1978 sphere inside cloud over Ukiah Valley, Ca beams of light radiated out from it after a few minutes

I was driving home thought the Ukiah Valley and the top of my windshield was lite up.  I looked up and a cloud had a light inside of it.  I pulled over and a hitch hiker was also looking at it about 1/2 mile down the road. At first it was a cloud but little by little I began to see a sphere.  Then beams of light came out like the star of Bethlehem.  I didn't know what was happening.  I had my camera on my car seat and thought to take a photo but for some reason didn't.  Then it slowly drifted to the west and went behind some hills but the sky was glowing about the hills.  I drove home and by the time I got there I had forgotten all about it!  The next day the Ukiah Daily Journal had a front page report of dozens of people reporting it.  Then I remembered but couldn't get the details.  It took days for it all to come back. I have also seen the same UFO in photos over Montreal and Mexico City.
