Which coordinate system would be most useful for two observers 0one in Michigan and one in Florida who want to observe the same astronomical object and discuss their observations over the phone as t?

Answer 1

The widely accepted celestial coordinate system of Right Ascensions and Declinations

would be most useful to them, if they both knew their way around with it, and at least

one of them knew the celestial coordinates of the object.

Answer 2

Using equatorial coordinates would be most useful for the two observers, as this system is based on the Earth's equator and celestial sphere. By referencing the object's position in right ascension and declination, both observers can easily locate the object regardless of their respective locations. It would facilitate clear communication and comparison of observations between the two observers.
