Bright, circular Fresnel-lens shaped light several times larger than Venus appeared and then disappeared after about 30 seconds

While admiring the beauty of the clouds this morning, a UAP appeared directly in my field of vision. I starte at it the whole time it, trying to detect and determine the nature of what I was viewing. It looked similar to a headlamp on a train and too bright to be a planet. I checked and there are no planets anywhere near this part of the sky at this time. It did not appear to move in any direction and the shape and intensity of light suggested some sort of in-place motion such as spinning or oscillating. After about 30 seconds or so it vanished. Morning sky was lightly cloudy and the light appeared to somehow be punching through the clouds. The sky lighting and color was in very high contrast to the object viewed. The spot was way too bright to be a planet, but the distance and size light intensity was wrong for it to be any kind of naturally occurring reflection of the sun.
Since the sightline is in the general direction of the US White House, I was curious and used a compass to get the direction of the sighting and plotted a rough trajectory to see where the vector would fall on Google Maps. My best guess about where I think the object may have been hovering based on what I saw, is indicated by the bold red arrow on the UAP_map_vector_2021-12-07_8-22-06.png image uploaded. The area highlighted is between the White House and Andrews Air Force Base. I worked as a lighting design engineer in a previous career which developed advanced knowledge of human vision, perception and psychology of seeing.
I don't seek out UAPs and this is the first time I have reported one. I am reporting it primarily because of perceived proximity to important Federal institutions.
