Observed an extremely bright light north of us rt 30 while driving east on the road. was far too bright to be a star/planet. the light appeared stationary, was white in color, and did not flicker at all. there were no additional lights and no tail. because i was driving i could not maintain constant observation. after several seconds observing it at the constant luminosity, i glanced back from the road and it had dimmed, but continued not to flicker and stayed at the dimmer luminosity for several seconds. several seconds later i glanced back from the road and it had disappeared. do not now if it “left”, landed, or just vanished.
based on the sighting i can rule out a plane, helicopter, star/planet, or man-made satellite. because of the light appeared stationary, did not flicker at all, and had no tail a meteor seems very unlikely.
