LOS ANGELES (CBSLA) — It wasn’t the aliens – that string of lights that were visible over Southern California were a string of SpaceX’s Starlink satellites.

The unsettling sight was spotted at about 10 p.m. Wednesday night and were visible to eagle-eyed sky watchers throughout Southern California. The lights were the 60 Starlink satellites that were launched into space on Tuesday.

The satellites were also visible over west Simi Valley and Moorpark, where Dennis Willett of the Ventura County Astronomical Society said he felt mixed emotions at the sight of an “internet satellite constellation.”

“Happy that so many less fortunate folks around the globe may soon have access to fast internet. Frightened that these bright light polluters could obscure the discovery of earth impacting asteroids,” he wrote in a Facebook post.
