Not sure but I think the dark spot is actually Titan and I have a sharpening artifact near the left edge (if my planetarium program is accurate time wise - it has had errors before).

You are quite correct, Sirrah! Thanks to you kindly including date and time I can it was nigh on dead centre 11:50 UT (near my local noon). At least that's what winjupos reckons, and also Guide 9.0. The shadow transits don't seem to be happening yet, but from the look of it if you can detect thet delta mag twixt Titan and Saturn, which aren't massively different in colour hue, then once the eclipses start you will be extra truly impressing us!
I haven't allowed for our difference in long and lat (all my stuff of course defaults to my long and lat) and just decided it was negligible in this case, after all there won't be much Tital-Saturn parallax due to proximity of both to themselves, sort of thing (warning : my jargon can be wrong as well as illusionary).
If you go here https://ssp.imcce.fr...tellites-events then take the drop down for systeme planetaire (should be self evident), then take Saturne, keep epoque as current date (when predicting ahead in time) and set your days ahead accordingly (nombre de dates), you will note the maximum is 365 dates, ie one of the years, then for the loo observation site bung in 500 which is the MPC code for 'geocentric'. If you got to the Minor Planet Center and dig around you'll find a list of their station codes somewhere so you can pick an observatory nearest you (even easier if you so happen to have one of said yourself!).
Then press the calculer button (I wonder what that means) and you'll get the Phenomenes listed underneath. Fortunately la francais ain't much different here from the Ingerlander tongue so it should be more or less. The table appears on the same page underneath so you'll have to scroll down a bit (at least that's what happened on my browser), click on the little cogwheel next to the button with the word exporter on it and you'll get a key that's plain enough. I'm guessing ombre means umbra means shadow, and I guess passage means the transit of the satellite upon Saturn's disc, after all they aren't the same except at near opposition = superior conjunction of Saturn. Looks like the mutual events are in there too, ie satellite on satellite action, plus fraction of moon eclipsed etc, however I dunno what units D® are in, whether Saturnian radii or whatever, the event duration and what appears to be the arcsecond offset from centre at time of event already have columns, so someone Francais proficient will have to check out the documentation, it has a diagram that may help. D® is apparently the distance of the satellite to the planets rim reported in planetary radii at the instant of maximum event.
Remember EXPORTER, you can save the table.
I think they run observing schemes too (there are reports there like PHEM15 and PHEM21, probably more to do with Galilean Satellite mutual phenomena) so I suppose could have a play with that, although timing is a tight thing in asronomy, especially if good astrometry is needed too, which might spoil all da fun.
For example for today, amongst others, we get this
2024-05-29T09:47:21.319 26.88 606 PA.D 0 -0.06 7.94
2024-05-29T13:25:45.659 27.12 606 PA.F 0 -0.07 7.89
Passage "debut", PA.D, at 09:47:21 UT, Passage probably "finale" at 13:25:46 UT, the object is 606 (sixth satellite, ie Titan, of sixth planet, ie Saturn, planet number given first), The duration from start to finish is 3h 48m ish if I can add up properly (not always assured), half of that is 1h 54m (check that), add that to start time and we get just over 11:40 ish for midpoint and midtime, not fair from your 11:50 and image showing Titan near Saturnian central meridian, give or take a yard, working in approximate figures.
Ya know, this stuff nearly works sometimes! Anybody would think astronomy was a science 
PS Nice image, as I say if you can discern the disc upon the disc, the disc shadow upon the disc should be easier. I think I read or worked out somewhere that the shadow was about an arcsec or so across, but that could be my memory playing games. Also, not sure if the eclipse shadow will be perfectly circular or not, possibly extended west-east, trying to remember back at some simulations I tried in winjupos a while ago and hoping I'm not getting muddled with something else I was looking into recently.
EDIT : I think I got shadow occultation and possibly eclipse transit back to front, or at least one of them! EC.D seems to be satellite in planet shadow. Looks like shadow transit ellipse can be circular and non-circular depending on where on limb and projection angle, ie over the duration of an event.
ADDENDUM : one decentish one for Europeans is about twenty to eight UT on night of 20/11/2024, albeit Saturn at only 30 degrees ish elevation for 50 degree ish latitude. There may be others that I've missed but I noticed that one. Moon rise at just after eight UT.
