UFO Sighting in McKinney, Texas on 2020-10-30 20:51:00 – Arched cloud shape starting around the moon then descending below

I came out around 8:50pm on oct. 30, 2020 & looked up at the moon & observed a cloud like shape arched around the moon. i went in to get my cell phone, then spent a couple minutes attempting to stop the flash from coming on automatically. at 8:54pm i captured these 4 images wherein the arched cloud had descended to below the moon at this time.
