UFO Sighting in belfast, on October 29th 2015 – snaping clouds, upon enlarging this is what i found?

I was outside my back garden taking photos of cloud formations, then after I put them on my pc, in two photos I noticed a little spec on two frames,so I enlarged them to find the oddest things! I went back out straight away but they where gone. I have not manipulated photos at all, just enlarged them. the night before, clear night, I observed a small starlight coloured object, it was way way up in the atmosphere, so I grabbed my very strong LED TORCH aimed at the ufo and flashed twice slowly at it and it "IT GLOWED BACK AT ME IN A BEAUTIFUL STARRY BLUE!" next thing it disappeared.
