Silent near invisiable arrow, reflecting stars, moved across thes sky at night.The object was arrow shaped, the width shape of a boomerange and the size of a plane. It was black and reflecting the stars, like it was cloaked. It flew at the average altitude of a cropdusting plane when it dusts a field. It was silent. No noise at all. It moved across the sky heading north to south in the duration of 10 seconds.
