Discovered I had this feature in my archives and how it has changed over the years. It really did seem to be a mini GRS, almost as red as the GRS itself, but recently it has barely any red at all and has faded quite a lot.

Oval BA is a red storm in Jupiter’s southern hemisphere similar in form to, though smaller than, the Great Red Spot (it is often affectionately referred to as “Red Spot Jr.”, “Red Jr.” or “The Little Red Spot”). A feature in the South Temperate Belt, Oval BA was first seen in 2000 after the collision of three small white storms, and has intensified since then.

The formation of the three white oval storms that later merged into Oval BA can be traced to 1939, when the South Temperate Zone was torn by dark features that effectively split the zone into three long sections. Jovian observer Elmer J. Reese labeled the dark sections AB, CD, and EF. The rifts expanded, shrinking the remaining segments of the STZ into the white ovals FA, BC, and DE. Ovals BC and DE merged in 1998, forming Oval BE. Then, in March 2000, BE and FA joined, forming Oval BA.
