On Tuesday, January 29th, 2019 at 8:26 pm. I was traveling southbound on freeway 99 by the Fresno river and over the Arbor Vitae cemetery I noticed a triangular image with 4 bright Led lights hovering over a dark area in a standstill. It appears just over the tops of the tree's in the cemetery. I got off the freeway to go take a closer look and it vanished. It was something I have never witnessed before and much larger than any drone and smaller than an aircraft. I went to grab my phone to take pictures but it vanished.
