My first sighting was a few weeks ago, at approximately 3 or 4 am. the second sighting was on 9/24/2019 at 9:20 p.M. both times i was sitting outside facing south. both times i noticed the light moving at a high rate of speed. there was no sound. two houses to my south there is a tall tree. the tallest one near me. may be 200 feet tall. the light was 150 to 200 feet above the tree, the first sighting the light was moving more to the se, the second time the light was moving in a southern direction. the first time i saw the light my first thought was a falling star or space junk but there was no tail.And the sound, it was not a jet. i would like to know what it was. thank you.
