Bright crisp days often mean clear dark skies at night.
For the next few days it may therefore be possible to spot the glowing space station as it passes above Chester in the night sky.
The ISS, which appears as a bright glowing object, looks like a fast-moving plane or star moving across the horizon usually from the west.
It is currently habited by a crew of six including British astronaut Tim Peake.
Major Peake, 43, blasted off in his Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan together with Russian crew commander Yuri Malenchenko and American Nasa astronaut Tim Kopra in December last year.
He is expected to stay on the station until May.
The ISS orbits at a height of about 264 miles, traveling around the earth 15 times a day.
The ISS has been in space for more than 6,000 days, during which time it has completed around 100,000 orbits of Earth, and has been continuously occupied for more than 13 years
To see it look south or west at night at the time given below.
What you're looking for:
It pretty much looks like a bright star or fast-moving plane, usually from the west or south west.
It has no flashing lights and doesn't make a sound so that's how you can tell the difference between it and any aircraft in the sky.
