dark 5:20 pm – 4:58 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.

Seeing the ISS from Guwahati
Guwahati is at 26.2°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 5:27 pm until 4:55 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 Guwahati (0 in the evening, 4 before dawn). The best is on Wednesday 14 Oct at 4:26 am: it appears in the west-southwest, climbs to 55° in the northwest and sets in the north-northeast, at about magnitude -4.
The next pass over Guwahati is in 4 days: Monday 12 Oct from 4:23 am to 4:29 am, reaching 30° in the east-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.
