Yes, it is possible to see how the International Space Station flies over planet Earth , not only because it is the third brightest object in our sky after the Sun and the Moon, but because NASA has provided a service that warns us personally of the passage of the ship on our domicile.
We just have to register on the website "Spot the Station", and enter the country and region in which we live to receive a text message or email as an alarm at the precise moment in which we must scan the sky. Unfortunately, it is not possible to configure 16 alarms that warn us of the 16 times that the ISS passes over us a day, but we will have to settle for one in the morning and another in the evening. This is because to see the station, it is necessary for sunlight to reflect off its large panels, but its light intensity only allows us to detect this brightness just before dawn or after sunset.
These alerts will also come to us depending on whether there is a real opportunity of sighting , since many times its elevation does not reach 90 degrees above the horizon and it is difficult to see it. On the other hand, the station orbits at an inclination of 51.6 degrees, which means that inhabitants of latitudes above 51.6 degrees will never see the ISS pass overhead.
In one of those optimal moments, which happen a couple of times a week , and in case we do not suffer from severe myopia, we will be able to see the International Space Station crossing the sky from west to east as if it were a propelled star.
