As of this morning, August 18, images by C.Foster show very bright dust activity along eastern and central Valles Marineris, bordering southern Chryse-Xanthe. We are at Ls 314, which is right at the upper limit for an encircling storm to begin, but a large regional event cannot be ruled out. We have had relatively little telescopic dust activity so far this Martian southern summer, and I encourage those that can view the area of interest to do so. Over the last few decades this initiation site has become more important than Hellas in generating dust storms, as I have discussed in the appendix to the 2020 Mars report (downloadable from the Section website).
Good luck!
