It seems this is not a rod (but probably a bullet) since comparing frame by frame, where the "rod" ends in one frame, it starts in the next frame. So I would say this is a bullet.
If it were a rod it would overlap between frames.
And the fact that the sun is very low, shining from the side, makes the bullet more visible when the ground is dark.
What does not compute for me is why the object is visible so far away.
It could be a tracer bullet, generating some smoke, and that the smoke could make it visible from far away in this lightning condition.
Is there maybe a shooting range in that direction?
