Not insinuating or inferring anything here-merely an observation. I've watched the Sun video several times, paused it and tried (as best as possible) to advance it frame by frame. At 1.20 and 2 or 3 tenths (at a guess), just outside the red circle at about 3 o'clock, is a white dot which then enters the red circle seemingly heading towards the tail. That same white "dot" then seems to be spat out initially to the right but them starts heading rapidly across the screen right to left. At first I was convinced it was just an insect flying close to the camera but now I'm not so sure. What started as a dot now seems to become a very regular (rectangular) shape as it travels across the screen
