My Thoughts

Just to be clear, this seems to go beyond the physics of the standard sunset. To me, there seem to be 3 atmospheric conditions that are playing their part in this phenomenon. The first 2 will give you the standard sunset with its beautiful colors.

Rayleigh Scattering.
The longer distance light travels along the Horizon.
- This enhances Rayleigh Scattering and gives the colors of the sunset.
???
- Either this enhances Rayleigh Scattering more along the horizon (enhances #2)
- Or it's a separate phenomenon completely
  - When combined with #1 and #2, allows people to view the surface of the sun without protection!

More Background Information

I have seen this phenomenon a few times before in Seoul.
- Phenomenon never occurred in the US in my hometown for me
  - Hometown is farther north than Seoul.
  - Harbin, China would be a similar latitude.
I have never seen this phenomenon during the winter.
- It's possible it has happened, but I didn't see it!
- It's only occurred in the Spring and Summer for me.
While the afternoon was thicker in air pollution, I believe around sunset the air pollution nearby was much more clear.
- Around this time (if UTC conversion were correct), there was a thicker air pollution mass around China and the northern part of the Yellow Sea.
  - Sun sets in the West, and any air conditions to the west could affect the sunset.
  - Is that in line-of-sight? Did the air pollution reach higher in the atmosphere around China? With line-of-sight, that would be around 10 - 60km in the air over the Yellow Sea and China.

Analysis

With #1 and #2 directly above, the longer distance that light travels along the horizon during (1) the sunset and (2) the winter in the Northern Hemisphere doesn't seem to play a big part. Otherwise, I should see this a lot in the winter around sunset. I don't, and I never have.

Can air pollution be clear nearby, yet block all the bright light rays farther away?

Photo

Here is a photo that can help show the conditions that were present at the time. Please note that the sun appears much brighter in this picture than it was in-person. The sun was actually really dull red. As you can see, there were clouds, but I am trying to find maps that show the cloud coverage around that time, as I don't believe it was thick.
