''SSTB Ovals'' - White spots at 40,5°S, long-lived anticyclonic circulations, named as A1, A2, A3 ... Their drifts lead them to overcome the GRS about once a year.

''BA Oval'' - It is the result after the merging of three pre-existing ovals, during the year 2000. It is a large anticyclonic circulation, close to the latitude 33°S; in the year 2005 its color turned into a pale red. Its drift leads BA to overpass the GRS about every two years.

''BA Oval'' - It results from the merging of three pre-existing ovals in 2000. It is a large anticyclonic eddy, close to latitude 33°S; in 2005 its color turned to a pale red. Its drift rate causes BA to overtake the GRS about every two years.

''STB'' (South Tropical Belt)- Belt whose color intensity is variable as well as its latitude, variable in longitude.

''STB'' (South Tropical Belt)- Color intensity and latitude of this belt vary according to longitude.

''GRS (Great Red Spot)'' - The edge is sometimes marked by a dark ring; nowadays the inner area has a pale red color. Its size is gradually shrinking.

''GRS (Great Red Spot)'' - Its border is sometimes marked by a dark ring; the inner region is currently pale red. Its size is gradually shrinking.

''SEB'' (South Equatorial Belt)- This belt periodically disappers, then an outbreak reinstates its ususal activity.

''SEB'' (South Equatorial Belt)- This belt disappears periodically; each disappearance is followed by an outbreak that restores its usual activity.
-
''EB'' (Equatorial Belt)- Sometimes this thiny belt arises in the Equatorial Zone; it is a temporary feature: then the belt slowly disappears to born again during the more intensive periods of activity of the planet.

''EB'' (Equatorial Belt)- Sometimes a faint belt develops in the Equatorial Zone. After its formation the belt slowly fades away, only to reappear during the periods of most intense activity of the planet.
-
''NEB''  (North Equatorial Belt) - This belt is the darkest one of the planet, active both in the inner area and in the edges. Periodically it broadens Northward and then it shrinks, about every four years, with production of white ovals and dark spots along the broadening edge.  
+
''NEB''  (North Equatorial Belt) - This belt is the darkest on the planet, active both along the edges and in its inner regions. About every four years it expands northward, and then it shrinks back. This phenomenon entails the production of white ovals and dark spots along the broadening edge.
-
''WSZ (White Spot Z)'' - E' nata nel 1997, come una delle tante macchie bianche (anticicloniche) che appaiono a 19°N. E' caratterizzata, oltre che dalla longevità, dal moto veloce (verso longitudine decrescente), che la porta a interagire con altre macchie della sua latitudine, generalmente stazionarie nel Sistema 2. Nel mese di novembre 2013 ha assunto una debole colorazione rossastra.

''WSZ (White Spot Z)'' - This spot formed in 1997, as one of many (anticyclonic) white spots at latitude 19°N. A long-lived spot, characterized by a fast prograde drift that brings this spot to interact with other ones sharing the same latitude, but that are usually stationary in System II. In November 2013 its color turned to a light reddish hue.  
-
''NTB'' - Come la SEB e la NEB, è sede di periodiche eruzioni di macchie bianche e condensazioni scure, che producono velature nell'attigua zona (NTZ).  
+
''NTB'' (North Tropical Belt) - It undergoes periodical outbreaks of white spots and dark condensations that produce veils in the neighboring zone (NTZ), in the same manner as SEB and NEB.

''NNTB'' - Di aspetto variabile con la longitudine; presenta segmenti più marcati.  
+
''NNTB'' (North-North Tropical Belt) - Its appearance changes with longitude, with some more noticeable dark streaks.  
-
''Piccola Macchia Rossa (LRS) in NNTZ'' - Poco appariscente, ma estremamente longeva: risale almeno al 1993. Si trova a 40°N, e periodicamente si colora in modo più intenso.  
+
''LRS'' (Little Red Spot) in NNTZ - Hardly conspicuous, but long-lived feature. Placed at latitude 40°N, it formed as early as 1993. Periodically, its red color becomes more intense.
