It was more or less 9 PM. I was on the computer at my home on the suburbs of Ponta Delgada in the island of S���o Miguel (Azores).My mother went to open the door of our house when she noticed a strong light over a mount some miles away. Immediatly she called me and I went to see it.At first I thought it was an emergency flash light but then it started moving in different directions until it disapeared during few seconds. Then it appeared again for a little bit and then disappeared completely.The object was kind of oval shape, very bright white light.
