nice one... and cool it is blooming from such a small pseudobulb! Normally Cycnodes will bloom from larger PBs and will produce more flowers per spike... which only means you have a good plant
in this thread you will find some links with very good info on how to grow Catasetinae:
http://www.orchidboard.com/community...ff-hc-sky.html (Note: the plant in the thread is the same cross as yours, but the genus is wrong... Cycnodes is correct, as it is the hybrid of Cycnoches and Mormodes!) - FYI all Catasetum, Cycnoches, Clowesias and (in some extent) Mormodes, and all their hybrids (Clowesetum, Cycnodes, Mormodia, Fredclarkeara, Catanoches, Clowenoches, Monnierara) are cultivated the same way and are very easy plants if you understand and "respect" their needs... check the links and you will have great info ther!
as for your plant, I had never heard from the clon 'Jumbo Emperor' where did you get it from?
do not be irritated when surfing the web and you find several Cycnodes with different names which look exactly like yours
many of the yellow Cycnodes are very VERY similar and often difficult to separate from each other...
