FWIW, using Lake Kickapoo Texas SPASUR radar fence: ISS crossed at 17:40:10 EST Fri Feb 25, 2011 (TLE predicted 17:40:44) STS crossed at 18:08:34 EST Fri Feb 25, 2011 (TLE predicted 18:06:49) So, STS was 28:24 behind ISS for this observation. The times were taken from spectrogram of recorded signals so I guess I can claim that this is a visual observation of sorts. STS TLEs were from NASA public web page. Interesting to track STS closing on ISS by getting snapshots of time of observation. One more opportunity for SPASUR observation before docking. ISS and undocked STS (on orbit 23) should pass through Lake Kickapoo fence at ranges which are conducive to good signal reflections on Feb 26 in the 01:40 EST to 02:00 EST time frame.
