Iridium - a system of satellites hanging above our head at an altitude of 780 km. In addition to the sensational
collision on February 10, 2009, the system is known for the fact that with the help of calculations one can observe an interesting effect - the reflection of sunlight from satellite antennas.
The reflection is seen quite well, sometimes it is possible to observe the phenomenon during the day, but at night it is naturally more colorful. It is natural to load oneself with calculations reluctance, so good people created a
service with the help of which it is easy and simple to calculate the time of appearance for the next 48 hours for their coordinates.
