Condition was very challenging today. Seeing was very unstable and transparency was poor.
These images show the GRS,Oval BA and the NTZ Outbreak #1.
The days of this outbreak is numbered as it approaches the tail of Outbreak #2.

Surprisingly not bad conditions with a fairly breezy jetstream overhead last night,23rd September.
Here’s the first set of images,which has the still very energetic NTB outbreak #1 rising,and the tail of outbreak #2 setting.
Methane has come out well,with good detail around the GRS,Oval BA and around the NTB.
Influence from the spreading fan of the tail of #2 appears to spread quite well south into the NEB (IR & RGB),
and north of the NTB (RGB,IR & CH4) near L3 = 35deg.
There is a narrow pale streak in RGB along about half of the last remaining quiet area of the NTBs (this is L3:45-90deg).
The tail of #2 can be traced in IR to disturn the NTB up to L3: 53deg.
The GRS once again shows a spreading fan of material p. the GRS,but despite good resolution,none of this shows in the CH4 band.
One more set of images from the 23rd to follow
Here are the remaining images from yesterday,23rd September. Seeing was mixed but better than expected.
With Outbreak #1 transiting in this set,
I have processed these to minimise overexposing the outbreak,and there are fair details in IR & CH4.
Interestingly,it appears from overlaying the maps
Hey Clyde,nice spot on the darkness of that segment! I think Anthony saw the same on Monday,
while we were on IRTF and he was showing off live imaging from QLD - in the same region,
the same dark segment was prominent behind outbreak #2.
It seems to be another darker segment that sows up especially prominently close to the limb of the planet.
My image,blinked in the linked and attached animation of a map from yours and mine,7hrs apart,
shows the same segment,but rotated to the p. side of the planet.
The segment shows up really prominently on your image and Anthony’s,but not so much on mine.
Because mine has it nearer the meridian,you can also see it seems to be composed of some “undisturbed”
NTB ahead of plume #1,plus a dark segment at the very tail of #2.
So I’m not sure if it’s a precursor to the new NTB,as I think Outbreak #1 is about to make a mess of it,
but I have no idea if it resembles what we’ll see later on.

2020_09_22 and 23. Something create a pattern in the images,
I don´t know where is the problem... Some of the my last images show the pattern,to.
[Jose Antonio Soldevilla Canyelles-Barcelona-Spain]
Early evening set showing the 2nd outbreak approaching both light and dark features preceding it,
which I assume to be tail remnants of outbreak #3. Possible dissipation of the 2nd storm shortly?
A later set from yesterday evening showing the impressive large scale features in the tail of NTB outbreak #2.
Oval BA and the GRS are just coming into view at lower left,with DS6 preceding them and DS7/Clyde's Spot remnant near the CM.
There is quite a cluster of ovals in the vicinity of LRS-1 in the north,best seen in the IR.
A very noticeable dark line can be seen in the CH4 in the NTB.
I am wondering if this is a precursor of the anticipated new NTB?
