Tracking the ISS

It was cold at the wharf, and there weren't many others still there (just the diehard fishermen) and us - waiting for the International Space Station to transit overhead. David had a new iPhone app which showed us it's intended trajectory. And sure enough at 6:12PM, it rose in the SW and tracked quickly across the sky before disappearing in the North about 5 minutes later. It was actually quite bright and very easy to follow (magnitude -3.2). You can imagine those huge solar panels reflecting light back to earth. Just another of the crazy things we do in Derby!!
