November 2020 Martian Dust Storm: Hellas Encounter

On 11 November 2020, a regional dust storm broke out in Chryse Planitia and quickly raged through Valles Marineris into the southern highlands. Starting on Day 6 of the storm (17 Nov), a long dust train gained momentum east across Sinus Sabaeus. On Day 9 (20 Nov) another dust train barrelled east across Noachis Terra, and on Day 10 (21 Nov) the two collided over Hellas Basin. Over a couple of days they coalesced into a crescent-shaped cloud that grew tentacular arms as it slowly dispersed eastward over the next week. This is that story, told through a modest Mak 180 and a meager DSLR on an ever-shrinking Mars…
