What did the UFO look like, shape/size in relation to
terrestrial objects/lights/colour :
it was in a cloud and appeared to be an elongated oval of faint white light,it was irridesant.
Did the UFO do any
strange things like hover and then zoom off quickly :
it moved from left to right as I was looking at it in the same pattern for about fifteen minutes. It was larger than a helicopter and when a helicopter approached the helicopter was much clearer and more easily visible. The light suddenly vanished as the helicopter approached it.
