Blue and white circular ball falling to earth spotted in Northern California

My friend and I were in our neighborhood park when all of a sudden we saw a bright white and blue circular object drop from the sky super fast and maybe crash. I thought it might be a meteorite but it looked like a ball in the sky and went straight down, not diagonal from our view. It was very bright white and blue like the color of the sky in the morning inside the ball. It went down so fast from high in the sky down to earth in less than 3 seconds. I couldn’t even take a picture as I didn’t have enough time to grab my phone. The sun was mostly down so there was no way the sunlight could have distorted our view. It was not a drone. The sky was clear and darkening. There was no trail or smoke when it fell. A coast guard helicopter flew by less than a minute after and I am sure the pilot seen this as well.
