Was taking a walk on the beach near Johnsons Point, Antigua. I noticed a shooting star in the sky which sent my attention to the sky where I saw this flashing light. At first I thought it was an airplane or satellite, but once it did not move for more than a few minutes, it became more suspicious. The sighting took place on the south part of the island looking south over the open ocean. The light appeared around 30-40 degrees above the horizon.
