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. --Bill -------------------- |

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. -------------------- Disclaimer: This post is based on public information only.

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. -------------------- Disclaimer: This post is based on public information only.
