UFO Sighting in Lake Forest, California on 2017-10-28 17:45:00 – 2 white spheres hovering (top left, bottom right) left of visible moon

I went for a walk with my mother, looked up at the moon, and saw two white circles/spheres on the left of the moon. they did not move or make any noise. continued to observe them over the next 20 minutes and they did not change shape or position. they appeared to be very high up in the sky. there was no cloud cover or fog. checked the skies again about 10 minutes later and could not see them.
