Hot weather had heated up the ground and it was hard to even make out the two EBs most of the time through the turbulence around dusk and at such low altitude (~34deg) - but then a 10 minute pocket of more stable air drifted through from somewhere - the planet was putting on a good show. Very soft result, but I was stoked to get another image of the GRS region - probably the last for me from this apparition.
Thanks for looking. Ray

An excellent result for that alt Ray, very well done.

thanks Trevor. I was very pleased to get this. However, the worrying thing is that this will be about the highest it gets next apparition. Might have to invest in an atmospheric dispersion compensator.

Looks good Ray - lots of action in the bands!

Nice one Ray :)
It would be interesting to see what you could get at this elevation with good seeing.

Hi Matt - most interesting is that the dark band of the NEB seems to be getting narrower.

hi Rob. this will be about the best elevation we get next apparition so hopefully seeing will occasionally be better.

Like said ...It would be interesting to see in good conditions and a higher alt.
But it is great for where it is sitting.

Great capturing Ray, How interesting is that red flang below the GRS and trailing left, makes me wonder if its sucking up surface elements ? It should hang around for a while, maybe enlarge at a guess ?

Thanks Kev. at least we are getting some clear sky, even though the altitude is so low.

thanks Bob. my understanding is that the orange/brown region is a jet being dragged under the GRS and then into the swirling turbulent eddies on the RHS of the planet image. as far as I can tell, the jury is still out on what materials the darker stuff could be - it seems that the whitish stuff is most likely ammonia ice.
