An ISS Marathon begins this week when the International Space Station will spend around three days in almost-constant sunlight. From 21st to the 23rd May, skywatchers can see the bright spacescraft moving overhead about two to four times each night.
A simple way to find out when and where the ISS will pass overhead near you is to go use the Satellite Tracker – just select the location nearest to you and it will produce a chart of flyby times (as well as any other visible satellites you can see).
