Mt. Shastsa, CA pulsating, rotating lights at approx 40-50degree angle, east-southeast of Mt. Shasta, lasting at least 2-4 hours

In the eastern sky, more easr than south east of Mt. Shasta, moving back and forth VERY slowly, unsure of that distance of movement, with beautiful lights outlining the entire structure which was many, many feet high-the lights stayed on, but pulsating in a pattern of red-pink-white-yellow-blue-green around the bottom of the craft and along the structural outline.  It reminded me of the deep sea jellyfish that glow-the outline and tentacles shine with their own light. I also observed it splitting into two separate objects, like watching a cell divide.  The skies were totally clear,with a bright moon-one night short of a full moon. The craft had an oval shaped bottom, with a round, tall, beehive shaped body to the structure. The object was in the sky for a very long time, in fact was still there when I went to bed an hour later.
We spoke with this witness, and she sounded quite sincere to us.  However, we believe that she may have been looking at the star, "Sirius."  PD
