Four orange fireball looking objects floating in sky, no noise, flew away one at a time4 orange fireball looking lights just floating in the sky in a diamond formation. They were spaced apart pretty far so they're definitely not a single plane. Started off very bright then dimmed out. They left one at a time. Also, they made NO NOISE so they're definitely not helicopters. There are plenty of helicopters in my neighborhood and it only takes one to make a lot of noise. There were FOUR fireballs and there was no noise. Very excited about this.
