Clyde Foster
I was able to have  reasonable look at the track of the upcoming Juno PJ33 flyby this morning,two days before Perijove.
There should be a number of interesting features that Juno should be able to capture during flyby,
but I am particularly hopeful and excited that Junocam may be able to get a really good look at DS7,
the remnant of Clyde's Spot,which appears to have been showing some activity recently.
Some other potential targets:

a. NN-WS-6: Maybe a bit far west,but there is also a reddish oval to its NE (Juno may go close to this),
with some features near it.
b. There is a feature on the edge of the NPR(approaching the limb in my RGB)
c. The NTBn waves
d. Juno should be close to WSZ and the nearby reddish barges
(the one sp the WSZ has a white feature below it that may be interesting)
e. The festoon may have moved a bit by the time of flyby
f. The disturbed and clumpy SEBs,with a small red spot.
g. Therefs a few small STBs jet spots near DS7
h. Oval A1,also with some nearby dark spots.

J.Rogers>>Thanks for those excellent images and for your encouraging previews of PJ33 (this Thursday).
J.Rogers>>Actually the track crosses the equator at L3=311 (L1=109,L2=161),
J.Rogers>>as given in the current table on our BAA web pages,so you must have got an out-of-date list;
J.Rogers>>is it still lurking in our pages somewhere?
J.Rogers>>Anyway,the longitude is not far from your value and the features you list should almost all be in view,J.Rogers>>with the possible exception of NN-WS-6. Attached is a copy of the latest map with the approximate track marked.
J.Rogers>>This map has not been rolled forward so features will have moved,although not by very much except for the EZ.

J.Rogers>>It turns out that we should get a spectacular closeup of White Spot Z on the NEBn edge!
J.Rogers>>I had not previously realised this as WSZ was obscure in the later months of 2020 due to the NTBs outbreak;
J.Rogers>>but it has reappeared as prominent as ever.

J.Rogers>>And indeed we should get a great view of the S. Temperate domain from oval BA to DS7 and beyond.

J.Rogers>>Observers: Images of this region in the next five days would be very valuable.
J.Rogers>>And remember that PheMus are happening,too:
J.Rogers>>there is a total eclipse of Europa by Ganymede on April 15 at about 10:12 UT,which would be visible from the Caribbean region.





J.Rogers>>I checked again and realised that you had used an up-to-date table but got the longitude of perijove
J.Rogers>>(at 28.8 deg.N),rather than equator crossing.

I finally had clear skies and better seeing conditions.
Jupiter is still very low in the sky at less than 40deg.
This is the calm before the storm because we have an in coming tropical system.

The GRS is setting on this image.  There are some outbreaks on the wake of the GRS.
The GRS halo is very dark.  The SEB following the GRS looks very pale.
The EZ has a strong reddish hue over it's normally yellow color.
The NEB is quiet and pale in this region.  There are no outbreaks on the NEB!
Is the NEB fading?  Note the dark band over the NTB with its wavy feature.
