Times are in Western European Summer Time (Europe/Lisbon).
Every row is a visible pass, and its times are the ends of the visible window: while that window lasts, the Sun is at least 6° below the horizon (nautical twilight or darker), the satellite is in sunlight, it is at least 10° above the horizon, and it is magnitude 4 or brighter.
How bright a pass gets is predicted from the satellite’s standard magnitude, how far away it is and how much of its sunlit side faces you. It ignores flashes off flat surfaces and the haze that dims anything low in the sky.
Times are computed for the city centre and may differ by a few seconds elsewhere in Porto.
Pass times computed on Sep 18, 2026, 10:00 PM from Space-Track orbital elements, then 16 hours old.
