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. 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.

By now we have an idea of what that local chaos is like and we'll have the quandary of picking out the additional chaos. This will be the first time we've had a spacecraft this close to an event of this nature.

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.

did anyone do a 2021 mosaic of Jupiter from Juno images yet
there is still no Hubble 2021 map of Jupiter yet |

Yes. Sorry for the delayed reply: http://junocam.pictures/gerald/merged_maps/pj36/ SWEET that looks so nice i may use Hubble 2020 data to fill in the gaps |

As I recall, the upcoming Perijove is 16 Oct 21. Maybe we'll see something from the recent impact.
Has anything been spotted of impact effects from ground observations or HST? --Bill -------------------- |
