Had phone camera on zoom, looking at clouds through glass door. saw object, dark, with reflection, silver at top, possibly with an aura. seemed to be flat disk shape, hovering at maybe a 45 degree angle from horizontal. it got slightly larger, as though approaching, but seemed quite distant, even at closest point. it then began to abruptly move in a westerly direction, then straight down. i did not see it land because it went below my field of view.
