I see they caught a satellite, pretty common actually, can't count how many images I've taken that have streaks in them from satellites, can always tell the spy satellites since they are in perfect north south orbits (so they can cover the entire world as it rotates). I guess now there are a few private commercial imaging ones in the same type of orbit, but most are spy satellites from various countries.
Edit: Took a while to figure out where in the sky that is, thought it was a wider view but it looks like it's not even the entire constellation of Orion. On it's side (obviously since the stars are moving top to bottom), north to the left, Orion nebula on the right side. So that satellite is in an orbit similar to the ISS or Hubble.
