There are two visible objects in the California night sky. They do appear as "perfect circles", and of course could be spherical. They are bright and obvious. CBS sent out a "street team" to look for them, and individuals furnished brief videos to CBS.
"It wasn't immediately clear what the source of the light/objects was".
"Only the shadow knows"!! :))
