>changes trajectory
>still on on same course around the sun
if it changed and headed straight for earth that would be something.
>Trajectory Stability: Despite its unusual activity, 3I/ATLAS shows no evidence of non-gravitational acceleration or course deviation that would alter its path significantly, Its motion is governed solely by gravity and its initial velocity.
>Tail Reversal: The shift from an anti-tail to a classic tail is a change in mass-flow geometry, not trajectory, this is explained by the changing dominance of different ices as the comet nears the Sun
nothing burger so far

There were reports that there are multiple objects travelling together, so could be both.
although it would be helpful to know where these images came from
