Strange moving light spotted over Siddal, Halifax, England.

My girlfriend and l were watching out of the attic window one night,when we became aware of a bright light which suddenly appeared in the sky,resembling the shape of a star. The shape vered north descended and went west performing a zig-zag motion as from east to west before manoveouring of to the west and disappeared. The shape looked like a star when it appeared, was orange in colour and disappeared when clouds moved in. There was no sound audible and the event took approximately 30 seconds from start to finish, maybe less.
