I use several web sites to search the visible passes of the ISS over a given location.
Then I calculate the Sun elevation as seen from the ISS and I get surprisingly low elevations; for example, I get ISS magnitude= -3.8 and Sun elevation at the ISS= -19.9 deg.
I suppose that the atmospheric refraction is very high, but what's the lowest Sun elevation to consider the ISS outside the Earth's shadow?
Thank you
