SpaceX’s satellite tracker says Starlink will be visible throughout Arizona Thursday night around 8 p.m. and again on Monday.

PHOENIX — Residents across the Valley reported a string of mysterious lights streaking across the Arizona sky Wednesday night, but don’t worry, they’re not aliens.

SpaceX says it’s the company’s Starlink satellite network. The satellites can periodically be seen clearly when they’re in perfect alignment with the sun to reflect light back towards the earth’s surface.

The company’s satellite tracker says Starlink will be visible throughout Arizona Thursday night around 8 p.m. and again on Monday.

Starlink is meant to provide satellite internet service across the globe.

It’s not the first time the lights sparked curiosity across Arizona. The same SpaceX satellites were spotted from the west Valley to Tucson last November.
