Saw a glowing orb move from north to south extremely fast (blink of an eye) and gone. greenish white light walking dog outside my house, looked up from cell phone and saw orb vanish behind a roof. thought it was a light from a softball field but when i went back to a vantage point to try to see the light i couldn't. i thought it was a street light but the street lights were crisp led white and this definitely had a green hue. flew southward, fast, almost like it was falling. no sound no impact definitely not a plane out of view, behind a roof and gone
