Hello,
Here are two images taken in Ca K on March 29.
A full disk image :

The same with different vizualization to show the chromospheric fringe. I am wondering whether the prominence on the west limb is the same as the big one visible on March 30 ?

Clear skies !

My goodness these are good

my favourite is the full disc with the chromospheric fringe, perfect processing!

I had a try with the C11 yesterday in CaK, absolutely no luck at all.
