Nevada desert near Area 51 captured footage of a strange phenomenon

This flare or orb seems to maintain a specific distance from the ground ascending and descending with the contour of the terrain.

I stabilized this as much as I could. The original will be in the comments.

As reported, "A random traveler in the Nevada desert near Area 51 captured footage of a strange phenomenon. Could this be a secret weapon, advanced technology, or something extraterrestrial?"

I've seen green tracer rounds before, but never a flare that you launch horizontally like that. Any ideas?
