Another Jupiter thread put the determination of a life time in and inspired me. I wasn't gonna sketch at all, just try hard as heck to see if LRS-1 could be seen. It was pretty much on the meridian. After about 10 minutes, there it was. Sure enough anyway. Well, I decided to sketch the moment, and I am so happy I did.
Gosh, where to start? The southern region was rather bland, let's start there and work north. The preceding limb the SSTeB was a bit lighter. I suspect that might have been those 3 ovals, haven't checked yet. (Edit: Just checked, yes those three ovals were in that vicinity.) The SSTeB was relatively dark and undefined with one white oval just seen. The SSTeZ was thin but distinct.
The STrZ was pretty featureless with a very faint trace of the STrB and some very faint, undefined darker cloud preceding the GRS. The southern half is distinctly brighter.
Okay, the SEB is always kind of difficult to pull features from. There was a whitish cloud near the preceding limb. However, along the southern SEB border, there were some faint undulations and the belt seemed to fade into another lighter cloud streak leading into the preceding limb. Those undulations were pretty cool. Interestingly, there does seem to be a soft blueish grey border forming just preceding the GRS. The white cloud feature looping over the GRS was interesting as it seemed more extended south. Now, the GRS itself was interesting. For a long time been trying to lock down the pattern of changing dark and lighter features. It does appear the southern edge is a bit darker as is the center. So, if called to lock it down, that's it.
Well, what can one say about the entire EZ. Again, there seems to be a predominate faint blue hue extending from the trailing limb. It's less obvious nearer the preceding limb. I'd really appreciate others confirming that. The zone itself was awash with alternating blue streaks and white features. It almost seems as if some of that festoon wash is forming along the EB. Quite beautiful and complex when the seeing settles and Jupiter burns into your retina.
The NEB seemed to have less pronounced undulation at this longitude. But it is distinctly darker along the EZ border and lighter across the northern edge. On the preceding limb was a particularly bright streak of cloud and one rift coming in under that festoon near center. Near the central meridian was a distinct cut in the northern limb with a faint extension protruding into that indention. You know what? I thought it might be one of those finger like extensions. It turns out to be WSZ! I didn't even realize it. So, that's what it looks like, eh? Yea, happy to have undertaken this sketch. Man, who would have expected to spot WSZ? Purely by accident, I assure you.
Now, the north. The reason I know the above object was WSZ is because I was so focused on LRS-1. Checking the meridian fro LRS-1, I noticed WSZ was just south. But, the whole purpose of this sketch was to observe and record LRS-1, darn it. It was going to be very difficult, and it proved to be. But, if you look closely, there it is trailing that darker cloud feature in the NNTeB! I'll be darned, it was a great find. Wow.
Lastly, and really fascinating to me, are those undulations in the NTeB just south of LRS-1. I had no idea, but they turn out to be a quite beautiful cloud feature. Truly, I was amazed and just so happy to have undertaken a sketch to document LRS-1. There was so much more to be seen because of the hunt for that elusive northern oval.
What a great night, thanks for sharing.

Edit: After further review, two features seem misplaced in the sketch. Can you spot them? No, not WSZ or LRS-1. Maybe they rotated some, but I doubt it. Just hard sometimes to place a fleeting feature, but the other more prominent one is just off. Hmmm...
