dark 7:06 pm – 7:16 amMagnitude 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
1 visible pass in 8 nightsYes · 6:18 am, look south. Tiangong orbits about 386 km up, tilted 41.5° to the equator. It looks like a bright, steady star gliding across the sky, fainter than the ISS but easy to see without a telescope.

Seeing the ISS from Dún Laoghaire
Dún Laoghaire is at 53.3°N. 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 7:22 pm until 7:03 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 is 1 visible pass over Dún Laoghaire (0 in the evening, 1 before dawn). The best is on Thursday 15 Oct at 7:01 am: it appears in the south, climbs to 15° in the southeast and sets in the east-southeast, at about magnitude 0.
The next pass over Dún Laoghaire is in 8 days: Thursday 15 Oct from 7:01 am to 7:05 am, reaching 15° in the southeast.
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.
