At any instant, Earth's SUB-LUNAR POINT is the point on our globe "directly under the Moon." Expressed another way, it is "where the Moon appears directly overhead." Always changing, this point circles the globe once a day. In addition, each month it migrates north and south over the equator as the Moon progresses in its irregular orbit. Plus, at times it can move beyond the tropics, due to the inclination of the Moon's orbit. In the image above the sub-lunar point is plotted at the instant that this page loaded.
