Reddish circular object proceeded west to east by northeast.I was just coming back from PDX when I just got to Beaverton. In the far west, I noticed a bright red circular shape that I figured it was simply a meteor. However, during the course of five minutes, it constantly stayed at the same speed without speeding up or slowing.When I got to the corner of SW 170th and Rigert, the object slowed down while starting to pulsate color red. The object went from the west side of the sky to the east. After the so called "sudden course change," the object proceeded to head north by north east but at a much slower pace.The course change happened by the time I managed to get up the north side of Cooper Mountain (SW 175th). By that time it continue to slow and head northeast towards Portland.
