Jupiter streak.

Don't know if anyone else picked this out. In moments of absolute clarity from southern belt into the equatorial area, around midway at 9.55. Just before the pearl like Europa started across the disc.

Also some dark areas,

Great work and detailed sketch report, Nick. Not sure if we're seeing the same thing, but the other night, I picked up a darkish plume not unlike that shown in your sketch. The only difference being that is was pointing the other way round, going from the northern belt into the equatorial zone. There's a sketch in the first post to give some idea. I'm not sure if it because the relative distance and clarity of Jupiter has augmented in the last few weeks or because for some reason there are more storms going on, but certainly a lot more activity on Jupiter can be discerned.

Certainly seems to have changed visually over the last few months. The southern belt looks more tortuous with lots of detail . Certainly showed up brilliant colour and definition without a filter.

We've had our atmosphere washed and spun over here, which helps !

Do you mean the streak in the Equatorial band Nick? I've seen it a couple times but it is faint, I marked it on this sketch which has different longitudes than your observation but its still there. I guess it just needs those steady skies.

Spot on gorgeous, Mike.

HI gents,

I know this is about observing  etc, but over on the imaging- planetary section someone has captured your dark streaks here. They seem to match all of your observations...you boys are good ;-)

Regards

What a lovely sketch Mike,

The thin fine (plume) streak last night was from the defined edge of the belt right up into the equator, just one end of it was in the belt.

I had a real surprise to see it so clearly.

There have not been many occasions that I've not used a coloured filter and perhaps that's why I've not spotted this feature. Certainly these belts provide some stunning features under

Clear skies,

Nick.

Great observations and sketches folks 

I've not had a clear night for ages here, it seems 

This evening looks a bit more promising so I have my fingers and toes crossed !

Lovely sketches, something I will definitely will want to get into. I now have chair, just need to think about some sort of setup for that, and ideally a little bit more civilised temperatures so I can sketch without getting cold fingers

Likewise !

Just got absolute clarity for a moment looking at the GRS!

[cotterless45]

Yep had a lovely view of the start of the GRS transit . Clear area around with a lovely elongate clear area in the preceding belt . Then cloud arrived,

Nick.

[Steve777]

Yes, I noticed how distinct is looks; in fact one of the nicest views of the planet I've had Nick.

I observed a dark streak recently bordering between the NEB and Equatorial Zone and was thinking this was a Barge. However someone corrected to say I was seeing a Festoon. What I thought I could observe was very close to what is described here and I'm confused what to say I've seen! Definitely dark and visible. Of late, this planet has been supplying a few surprises, that's for sure.
