I had a really good session this morning with some good seeing conditions as the GRS was transiting.
Very likely that I will try and optimise my processing,
but in the interests of circulating without too much of a delay,kindly find the attached
A few comments:
- CH4: There are some fine methane bright features visible around the GRS,although no major flaking is evident at this point.
There also appears to be a linear Methane dark feature to the upper left of the GRS.
- IR: The second image is a bit sharper. Structure is seen in and around the GRS,
with one of the recent large SEBs rings visible in the GRS Hollow and a second about to enter.
There appears to be a small chimney formation at the top of the Hollow.
There is a lot of turbulent activity in the GRS wake,
also with some interesting structure in the SEBs following the GRS. An extension is also seen just preceding the GRS.
- Green channel: I was totally taken aback by this G channel image,not least of all the rather amazing structure of the GRS.
I am not sure how this relates to any of the SEBs movements,
but I had no other words than "Wow,that's stunningly beautiful" going through my head
(nothing to do with my processing,but what Jupiter is showing us!).
- RGB: I think this was the best I could get from the data so far,as the GRS approached the CM.
There is so much happening that it probably warrants a separate discussion.
All I will say is that I believe something is happening around the GRS but I'm just not sure what....!
It definitely deserves monitoring in coming days.
I was both pleasantly surprised and delighted to be contacted by legendary planetary imager David Tyler of the UK yesterday.
He had seen my Jupiter images of the 27 February, captured under good seeing conditions.
He is busy assessing new software (Topaz denoise) and decided to use my RGB image, specifically the GRS region to undertake some testing.
Although both myself and Dave agree that the result is on the limit of noise enhancement and artefact generation,
I do believe there are some potentially real details that he has managed to enhance that are both interesting and fascinating.
I acknowledge Dave's input and work on the image with appreciation.
Given Anthony Wesley's most recent image, showing an apparent flake developing on the nf edge of the GRS,
this enhanced image may have captured the very initial phase of flake generation on the n/np edge of the GRS,
possibly related to the "bulge" in this area.

Hi all,here's an image of Jupiter from this morning in poor seeing,
however after more than a week of cloud and rain it was nice to see the
planet again :-) The NEB looks quite active,and some interesting
details and colouration can be seen in the north polar region.
