Anyone know what this flare is in the top lefthand corner of the picture?

1$\begingroup$ For a reasonable expectation of getting an answer, information about where and when the picture was taken would be helpful. $\endgroup$– Organic MarbleFeb 28, 2019 at 19:44

$\begingroup$ I can't see a flare in that image at all. Can you provide links, and maybe the frames immediately before and after $\endgroup$– Rory Alsop ♦Feb 28, 2019 at 20:02

The ISS live feed uses the cameras of the HDEV experiment. This is a group of four cameras in a pressurized housing attached to the outside of the ISS.
The picture is from the forward-facing camera. What you're seeing in the top-left corner of the image image are a dust filament on the housing (red circle), what appears to be sunlight reflecting off a surface defect of the housing (green), and the edge of the housing itself (blue). The visibility varies with sun angle and brightness; they're not visible as I write this, but could be clearly seen shortly after the ISS came out of Earth's shadow.

$\begingroup$ Cool answer! I've just asked How is the atmosphere in the pressurized housing of ISS' HDEV cameras managed? Outgassing addressed? $\endgroup$– uhohMar 1, 2019 at 5:50
