Twenty new moons of Saturn, giving a total of 82 moons. Jupiter now in second place with 79.

Not bad, many thanks for the lot...I suppose that the orbital elements are either known with substantial uncertainties or partly not known at all?
The 62 known moons show a somewhat similar motion profile as the twenty new ones.

if the new moons are in horizons , then it will be time to update the spice ssc for saturn

Right. I am just a bit worried that with so many objects the performance will be significantly slowed down with spice...? What do you think?

time consuming for sure , but if i do not add "before & after" SPICE orbits it is a easy copy / paste and minor edit for each one .
