Strange Red Shot passing the ISS on Aug 11, 2015

On August 10, 2015, NASA caught a strange red beam on its ISS live feed camera and it looks like a projectile passing the ISS.

It could be a laser to create an artificial guide star for use in astronomical adaptive optics imaging, but such a laser light does not move in the sky as astronomical sources do.

Could it be a secret launch into space or is it just a glitch in the camera?

It is not the first time Streetcap1 captured such a red beam near the ISS, but so far, there is no explanation for this phenomenon.
