Continuing to try and monitor the developments around the GRS.
Unfortunately seeing conditions were poor and fuzzy,and I note there was Jetstream present.
Blue data was particularly poor which may affect the colour somewhat.
- I believe the first SEBs circular/oval feature is at about the 9-10 o'clock position in the GRS hollow.
It does appear to be drawing off some red material from the GRS as John Rogers had projected.
- The second SEBs circular/oval feature,which has been distorted,is at the 12-1 o'clock position
- I deliberately tried not to oversaturate the GRS in the CH4 images,and I suspect that there are two lobes showing,which appear to correspond to the areas of the two SEBs features
- There appears to be a number of reddish spots scattered across the GRS wake,including a string of small spots running along the following edge of the GRS.
- The “chimney” directly above the GRS also appears to be drawing off reddish material
- As Andy Casely has noted,the disturbance in the SEBs/STrZ immediately following the GRS is very reminiscent of last years STrD.

Unfortunately with the worsening of seeing quality fell.
Even so many visible details being featured at the Oval BA and a small white oval just above it!
[ Observatory Parsec,City Canoas,Brazil]
Perfect conditions today!
A lot of details are resolved all over the planet. Oval BA is pale. The GRS is rising on the left.
Note the extension on the north side of the GRS. This extension is bright in methane band.
The SEBn is turbulent. The NEB is dark. Note the reddish feature on the NEBn close to the CM.

Poor to fair seeing. Oval BA is nicely seen.
