Hi Silken,
You're not the only one

. I ran into it by accident. Took me a while to find some info how to grow it...

.
It's a natural hybrid between C. guttata × C. harrisoniana from SE Brazil. I grow it in a clay pot with bark in my windowsill (NE side). Intermediate cattleya temps. When in growth twice a week water (one time with fertilizer). In rest once a week water with fertilizer. Needs to dry out between waterings.
I give a good amount of light (with morning sun in summer).
And of course lots of love

.
Greetings, Bindi
