Orange round lights

Ok basically, i was at a friend's new year's party on 31/12/08. We were in the back yard launching some fireworks. After we launched a few rockets, my friend suddenly said.. "whats that!" we all looked up and we saw an orange/amber circle slowly moving above us, must have been about a thousand feet up. I didnt think anything of it at first, but i remembered my other friend Dan said he saw the same orange light, but 4 of them moving slowly over Ferndown. I then also remembered about a time 2 years before, where i saw another exact same light while standing on my road.
