4-5 UFO's (orange lights) circled around a bobbling circular UFO mother ship (white light with a red light on the top or rear)Sighting event: At approximately 04:30AM PST I went outside to retrieve the morning newspaper. After exiting my house I noticed a brilliant full moon with some visible stars and scattered clouds in the sky. The newspaper had not been delivered yet and then I noticed a bright light that appeared to be bobbling and weaving around. The light had a red light at the rear or on the top of it. I returned to the house and recovered my 7 x 35 binoculars and went outside again to view the object more. It continued to bobble to and fro, up/down, and around. It stayed within approximately a quarter mile radius. While watching the object I observed a dim orange light approach the brighter white light which did not blink or flash. The orange lights came different directions to the white light, circled around it and then sped rapidly away in many directions. This occurred during my observation of all objects until I quit watching approximately 05:45 PST. My spouse a! lso observed the objects.Location of objects: The bright non-pulsing white light with the red light on the top or rear was located approximately 240 degrees in the Southwest direction from my property. It appeared to be 15-20 degrees above the Sierra Nevada mountains (Carson Range) above Lake Tahoe. I estimate the objects to be 10 to 15 miles distance from my property during the sighting.
