Without realizing it I had captured a picture of a ufo while out smoking with a friend

I was walking near the local mall with my friend and we were going to our favorite smoke spot when I looked in the sky and thought the sky was pretty so I took a picture so I could draw it later which isn’t uncommon since I’m an artist. Later that night after I was sober I noticed a white glowing saucer shaped object in the sky in that picture. It wasn’t a lense flare, drone, plane, bird, or helicopter and when zoomed in it looked suspiciously like one of the hundreds of other ufo pictures. I’m curious as to what this thing I accidentally caught while walking to go and smoke was.
