Amazing Video Shows Giant Spherical UFO Being Circled by Helicopter Over California

• When: August 28th, 2017
• Where: Los Angeles, California (San Gabriel Valley)
• What: Bright shiny sphere hovering, with helicopter circling it at one point

A really incredible daytime video showing a large, bright, shiny round object hovering extremely still has been uploaded to YouTube, and features great witness commentary. At the 3:22 mark in the video, a helicopter can be seen coming into the frame and curiously circling the UFO!

So far, this footage appears authentic, but I would love to find out if any others also saw this UFO over California. If you can share more about this sighting, please do! Is there a reasonable explanation, perhaps some weather balloon of sorts?
