>I just watched a favourable pass of the tether, and it seems to have a 
>waviness over the bottom third, although it is only a couple of 
>slight undulations over that length. 
>From the top down it is straight for 12km? then goes forward, then back, 
>then a sharp kink forward right on the lower end probably only in the bottom
> 100 - 200 metres. This lower kink looks a bit like the bright point on the
>top end initially, but close inspection with the 10 X 50s shows it clearly.
>The tether was easily visible naked eye despite the Full Moon, and seems to
>be following a bending routine similar to the SEDS tether of 1994, which 
>also developed a kink forwards on the lower end.
>Any suggestions for this kinky behaviour? 
>The Shuttle followed a similar path about 6 minutes later.
