I described the seeing conditions for this Jupiter session as "pretty hopeless" in my notes,
as I had another dramatic degradation in seeing as dawn approached(a regular trend recently).
Despite multiple stacks,I was not able to resolve any detail of the outbreak in the CH4.
However,some structure is seen in the IR,and I was taken aback that some large scale structure was also detected in the RGB in the region of the outbreak
(I only captured one of each channel,thinking I was wasting my time...
I should have learned by now to have more faith in the software....).
I see that the STB dark spot is approaching sp the GRS quite closely now,
and also that the extension off the preceding edge of the GRS appears to be interaction with the features just s of the SEBs.

I was excited to have the seeing conditions be much better today than the last few days.
Interestingly to note is that my IR image from 04:28 UT is very close in time to the RGB image from 04:17 UT,
so the IR and RGB structures can be compared nicely between the two images.

I processed Ganymede separately combining the red,green and blue images from the 7 RGB runs I made,
then stacking and integrating them in Photoshop,before a small sharpen.
I felt the detail in the raw images warranted this. Although I derotated and integrated the 7 RGB runs for the planet to give a low noise result and hence a high SNR,
I also derotated and integrated the central RGB run.
This gave a fairly precise location for Ganymede so that I could insert the sharpened image at the right location.
The image of Europa is simply from that central RGB integration and there is virtually no smear.
It is located next to the very bright break out in the NEB on its p side.
I have magnified the moon and put the WinJUPOS graphic showing the anti-Jovian Hemisphere alongside.
The bright crater Osirisis is clearly to the south and the large darker albedo area of Galileo Regio to the north like a French cap.
In between there is quite good detail of Marius Regio.

An image of Jupiter from June 4th in reasonable seeing showing Ganymede & Europa transiting &
Io just off to the F limb side of Jove,having recently emerged from behind.
The GRS is also on display revealing quite a lot of turbulence in its' wake.
