When will the International Space Station pass over Sofia?

ISS stands for the International Space Station — the largest and brightest human-made object in orbit around Earth. Passes over Sofia above 10° in the next 10 days: 59. Of those, visible to the naked eye: 20.

The next pass of the International Space Station over Sofia is on Tuesday 25 Aug at 02:00 local time, reaching 11° above the horizon. The next pass you can actually see is on Tuesday 25 Aug at 03:34 (81° above the horizon).

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 ★).
Sofia sits within the ISS's orbital band, so it can pass nearly straight overhead — those 70°+ passes are spectacular.
