Subject: EZ(S) disturbance (cont.)

Recent images of the EZ(S)/SEBn main complex are interesting, especially
with Tomio Akutsu's methane-band and I-band images.  The same images show
oval BA.
The images are on: 
	Aug.1 (Akutsu; Damian Peach's drawing on Aug.2 is a nice visual
illustration one rotation later).
	Aug.6 (Akutsu).
	Aug.8-10 (Akutsu, Miyazaki, and Don Parker ).
 There has been a large dark blue streak in EZ(S) around L1 ~ 190, very
dark in I-band, perhaps breaking up now, along with much other
disturbance, as last apparition. However the main complex itself is barely
perceptible in visible light, although it is still dramatically shown in
methane images at L1 ~ 235 as a huge 'step-up' of SEBn.  I wonder if it
will burst out again in visible light or if the disturbance is declining.
