Long Description:

Thanks to Bear&Fox and all the other South African Geocachers that helped us out with this Waymark.

The ISS is by far our favorite satellite, we watched the first launch and have seen it hundreds of times since then. On the 31 May 2007 we did something completely new and collaborated with a caching team, Bear&Fox, in the Western Cape to see the ISS on one of its passes. In fact we would have seen the ISS simultaneously for roughly a minute too.

The ISS passed Capetown at approx 18H51:30 and passed us in Johannesburg, over 1000km away, 3 minutes later at 18H54:29, a distance that takes an airliner well over an hour to accomplish.

This is a 4 second exposure of the ISS moving through the clouds on the 31st

Some interesting stats from the pass are:
The ISS reached 10º at 18H49:38 at an Azimuth of 228° - Range = 2 127km
The ISS reached 47º (It's max alt) at 18H54:29 at an Azimuth of 321º, its magnitude was supposed to be -1.0, but it gave a little flare of about a -3 for two seconds before returning to its -1 magnitude.  - Range = 455km
The ISS entered the Earths shadow at an Azimuth of 345º at 18H54:57 - Range = 504km
The total distance that the ISS covered was 1246.14km in a total time of just under three minutes.
