Using observations between Apr 17 and 19 (including Peter Wakelin's splendidly
long arc), and allowing the perigee to fall as an 8th variable, I get:

USA 136 Cent r                  3.0 v
1 25035U 97068B   04110.54734700 0.00885927  00000-0  13951-3 0    05
2 25035  63.5280  28.3076 7167380 248.0719  26.0314  2.52166749    08

This is an SGP4 production.

Happy hunting!

P.S. The new China launch 04-12A (28220) is well placed in the late evening from
the UK etc.

David.
