Stationary UFO over Guerneville, California

On May 29, 2015, at 18:00, a mother and her son spotted a stationary UFO at unknown elevation over Guerneville, California.

Witness report:

My mother and i were standing in our front yard. my mother's friend called and told us to look straight up into the air. we noticed an object that looked like a satellite but was stationary. it stayed directly in that position for hours without moving. it seemed to have matched the rotation of the earth and stayed there at an unknown altitude. my mom and i both thought "cool, our first ufo sighting." eventually, as the sun went down we lost sight of it. it seemed to have reflected the sun and not emitted any light.
