Red sky

Saw a beautiful slender crescent moon on my way to work this morning, it's been a dull grey day here.
I've had better days too :-(
Seeing the sky like this was a surprise, the sky looks like it's on fire, what you cant see is the beautiful structure in the clouds that i could see, iPhone camera really doesn't do them justice :-(
Sorry :-(
Two hints I've had that the sun is somewhere about.
Hope you've all had a good day
