The ISS is visible from Southern Spain this week. Use the chart below to find the best times and direction. For the best sightings go for the lowest Mag or magnitude number (-1.4, -1.6, -2.0 etc) the lower the number the brighter it will be, Also go for the highest Maximum Alt figure (Altitude) 90 is directly overhead, 45 is half way up the sky, anything above 25 is good. By clicking on the date of the sighting it will take you to a map showing its route across the sky,

The International Space Station photographed in March 2009 is now the largest structure ever to be built in space.

It is travelling at 17,000mph at a height of about 350km. It circles the Earth every 90 minutes.

It is now bigger than a football field and can easily be seen from Earth. The usual crew of three astronauts has now been upgraded to a permenant crew of 6 astronauts. The final sections are due to be fitted before the end of 2009. Almost all of the sections were delivered to the ISS by the space shuttles and connected to the ever growing station by astronauts carrying out numerous space walks. As the ISS has no external lights of its own then it can only be seen about an hour after sunset or an hour before sunrise when there is enough light from the sun shining on it but it is dark on Earth where you are standing. Some people have reported being able to see it even in daylight now that it is so big!
