I looked out my bedroom window at 4 am. a light appeared so bright.lasted 2/half hours. silent n huge diamond shaped disc. only moved upwards but on a slant. it was rotating and spinning very fast. I've seen it 3 times in this month of september. every time its the same time 4am. and around the same area. and does the same thing when the sun comes up it starts to descend .like it doesnt want to be noticed in the daylight.
