Where to look
Look for a brilliant star, brighter than any other in the sky and that is the space station.
The station will appear at 11° above NW at 6.25pm, and disappear at 15° above SE six minutes later.
It will reappear again briefly at 11° above WSW at 8.03pm.
Residents do not need a telescope to spot the station, because it is travelling so fast it is easier to snatch a glimpse with the naked-eye.
While the ISS has been visible for the past week, tonight represents the longest viewing time available.
Space station facts
The space station orbits the Earth every 90 minutes as it collects data from around the globe.
It is longer than a rugby union field and has an international crew who live and work onboard.
