Pursuant to the question Does the ISS have zenith-facing windows? to which the conclusion (in my opinion) is that there may be a window that provides an oblique view that might include the zenith if you hold your head to the side, I'd like to ask about what looks like a window in what I believe to be an ISS-docked Soyuz spacecraft.
What direction does this window face? In this case at least, facing-direction means the direction of the vector normal to the window's surface.
below: screenshot from a recent Roscosmos tweet of cosmonaut Sergey Prokopyev (presumably) talking about the lead detection and repair and showing an ULD? (I can't speak Russian, but presumably this is correct.) Translating the text using Google:
"Friends, I decided to shoot a video to answer your numerous comments and dispel rumors. Everything is calm on the ISS! "
The window in question is seen to the right of Prokopyev's head, is facing "upwards" in the photo, appears to be sunlit, and I estimate it to be around 12 to 16 cm in diameter.
russiatag in hopes of getting this double-checked by someone who speaks Russian, thanks! $\endgroup$
