Circular upside down bowl shape with lights

I remember this date well because my aunt was watching us while my mom was at the hospital in labor with my sister. I was sitting on the couch in our living room watching TV when in my peripheral vision I noticed it was night time in the front yard and day time in the back yard. I knew it was actually night time so I got up to look in the back yard. I stepped outside and looked up. Hovering over our backyard was a circular UFO/spacecraft. It went up underneath...kinda like an upside down bowl shape with multiple rows of lights inside. The light that came from it didn’t look like a spotlight, it was just as if daylight existed under it.
I heard my 5yo brother say “oooooo, pretty lights” and that’s when I realized he had followed me outside. We then started yelling for my aunt. By the time she came outside it disappeared.  No noise, no wind, nothing. Just gone. I was about 9 years old at the time. My brother 5. He still remembers it in detail to this day as well.  I searched on here to find other sightings around the same time.  I’m very interested in the other MI sightings in this same month as we may have seen the same thing.  I put “Commerce Township” but back then I think it was technically “Union Lake, MI”
