Experiment with multiple instrument places all over the earth

[ritwik06]

I want to design an experiment with multiple instruments places all over the Earth in such a way that at any time, at least one of the instruments can observe the sun. What is the maximum separation of instruments permitted?

I am really confused. Please help me with this!

Ok! the sun will be visible from one hemispher for sure, am i right. So I think it should be 1/2 the circumference of earth.
