This is the region at the center of the side of the Moon which faces the Earth. It is where the center of the official IAU lunar coordinates system is located, i.e. Longitude-0 on the lunar Equator.

It would be the ideal site to place a rectenna (receiving antenna) to receive microwave energy beamed down from Solar Power Satellites located at the Lunar L-1 Lagrange libration location between the Earth and the Moon.

It would also be the best site for an anchor point to attach a tether extending up to the Langrange L-1 libration location between the Earth and the Moon.
