UFO Sighting in Fairfield, California on 2020-07-21 18:50:00 – Black orb between earth and sun

I was looking at webcams at (http://hpwren.Ucsd.Edu/cameras/) for fire in northern california when i saw a black orb in front of the sun. the orb was visible from multiple locations. i am attaching photos i downloaded. i thought it may be the moon, but i went online and the website made me think it wasn't in the right location to be the moon. the photos have the date/time stamp and location taken on them. it definitely made me curious. please let me know if you figure it out.
