Here are new NROL-47 elsets, for launch tonight (11 January 21:00 UT):

First, taking the launch azimuth at face value (resulting in a 108.6 degree
inclined orbit), for two altitude variants, one ~1500 km orbital altitude and
one for a FIA-like ~1100 km orbital altitude:

NROL-47 1495 X 1505
1 70000U 18999A   18011.87500000  .00000000  00000-0  00000-0 0    07
2 70000 108.6398 114.0196 0006347 166.4011 308.2684 12.41559515    04

NROL-47 1100 X 1110
1 70001U 18999A   18011.87500000  .00000000  00000-0  00000-0 0    08
2 70001 108.5831 114.0196 0006682 166.4011 304.1188 13.41149813    09


Second, two more altrenative elset (for the same two altitude variants) that
assume an inclination-changing manoeuvre into a 123.0 degree inclined FIA-like
orbit upon first nodal passage:

NROL-47 ALT 1495 X 1505
1 70004U 18999A   18011.88958333  .00000000  00000-0  00000-0 0    08
2 70004 123.0000 114.0319 0006347 179.9597 359.9483 12.41559515    04

NROL-47 ALT 1100 X 1110
1 70005U 18999A   18011.88648148  .00000000  00000-0  00000-0 0    09
2 70005 123.0000 114.0483 0006682 180.0080 359.9441 13.41149813    00
