A fist at arm's length covers about 10° of sky. It looks like a bright, steady star moving quickly, with no flashing lights.

How to spot the ISS
Go outside a few minutes early and let your eyes adjust. Face the direction shown and look for a bright, steady light moving smoothly across the sky. It doesn't flash like a plane, and it crosses the sky in a few minutes. You don't need a telescope or binoculars.
Why only at dusk and dawn?
Satellites don't shine by themselves. They reflect sunlight. You can see one when your sky is dark but the Sun is still lighting it up high above you, and that mostly happens in the hours after sunset and before sunrise. A pass can end in mid-sky when the satellite enters Earth's shadow.
How to read the sky map
The map is the whole sky above you, with north at the top. The centre is straight overhead and the outer edge is the horizon. Green dots are high enough and lit by the Sun in a dark sky, though the fainter ones need a dark spot away from street lights. Grey dots are too low, in Earth's shadow, or lost in a bright sky.
How accurate are the times?
Times are calculated from the latest published orbit data, using the same standard model other trackers use. They're usually right to within a few seconds for the next day or two. The ISS sometimes adjusts its orbit, so check again on the day for passes further ahead.
