About this image

A different take on an ISS pass photograph. This image shows the ISS passing very close to the bright star Betelgeuse in Orion on the night of 3 April 2017. The space station was around magnitude -3 and the star is around magnitude 0.5.

Very nice - nearly an occultation.

What gives rise to the subtle brightening and dimming of the ISS trail?

Thanks. I think the slight variations in brightness could be due to the slight changes in orientation of the station as it passes over. Another possibility would be high level, thin cloud.
