Looking for the Belt of Venus

I found this article on the Astronomy Picture of the Day website http://apod.nasa.gov/apod/ap100404.html so I've been looking for this effect. I took this picture from Ravenglass campsite. You can see the Sellafield chimneys in the rosy glow behind the tent.

I'm wondering if the pink band with the grey layer below is the Belt of Venus. I had always thought that the grey was just distant cloud. Research tonight suggests I should be able to see the effect in all directions, not just in the direction of the sunset, so I'll look again.
