We are observing a phenomenon over Tainan City. It's like a perfect circle over Tainan City, a perfect circle in the sky. I would like to know what it takes what's a naturally occurring phenomenon that can create a perfect circle in the middle of the clouds. A perfectly circle glaring in the clouds over Tainan City, I don't know what it could be.
