Yes...more or less...A Full Moon is a very precisely timed phenomenon. No two people separated by more than a few HUNDRED miles will see exactly the same phase of illumination to within a fraction of a percent of full illumination. On a given night, observers in different time zones will see different Full Moons in detail, but to the naked eye they may look very nearly the same. That's because 8:00PM local time in one time zone does not show the same sky as 8:00PM in some other time zone. If two observers simultaneously looked at the Full Moon from different places on the Earth, they will see the same phase, though it may be changed slightly (3 degrees) by a parallax effect if they are far apart. If a Full Moon is scheduled for 12:00 Universal Time, and observers look at the Moon from different time zones, but at 12:00 UT, they will see the same lunar phase.
