Orange sphere halo silentI had just parked my car up in the public car park which is about 5 minutes walk to my house.There was a firework display going on about 2 miles away in a public park.as I crossed the road to the street that runs behind my house I saw an orange light, about 50 ft in the air floating across the tops of houses and a school, I assumed it was a firework,but it did not behave like one..It maintained the same colour,made no sound and carried on for about a minute.Another man was on the other side of the street and I pointed it out to him, we both stood and watched it getting further away till it dissapeared over a hilltop.It was dark orange with a light orange halo around it.It made no sound and moved slowly and deliberatley.
