Spinning-top type UFO with multi-colored rings hovers 1 hour, sends out green "drones" then moves rapidly West until out of sight

While facing West at 11th + Elden, Los Angeles we noticed a UFO shaped like a spinning top with multi-colored light rings moving around it, similar to how an atom would look with electrons whizzing around it. It was producing flashes of color as we watched it. It stayed relatively low in the sky, well below airplane flight paths. We got out binoculars + continued to watch it as it stayed stationary in the sky. It was clearly spinning + flashing with a strange aura or energy field around it. While we were watching it, a police helicopter flew by it and stopped briefly, appearing to be checking this object out then eventually continued on. While we were watching this, 2 tiny green-lit crafts similar to small drones zoomed up over top of us then stopped directly overhead as we looked up at them. They stayed above us approximately 8-10 seconds then continued East-bound then they looped back in the direction of the UFO + appeared to return to the craft. Shortly after this the UFO began to rapidly fly West towards West LA + the ocean. We jumped in the car + tried to follow it but it was moving to quickly to catch.
