Blueish orb moving west along skykomish river, unknown size or altitude. appeared to be much higher than commercial flight. made no sounds, color sort of undulated slightly but mostly maintained a consistent blueish color emanation. orb turned sharply and appeared to gain altitude and moved south. speed was constant. no sound, no blinking lights, no shape apparent other than a sphere/ orb. not exactly sure of time but believe it was around 10pm or so. sky completely clear.
