NEB rifted region emerged early August developed to a grand scale disturbed sector of the belt over 100 deg. long. The p. end of the region reached II:70 deg. late September, and it will soon return to the original longitude (about II:40 deg.) after encircling the planet. The region was still active with many white spots inside. Another rifted region emerged late August also developed as expected. In Einaga's map on Sep. 11, it formed oblique band from preceding-south to following north direction ranging from II:40 deg. to 60 deg. It seemed to have developed more by the end of September, when the p. end prograded beyond II:0 deg. This month, one more rifted region was formed at II:127.4 deg. (Sep. 11, Kumamori), again north of RS. The rift also developed longitudinally into wavy band at II:40-60 deg. by the end of the month. The long rifted region described above was approaching immediately following the new rift, and two regions were overlapping each other.
RS was still Hollow surrounded by dark arch on the south at II:128.6 deg. (Sep. 11, Einaga), and STZ large oval was passing it. Dark streak in STrZ emerging from RS extended to II:90 deg., north of BA, early September, but it decelerated since then as if it was trapped by BA, and relative position with BA hardly changed by mid-September. Since Sep. 20, however, it again extended rapidly, and Kumamori's image on Sep. 23 showed a continuous dark streak from RS to tens of degrees in longitude preceding BA. Originally there was fragmentary streak along SEBs edge in this sector, but new streak seemed to have replaced it. By the way, bluish patch in STB at around II:210 deg. following RS was a remnant of formerly observed STB segment.
In SEB, white cloud activity of mid-SEB outbreak continued in the range of II:290-20 deg. Another outbreak following RS seemed to have stopped, because distinct spots were not seen. Instead, dark component in mid-SEB was prominent in this longitude.
This apparition, NTB was widely separated into two components with considerably orange color. Disturbed bluish segments were growing on NTBn, and they were remarkable at II:150-190 deg. and II:320-340 deg., this month. Though NTBn markings generally retrograde with North Temperate Current-A (9h56m), these segments were almost stationary relative to System II.
