A spherical object spotted hovering silently over the San Gabriel Valley this week had residents gazing skyward and wondering what they were witnessing.

The object appeared in the sky over the San Gabriel Valley Monday morning.

One video, posted by YouTube user Julian Lopez, appears to show a Los Angeles County Sheriff’s Department helicopter circling around the object for an inspection around 7 a.m. over West Covina.

“Well, my friends, there’s a UFO over the San Gabriel Valley,” the videographer said.

“A helicopter is circling it,” he added. “It looks like a big eyeball.”

While the object resembled a large balloon, “There’s nothing holding it down, though. That’s the thing,” Lopez.

Lopez said he had just finished washing his car when he spotted the object out of the corner of his eye.

The sphere was metallic gray in color and made no noise, he said.

“It was just weird because it didn’t budge,” Lopez said. The witnesses went into his house to tell his 6-year-old son to come take a look, as well as to retrieve his cell phone to record video.

The man and his son watched as two helicopters flew in close proximity to the object. At least one of them circled around it before leaving the area.
