Highly reflective Cylinder object seen on the William Floyd Pkwy., Long Island

Traveling South on William Floyd Parkway in Mastic Long Island. We were about 2 miles north of Brookhaven laboratory. It was late in the afternoon about 5:45 PM. The sun was glaring on my right side I saw a flash and noticed a shiny cylinder shaped object hovering stationary in the sky. The object was extremely reflective and seemed to reflect the sun off the object. The object did not have writing or lights on it. the trees going by on the right side made it difficult to get a long view of the object because it was at a lower height then an airplane would be.
I lost sight momentarily behind the trees but located it seconds later and then it was gone.
