Sun halo

Time when the heart warms up immediately, when it feels nothing but awe - common or uncommon such a sight, it's a gift from Above.

How it's slowly dispersing after 20 minutes.

 According to Google AI Overview:

A sun halo is a ring or light that forms around the sun when sunlight passes through ice crystals in cirrus clouds. The ice crystals' hexagonal structure and the way they fall create the halo's shape. 

Here are some other things to know about sun halos:

• Color
  Sun halos are usually white, but they can sometimes have color. The most common type of sun halo is the 22° halo, which has a series of colored arcs with red on the inside and blue on the outside. 
  
• Visibility
  It's uncommon to see complete rings or arcs, but you might see parts of them in clouds. 
  
• Formation
  Sun halos are caused by light interacting with ice crystals in the atmosphere. The ice crystals are usually found in cirrus or cirrostratus clouds in the upper troposphere, but they can also float near the ground in cold weather.
