How to spot it

Look for a bright, fast “star” that doesn't blink — the ISS outshines everything except the Moon and Venus.
It moves west to east, crossing the whole sky in 3–6 minutes.
Evening and pre-dawn passes are the visible ones — the station must be sunlit while your sky is dark. 1 good window in the next 3 days (marked ★).
Madison sits within the ISS's orbital band, so it can pass nearly straight overhead — those 70°+ passes are spectacular.
