You are located in New York, NY, United States. Your friend is located in Panama City, Panama. You see a waning gibbous in your clear night sky. What phase, if any, will your friend see if the night sky in Panama City is also clear?
The same side that you see in one place of the continent at night, you will also see in other place on earth, regardless of the hemisphere. There is however a slight difference, but not ecognizable to the human eye thus Waning Gibbous will also be seen everywhere else in the night sky that night.
