I could not make out what was on top but there was 4 spinning disks underneath and each disk was a different color.

I was outside with my dog and herd a loud noise in the sky. When I looked up I saw 4 large disk spinning. Each disk was a different color. Blue, red, white. I never could make out what was above the disk.
It flew over my house. I called for my 2 boys to come outside and see it. I thought it left but it flew back over my house again. As it was getting farther away we saw that things were shooting out of it. It looked like stars with blinking lights on each one.
Then there was a big flash of light and that 4 disc thing was gone but all the blinking things that looked like stars were left behind.
Then the whole sky filled with these blinking things . They were in groups of 3 in a boomerang formation. I counted over 13 sets of 3. I went in the house because my children were scared. After I calmed them down and went back outside all the blinking things were gone
