I’m trying to understand when the picture was taken. The hints in the description don’t seem to gel well.
“During the early morning hours” could mean early as in shortly after midnight, or early as in just before dawn, a range of about 6 hours.
The total eclipse phase “had begun before moonset.” Moonset on May 16 in France occurred at 6:21 am, so that works.
The ISS was “still in sunlight”, which makes it sound like after sunset rather than early morning. Maybe that’s where my confusion lies. The ISS is, obviously, outside of the Earth’s shadow and in early morning sunlight, but not “still” in it.
One final puzzle… the streak of the ISS path is not exactly smooth, but given the “series of consecutive images” taken over 5 minutes I would have expected dots or multiple short streaks, as we’ve seen many times when a satellite crosses through a sky image. And that streak is heavily pixelated, implying some, er, adjustment done in processing. So I’m wondering how exactly the streak was produced.
I’d ask all this of the photographer, but the link in his name under the image doesn’t work.
