Is that a 'UFO' or just a really pretty ring of light?

Stomper Charles was in a flight heading to Singapore from Taipei and was randomly snapping photos of the view outside the jet he was in at around 4pm on Tue (Oct 18).

As Charles was looking through the photographs, he noticed one of them shows a bright oval shaped object near the top of the photo.

He enlarged it and discovered that the object radiates a glow around it.

Charles do not know for sure what it is but in his opinion, it looks like a 'UFO'.

What do you think it is?
