UFO Sighting in Armagh, Northern Ireland on September 12th 2015 – very bright teardrop large object with tail

Watching television at dusk, windows open and object traversed across sky/field of view in a second or so, very fast, very incandescent white large ball with trail traveling west to east above tree line below low cloud. Thought `wow what is that, wish that was slower, ran out but it had gone`.
