Multi colored bright flashing light in WSW Sky as seen from about: N 43 49.49 & W 121 28.14August 14, 2010 23:15 Went outside to cool off a bit prior to going to bed. Noticed a brightly flashing object in the WSW sky. Thought it was an airplane because it had several different colors being displayed. It was the brightest object in the sky except for Jupiter which was to the east area of the sky. Moon not visible as it had already set.As I watched I realized the flashing lights did not move in relation to the trees in the yard of the house next door to the south of me. After 5 minutes (40 miles of jet airliner flight distance) it still remained in the same position.I walked to where my driveway meets the street some 100 feet west of where I first spotted them to get a better view of the lights. They were still in the same place.I returned to my house side door and retrieved my 20X80 binoculars to determine if I could see anything with the use of them. Going back to the driveway entrance I used the binoculars and could see that the lights were changing colors and very quickly. Red, blue, white, green colors were visible with the glasses but of course the image was all over the place. I placed them on the top of the fence post at the entrance of my driveway and although it steadied the image somewhat it was still only a bouncing globe of lights moving around. Like trying to watch a star with high power glasses, almost impossible.Although I watched the lights for about 30 minutes, less the time to get the binoculars, they appeared to remain the same intensity and with multicolors.The position was about where I would expect to see Arcturus, the star the tail of the Big Dipper leads to. Maybe it was that star, although I have looked at it hundreds of times, including from the flight deck of jet airliners. I have never noticed it have coloring and flashing brightly like it did tonight.The object was about 35 degrees above the horizon and the sky is clear although there could have been some smoke from the forest fires that occur this time of year adding particulates to the atmosphere and perhaps giving a view that I have never seen before.I stopped watching at 23:45.
