Image set from yesterday evening trying to cover the movement of the latest SEBs ring through the GRS hollow.
If I have my information correct,Hubble Space Telescope was scheduled to be imaging at this time.
What is quite remarkable is the size of the SEBs ring,which is not insignificant compared with the GRS itself and is competing with some of the SSTB ovals.
It also appears to have taken a more circular shape.
I have tried to highlight some detail/structure of the ring in the R image.
The critical period will be over the following 24hrs as the ring attempts to traverse across the mouth of the rift/chimney without being disrupted.
Regarding the CH4 images,and the 1827UT in particular(best data),
I am wary of raising expectations,but the upper right(NE) edge of the GRS appears to be a bit flattened adjacent to the SEBs ring,and there may be a dark rift developing across the NW corner.
Both of these features have been observed with previous flaking events. Further observations over the coming days will be important.

Here is a Jupiter image processed from the raw HST data obtained by Amy Simon and colleagues on June 26th.
The quality is of course exceptional. However achieving an accurate colour balance is challenging
(due to the violet filter used for the B channel) and took some time. Oval BA is nicely visible.
I processed another set from this raw data. This time the GRS is on view with Ganymede and Io alongside the planet.
Moons were processed separately but their positions are exactly correct for the time.
Ganymede was taken from the 0950 data set as it was just slightly out of frame for the 0817 set.
