Chain of lights 6:00pm, 12/15/25 above Bay Area

Time: 6:00pm 12/15/2025
Location: Above the Bay Area – California
I saw this chain of lights above earlier this evening. It looked like anywhere from 30 to 100 satellites that were perfectly in sync with their speed moving across the sky, and when I cross the street, the angle had changed slightly and none of them were visible. Satellites? Aliens?
