Bright object over downtown (East) Denver is observed twice, then the same thing appears in the West

Approx 6:30 PM, I am riding in the passenger seat with a friend on Sheridan Ave due North. I look out the passenger window to the East and notice a large, bright circular object with a bright corona in the sky over Downtown Denver. There are no colored lights on the object to signify a conventional aircraft. When observed through a phone seems to be either changing shapes or is emitting orbs that seemingly change the object's shape.

We take a left turn at an intersection to head West and during this time that we are turning the bright object vanishes from the sky.

Approx 30 minutes later we had returned home from errands and, as we approached the door to the house, I notice the same bright, circular UFO hanging in the sky to the East. A seemingly conventional aircraft (read: helicopter) in the same area of the sky seems to be approaching the circular object, at which point the object promptly vanishes from the night sky.

I run inside to tell my friend who had already gone inside to put away items. We both return outside and observe either the same or another circular bright object to West, low on the horizon, seemingly barely above the mountains themselves. We observe the object to the West for approx 3-5 minutes before returning inside.

5-10 minutes later I returned outside to no anomalies visible in the sky.
