Orange Ball of flame/light?

My husband and I were out having a smoke last night (21/12/2009) around 9.40pm when he pointed out an orange ball in the sky.  We thought it was a plane but realised there was no sound, no flashing red or white lights but just a solid glowing orange light.  I was worried as I thought maybe it was a plane on fire but there was no kind of tail or afterglow to say it was moving.  We should have seen that as there were clouds that went over it for a second.  It seemed to hover in the same place for about 10-15seconds before moving a just little bit and then disappearing alto
