I stepped outside for a smoke. It was absolutely quiet and I spotted something moving above me what seemed translucent like a cloaking device but was not invisible it was like a dark haze and was large in size no lights and was either circle or triangular and made no noises. it was moving fast south. I grabbed my phone to shoot a video but it seemed gone by the time I got my video going. I then looked around the sky line another 2 mins and nothing. I stepped back inside and reviewed my video and happened to catch a 1 frame glimpse of the object 44 second into my 45 second video. That one frame the only moment it was visible as a glow admitted from below the object. but it atleast shows that something was really there in the skys that I saw.
