Each time I've downloaded fresh TLE's for the ISS over the past few days their orbit seems to have increased by a few hundred meters. The TLE's on the Celestrak.com site differ from the predicted ones posted on the NASA site (which do not show an increase in height). They seem to boost their orbit in small increaments on a daily basis as long as the Shuttle has enough fuel to spare. This proves frustrating for people like me who try to figure out how the chances are to see a sun transit on the weekend when the ISS and Discovery are about to seperate. On each of the past few days I got different predictions.
