The closest approach in mid-January next year will be a small approach with a maximal apparent diameter of 14.6 arc seconds. The period when the apparent diameter is 10 arc seconds or more is only for 4 months from mid-November to early March next year. However, during this period, you will observe the northern hemisphere of Mars just after the vernal equinox (λ=000°Ls).

A bright dust spreading from Chryse to Eos was detected by Clyde Foster's observation on the 18th (λ=314°Ls).
This dust event occurred at the same time period (Ls) as the one observed in 2020, and its location and initial shape are very similar.
I think from now on the brightness will spread southward from Eos and spread along Valles Marineris toward Solis Lacus.
The observable time shifts from the European side to the American continent side. Your continued observations would be appreciated.
