Normally we don't like to post flashing lights in the sky but this is clearly not a satellite or any known object. It is definitely not terrestrial so it is an enigma and it was taken by a UFO Hunter that we know to be sincere and honest.

The flashes were observed over two nights in the Oregon skies. They remain in a general location and sometimes flash brighter or dimmer between 8-10 seconds apart. The object flashes/pulses for over an half-hour and shortly after is no longer visible. This is a strange one indeed and one of my friends just reported seeing the same event. He lives about 7 miles away.
