8 Silver/Red Flashing Lights Seen Hovering Very High Above Los Angeles By Three Women

Two friends and I were hanging out by our pool when one of us noticed the ufo’s.  One of us is a high school teacher, and the other two are in film production.  We could all see at least 8 objects that were hovering very high up.  They looked like tiny dots of light that would flash red sometimes.  They moved very slowly, staying mostly together, but sometimes moving closer to one another and sometimes moving apart.  Coordinated enough to not be balloons, and not ever moving up, only across, southwest.  Also too high and not coordinated enough to be drones.  We could see them for about 10 minutes and for a few more minutes we could see only one of them.  Not sure if they vanished or went behind the building.  No sound was made by them.
