Any idea?

Does anyone have any idea what this could be?
It's a looks like there is some nodosa in the background, a nice big yellow lips with somewhat thin yellow petals/sepal with slight red shading on the edges.
Your help is greatly appreciated.

It's lovely whatever it is

A better front-on picture of the flower would be helpful instead of this awkward low angle. A good picture of the whole plant would be helpful too.

Is it just a single flower, no other buds or maybe just one more on the spike? One leaf per pseudobulb or 2?

As it is, I don't see any reason to think B. nodosa plays any part in this hybrid. The leaves are way too broad unless B. nodosa is at least 3 generations back, just one of many reasons. What I do see is an obvious Rhyncholaelia (Brassavola) digbyana hybrid - and one possibility is Rhycholaelia Aristocrat (Rl. digbyana x Rl. glauca). Multi-floral spikes or bifoliate growth would rule that out though.

No expert here, but my instinct is the same- not nodosa, but close up- even primary- digbyana. The Rhy. Aristocrat I've seen were a little rounder/heavier/greener than this one, though I don't know enough to dismiss that. I have an Aristocrat hybrid (x. Binosa) that is most certainly not it. For starters, the nodosa terete foliage carried through on it.
My first impulse is maybe was-Bl. Helen? (Rhy. digbyana x. C. tenebrosa) With that yellow lip and bifoliate growth though, I don't think so. Probably digbyana x. some red/yellow lip bifoliate hybrid. It is a truly lovely thing though, NOID or not!

Also no expert here but I can see a Rhynch. glauca in it. No idea what the other parent(s) could be though

pipsxlch - some one on FB suggested tenebrosa as well.

Tschimm - That is one awesome glauca picture!
