UFO Sighting in South San Francisco, California on June 22nd 2015 – we saw a round object with three large lights above us it moved south and appeared to sit on mountain

the kids were playing out and called me to come look at a strange object. since we live in the san francisco airport flight pattern I assumed it was a plane.I saw three white single lights in a triangle that I thought were planes in formation. I saW tWo planes leaving the airport and one coming in. Then I saw the circular object with three lights flying over the area. It disappeared for a while and then came back. the children said it looked like it landed on the mountain. They became scared and came in the house I am just wondering if anyone else saw it. I hato pictures on my cell but I do not know how to download it to site
