White-gold textured ellipsoid vectors past skyscrapers in daylight

I live on the 41st floor looking north and i noticed what i thought was a metal balloon floating towards the west but it was further so i thought it was like a bed sheet but it wasn't changing course so i watched it and it was about a mile from my location still moving westward and its altitude was about 380ft (figured using the building next to it) and it was shiny metal almost like white gold and it reflected the sunlight to shine about 4 or 5 times while i was watching at a pretty slow tempo compared to how fast it was moving - it continued west and increased altitude about 15/30 ft but stayed relatively level - I didn't see where its trajectory was coming from but it seemed like the same course. it didn't disappear irregularly but was out of sight maybe within 1.5 minutes. The entire time it did not exceed my current position in altitude - not trying to be too technical just trying to be accurate. It it was spinning it seemed to spin counterclockwise. I ! often see planes fly by and relative to the speed of a plane it was moving maybe 2.5x as fast. Ah the shape was difficult to resolve - I would say it was close to the dimensions of a fedex truck or shipping container. It was rounded though no sharp corners so its profile looked like a bar of soap without dimples or a puffer fish but if it was spinning then i dont know what shape it would actually be. It is also very windy today and the object didn't seem to be affected or make any overt sounds (and i can hear sirens at that distance easily). [currently there is a fire on the train tracks directly below where the object passed over and my internet was bad for a while but i really dont think they are related]
