at about 7 am in the morning, i along with a number of my co workers observed this very bright light in the shape of an oval hovering in the sky close to the nickel rim south mine, which is behind the sudbury airport. a few described a second smaller light descending down into the larger oval light. i did not we that. i could just about make out a line running from the center top to bottom as it was motionless in the sky. i got dressed into my work cloths and went back out side to the parking lot with my smartphone and recorded the object for a minute or so. it was a clear sunny sky and the object was very white bright. it was approximately, a half mile from the sudbury airport facing south west from my position. i knew it wasn't venus or that it could be a weather balloon being so close to the airport. after a while we went in for our morning briefing and then proceeded out to the head frame . it was at that time i noticed that the object had shifted position and was now more north west facing. this was witnessed by most of my crew
