I had parked my vehicle at our assigned parking deck. it was a day after the storm so the sky was cloudy, and i decided to take some pictures with my phone. since i was facing the sun, i took the pics not really looking, and when onto class. i noticed the object after i had posted the picture on my instagram account. i zoomed in and tried to to make out what it was. it's a round, dense circle. i even tweaked the settings, after zooming in, so as to get better resolution on the object. i have never seen anything like it in all the years i've been photographing.
