You make some very interesting points regarding the sun halo and you could be right but I will still argue that it could be Saturn because there is more than one 'halo' and it could symbolise rings of Saturn rather than a sun halo. In a still it looks like a halo but in the video there is a lot of movement and a lot of rings/halos.

I'm glad you mentioned clouds because I was going to question whether there would be clouds as far up as the sun. They do seem to have the appearance of clouds.
