My orchid in full flower, again

I'm delighted to show my orchid plant in full flower. This is the third time I have had it in flower since I was given the plant two years ago.It is by far the best array of flowers I managed to produce.

I've been trying to learn how best to look after, feed, water and generally nurture orchids in the home. I have another l=similar plant which sits just beside this one in my study close to the window, but which has no flowers at all at the moment. 

I'm hoping these flowers will remain on the stem for a few more weeks, and I'll try to do a closeup of one of the flowers to show the beautiful detail and colours they offer. Maybe manana.
