Point Loma,Ca, Daughter and I was standing on our balcony, when a white object appeared out over ocean. We first thought it was a helicopter, but it stayed in one spot. We watched it, and it seemed to be watching us. Someone knocked on our door, I turned to door, turned back to object. Then it suddenly moved quickly to right, then sharply turned to left and disappeared out over ocean. It seems that SanDiego, and especially, Point Loma was very active at that time. Some of my tennants were walking the next evening, and said a bright light was following,and they said that they ran back to apartment , and it stopped at the door when they entered the building. They did not know of our experience the afternoon before.
