FYI, I encounter observations of the ISS at times when I am out stargazing. My log shows this entry for 25-April-2020 when I viewed Mars, Saturn, and Jupiter in early morning sky. That was a fun observation!
[Observed 0445-0545 EDT. Sunrise 0616 EDT. I used 10x50 binoculars this morning and enjoyed views of Mars, Saturn, and Jupiter along the ecliptic. Fields were very wet from rain yesterday and ground fog in the fields. Some deer were out nearby and snorted at me, they walked off and ignored me after a bit. Stellarium 0.20.1 showed the ISS moving from SSW to E in the sky chart view. I viewed the ISS starting about 0529 EDT, low in SSW moving across to the E. The elevation angle was higher than Jupiter and Saturn near the ecliptic when the ISS passed the planets this morning along the ecliptic. I tracked the ISS from 0529 EDT until 0536 EDT when it disappeared behind a low cloud bank to the east. The ISS orbiting at 8 km/s in 7 minutes, traveled some 3360 km above the round Earth this morning while I watched (2100 miles). Earlier, near 0516 EDT, an equatorial orbiting satellite passed by moving west to east and about apparent magnitude 2.0. The ISS was as bright or a bit brighter than Jupiter when it passed above Jupiter and Saturn in elevation angle. Jupiter mv -2.31 this morning.]
