Here's what that string of lights in the sky over Fort Collins and Colorado was.

UPDATE, 8:15 p.m. Sunday, Feb. 12: Did you see that string of lights over Fort Collins on Sunday night? The Space X Starlink satellites were apparently seen over the sky yet again.

This Starlink tracker website says there will be two more good opportunities to see the satellites this week in Fort Collins: around 6:04 p.m. Wednesday and 6:14 p.m. Thursday. We'll see if the weather cooperates.

A SpaceX Falcon 9 rocket passes in front of the waning moon after liftoff from Cape Canaveral Space Force Station, FL Sunday, February 12, 2023. The rocket is carrying 55 Starlink internet satellites. SpaceX has now flown 69 missions carrying the satellites into orbit.

ORIGINAL STORY: Some people describe it as a string of lights in the sky or a slow-moving sky train.

On Sunday night, you might have seen such a formation in the skies over Fort Collins.

Are these intergalactic visitors or something more ... down to Earth?

If you were anxious about their origin, just know that the sighting followed the launch of Space X's 53rd Starlink mission on Sunday morning, when 53 internet satellites left Kennedy Space Center in Florida.

The satellites provide Starlink internet service, and after launch they appear as a bright string of lights in the sky.

A Starlink tracking website shows they would have been visible over Fort Collins starting about 9:44 p.m. Sunday. That site says they may be visible again on July 28, about 9:41 p.m.

Sunday's launch marks SpaceX's 33rd overall mission of the year.

The 52nd mission launched Friday night from Vandenberg Space Force Base in California, when 46 Starlink satellites were sent into orbit. Those satellites were also seen over Colorado.
