You observations are correct.

The old tle was:
1 21147U 91017A   07357.17849791 0.00000090  00000-0  13107-4 0    09
2 21147  67.9969  31.3871 0006500 276.8379  83.1620 14.75743416    01

The current tle is:
1 21147U 91017A   08012.71441514 0.00000080  00000-0  11637-4 0    04
2 21147  67.9959 336.6207 0006500 254.9251 105.0748 14.75794079    06

So the mean motion changed by about +0.000500 on Jan. 6.
This is not the first time that Lacrosse 2 has performed a small maneuver.
