I was looking this morning as well, but couldn't find them.
Analyzing the doppler shift indicated the pass was 50s later than the 
pre-launch TLE's indicated (for the 8:30 UTC pass over the UK)
I updated the pre-launch TLE (by adding 50s to the Epoch time, and 
re-calculating the checksum) and the doppler correction on the following 
pass was much better.
I guess the orbit may be slightly higher than predicted, resulting in a 
fractionally longer orbital period.
73s, Simon. G7WIQ
