dark 7:25 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.

Seeing the ISS from Saint George
Saint George is at 37.1°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 7:35 pm until 7:09 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 Saint George (0 in the evening, 4 before dawn). The best is on Wednesday, Oct 14 at 6:54 am: it appears in the southwest, climbs to 74° in the south-southeast and sets in the northeast, at about magnitude -3.5.
The next pass over Saint George is in 5 days: Monday, Oct 12 from 6:53 am to 6:58 am, reaching 21° 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.
