you'll both see the same ones... if you know your stars.
However, if one of you were in the Northern... the other in the Southern Hemispheres - definitely different stars... if your know your stars.
The moon has been covered!
But, I often see the moon in daytime hours, mostly on clear sky days without any clouds.

Last January I was in Paris and I saw the full moon every night for an entire week. I could also see the dark side of the moon. But that's because Ugly Naked Guy across the way from my hotel room would never close his drapes.

I love all of you Fodorites. I thought there were different stars depending on where you are. I know a penpal in Australia who sees Southern Cross and I have never seen it and I am in the North America. It is so hard to imagine that a person standing with a kangaroo will see the same sort of moon that a person standing with a yak would see.
I should have listened in school - I only remember my teacher rolling around with a cantalope, an orange and an apple - it was hard to imagine the universe that way.
Thank you!!!
Oh so it comes down to this - two people in the Northern Hemisphere will see the same type of moon - right? Don't be mad at me.

Tibetans may have little choice of animal company, but personally I try to avoid the company of kangaroos. This whole thread is giving me a headache; however, I can advise that the technology required to reverse the image of the moon was developed from earlier experiments designed to make water rotate in the reverse direction as it exits the bathtub or toilet. More than that I'm not authorised to disclose.

Hi peeky,

Right.
Two people in different hemispheres will also see the same moon. However, the image of the "man in the moon" will not be the same.
Viewing the stars from the different hemispheres yields different constellation groups, eg, Southern Cross vs North Star.

OK thank you. So the man in the moon is on his head in the Southern hemisphere -who would have thought. Now is the moon made of green cheese - just joking with ya - and why would it be green cheese - you would think it would be brie.

The phase of the moon is only marginally dependent upon the location of an Earth-based viewer. The difference is so small as to be non-existent for all practical purposes.
The reason that moonrise and moonset times are harder to determine than their solar equivalents is that the lunar orbital orientation is fixed with respect to the ecliptic, rather than with respect to the Earth.

Interesting question: is the phase of the moon represented by how much of the area facing an observer is illuminated, or where the terminator is (which is the same for any observer)?
I'm in the latter camp, <i>i.e.</i>, everyone sees the same phase regardless of location.

Are there southern lights towards the south pole, as there are northern lights to the north? Maybe some day I'll get lucky and get to see the northern lights! That's on my list of things to do, but I'm not willing to go too far north in the dead of winter. They are going to have to come to me!

Just to add to the havoc here. Yes, you'll both see the full moon on the same day (unless it's overcast).
But, you may not both be able to see it at exactly the same time. Check the moonrise and set times for that day in each location, then consider that in city areas it will probably be visible for less time than that due to its being obscured by tall buildings.

Yes, they're called <i>aurora australis</i>.
You don't have to look up moonrise times. At fullness, the moon rises at sundown and sets at dawn, because it's on the opposite side of the earth from the sun. If the sky is dark where both observers are (they might be as much as 180° - or even a little more - of longitude apart), they will be able to see the full moon simultaneously.
