no visible passesMagnitude is an estimate (lower = brighter; the ISS is usually between −1 and −3, brighter than any star). A pass that ends high in the sky ends because the station enters Earth's shadow, not because it sets. How we compute this.
Tiangong, China's space station
4 visible passes in 8 nightsNo visible pass of Tiangong over Darwin tonight. Next: Monday 12 Oct at 7:37 pm. It orbits about 386 km up, tilted 41.5° to the equator, and looks like a bright, steady star gliding across the sky.

Local time. Brightness is a rough estimate (±1 magnitude; lower is brighter). How we compute this.
Seeing the ISS from Darwin
Darwin is at 12.5°S. The ISS orbits at about 420 km, tilted 51.6° to the equator, so it passes within sight of this latitude on many nights. Tonight the sky is dark enough from 7:05 pm until 6:03 am. You can only see the station when it is still lit by the Sun while you are in darkness, so passes come in the hours after dusk or before dawn.
Over the next 8 nights there are 4 visible passes over Darwin (2 in the evening, 2 before dawn). The best is on Saturday 10 Oct at 5:09 am: it appears in the northwest, climbs to 75° in the northwest and sets in the north-northeast, at about magnitude -4.5.
The ISS looks like a steady, very bright star moving smoothly across the sky in a few minutes, with no blinking lights. It needs no telescope. If the times above say it fades out high in the sky, it has entered Earth's shadow: it disappears in a few seconds.
