Slow moving light looked like a star or satellite from south to north then abruptly turned east then stopped.

My husband and I are both 75 years old, retired professionals and have lived in this house for 37 years
We live in eastern Sierra foothills of California on 4.5 acres at 1400’ altitude on the top of a hill. I have a view of both east and west from my house. The back of my house has many large decks that have a spectacular unobstructed western view of the valley and west coast hills toward San Fransisco. It is from one of the decks that I viewed this event in the sky looking west. There are no street lights in my neighborhood. We do have some local ground lights from stores about 2 miles away. This particular early morning had no clouds so the stars were very visible. The moon was not in sight. I also live the flight path of Sacramento airport and have flown over my house many times. The time it takes from passing my home to touchdown at Sacramento is 7 minutes. I can easily see the plane lights on their dissent. They are very low. This object that I observed was so high that I thought it was a star. It was obviously not an approaching airplane.
AT 4:50am on 10/05/23 my dog started barking aggressively (something she has never done). I got up, went to her cage and let her out. She ran very fast still barking down the stairs to our very large fig tree in the back yard. I was trying to call her in and looked west to the night sky and noticed what appeared to be a star moving very slowly in a horizontal direction from south to north. At first, I thought it was an airplane but because it was moving so slowly, I then thought it must be a satellite until it changed direction and started moving east. My husband by then was on the computer checking our security cameras to see what the dog was barking at. I told him to come and see this light in the sky that was now moving northeast very slowly. Then the object stopped. No movement for a few minutes then it started moving slow again. At 5:03am I got my phone and started taking videos of this light. I then zoomed in (12% as far as my zoom would allow) and to my amazement I saw that it was now an orb and it was strobing multi-colored lights while spinning. The orb itself was white and the colors around the outside edges were green, blue, red, yellow and orange. It started moving again eastward then it stopped again. I took many videos with some being over 2 minutes. During one of the videos the orb expanded to 3 to 4 times its’ size for about 2 seconds then returned to normal size. It did this 3 times recorded on my video. My husband watched as I was video tapping but never did so with his phone. My cat was acting very unusual also by running around crazy on the deck while the dog barked on and off at the fig tree. Very unusual for this behavior. I watched this event until 6:15am when the sky started to lighten up from the sunrise. Also to note, our security cameras did not pick up any movement even though we have one on the deck that points to the dog door that my dog ran out of.
