small circular disks above freeway in Clackamas OregonI live in Clackamas County Oregon USA, up on a Hilltop with a very good View of the eastern sky.I am located Aprox. 1 mile West of the 205 Freeway.On Monday March 2nd 2009 at Aprox. 4:15 p.m. I walked out on my deck to look at the weather conditions.I looked to the South toward the Oregon City area.I then spotted 4 small silver objects in the sky, they were moving fast from the South to the North, above the 205 freeway.Estimated altitude was 2500 to 3000 ft. They were flying together, but not in straight and level flight. They were moving up and down and weaving in and around each other.The objects were flying at the bottom of some low clouds, sometimes visible and sometimes hidden in the clouds.After viewing them for 15 seconds I grabbed my Nikon 12 x 50 binoculars from just inside the patio door.I was able to view them again for another 30 seconds before they were out of view. I was able now to see more detail.They were round circular flat objects, which appeared to taper down from the center to a fine sharp edge. I was not able to see any lights or windows, because of my distance from the objects. The diameter of the objects is difficult to determine but I think they probably were less than 50 ft in size.The objects continued to fly North above the 205 freeway area and disappeared from view.Total viewing time Aprox. 45 seconds.
