I was at work looking to the western sky because the sun had set and the sky was cloudless. I had been looking at the sky all summer and fall for anything peculiar because of the prospect of sighting anything phenomenal due to seeing planes chem trailing in the morning and night, just on the horizon, as if they were trying to conceal something. Then as if out of nowhere a huge pyramid out in space appeared. It had to be, I don't know, at least the size of probably a hundred miles in height and width. It was hard to tell because it was very far from the earth, possibly thousands of miles away but it was hard to tell because there was nothing to give it any kind of scale.To me it looked planet like because i have never scene any flying object that size ever.The object appeared very very far away but still huge. I was stunned because it wasn't there,then it was there, then it was gone. I took two pictures of it before it disappeared. There were about 20 or so people around, but no one else saw or said anything so I said nothing. The whole experience happened so fast that I almost couldn't believe it. The thing is the pictures are from my phone so there crappy, so I'm hoping you will have the ability to make the photos better.
