It was a Bright Red Light as big as a Tennis Ball in the sky.When i was looking at the constilation of the Big Bear, i suddenly saw a big bright red light the size of a tennis ball coming out of the dark sky from the south-west it continued to the north-west in a parabollic shaped path then it disappeared behind the buildings. Suddennly, the same shape came back! It was as if it was returning back but not on the same path but a slightly differenet one from the north to south-west. Then suddenly it came back again! The same bright red light from the south-west to the north then it vanished behind the buildings. The light was substantially fast as if you put your hand in the sky and then quickly move it across. Moreover, the light wasn't sharp. It was blurred, very blurred as if it was shining from behind a fog. I can also say that i even saw something like it when I looked up after all of this was over but it was smaller and moved in a zigzaged formation an then it suddenly dissapeared.
