Viewers in Woodland Park, Fountain and Trinidad all shared video or photos of apparent flying lights traveling in a linear path across the sky Tuesday evening.
All three viewers said they saw the lights moving in unison between 6:30 p.m. and 7 p.m.
The lights probably aren't drones or helicopters or planets.
Instead, they're most likely a group of of SpaceX Starlink satellites, a team of low Earth orbit satellites that aim to provide affordable internet to the United States and Canada by mid-2020, according to CNN.
SpaceX launched an additional 60 satellites just a few days ago on Jan. 6, growing their "constellation" to more than 100 units. SpaceX intends to pursue more launches this year, bringing the satellite 'train' to over 1,500 satellites, says CNN.
