I was sitting outside having coffee, suddenly looked up and noticed 2 tiny luminous white ovals flying from west to east at between 5-10 thousand ft. in the northern sky. They were "bobbing" up and down, so I thought they were birthday balloons or trash bags. After 2 minutes, a third appeared from nowhere. The sky was cloudless in that area. Then all three continued easterly, bobbing up and down but flying in formation. I have never observed anything "bobbing" yet moving at at least 100 mph. It was like they were dancing. From my viewpoint, they were tiny and high up yet driven and brilliantly white. Even though I wear corrective lenses with tint and polarization, I had to put my hands around my eyes to separate early sunlight/distortion. About 5-6 minutes later the Air Force appeared with 6 planes about 30-40 thousand ft up spraying "chemtrails" (they always start (here) from the north and fly south before changing directionally and fly west to east). Today the planes started from the north and minutes later they began a diagonal pattern from the north, not the usual checkerboard pattern. The 3 oval/orbs continued easterly until they left my vantage point and probably continued over the Cascade mountains. This is my 3rd sighting of (UFOs?) since 1962, and my second sighting this year. Strangely, I feel that I will have future observations.
