Yesterday, ISS/Discovery raised their orbit slightly (0.87 km). I am reasonably certain this had not been in the flight plan, so I suspect it was a collision avoidance manoeuvre. USSTRATCOM's elements will take a while to accurately reflect the effects of the burn, so be extra careful using their elements or predictions made by services that use them. This NASA page has the correct present elements, as well as predicted future elements that take into account all planned manoeuvres: They are on this web page (for shuttle hit the red icon; for ISS, hit the green one): http://spaceflight1.nasa.gov/realdata/elements/index.html Here is the present ISS/Discovery orbit, provided by NASA: 1 25544U 98067A 05212.34066944 .00016071 00000-0 12697-3 0 9001 2 25544 51.6460 34.8079 0001945 192.3100 167.8015 15.71759745 22632 The same site offers this web page of predictions for major cities around the world, generated using the above elements, so it should be very accurate: http://spaceflight1.nasa.gov/realdata/sightings/cities/index.cgi Later today, I intend to post information regarding the potential to observe ISS and Discovery in close proximity to one another, after they undock, now scheduled for August 6 UTC.
