All,

21:08 UTC I had only a 8 degr elevation pass first and used both TLE for analyzing the doppler frequency. Well, it seems my assumption was right - seems we have to change the TLE for PRISM to OBJECT J.

22:41 UTC After this second pass with higher elevation (32 degr) I am sure that PRISM is OBJECT J.

You can see the graphs here in my SatBlog: http://www.dk3wn.info/p/?p=2407
