Although the next Perijove will be on the other side from this impact point, i wonder if a disturbance could not drift along the Zone over the next Earth month (and many Jovian days) and be seen at that Perijove.
We'll see what we see in October.

The drift rate is pretty well-characterized by the amateur community, so one could figure this out without a lot of difficulty. http://jupos.privat.t-online.de/

I don't think typical drift rates are high enough to go nearly 180 degrees in a month or so, but that's just an impression.

I think that's still more or less true, but I neglected to think about the large rate difference between System I, the rate at which near-equatorial features move in bulk, and System III, which is what we use for navigation. After a month, I think those systems diverge from each other by nearly 140 degrees. See the equations at https://projectpluto.com/grs_form.htm

Regardless, we'll be imaging in October and we'll see what we see.
