Waves in the sky: cirrus cloud formation

On my cycle home from work a couple of days ago I was aware of the unusual clouds above me. I knew there'd be a good vantage point when I'd turned off the main road flanked by houses and got among the fields. I was hoping that the cloud formation would last long enough for me to get there, and, fortunately, it did.


I think this is cirrus cloud, but there's nothing exactly like it on the page of cloud types on Wikipedia. Confirmation, anyone?


By the time I'd cycled a mile or so further the clouds had gone and the scene was lit by a low orange sun.
