Lewis decay imminent

The latest elset for Lewis is:
Lewis                                            175 x 163 km
1 24909U 97044A   97271.20048492  .10738351  27111-5  99139-3 0  1545
2 24909  97.5442 169.6720 0009273 204.6093 155.4671 16.38767649  5734
which shows it running 5.7s early with respect to the SatEvo evolution I
posted 16 hours ago.

I predict the following final orbits to decay:
Lewis                                            166 x 160 km
1 24909U 97044A   97271.26147994  .18692969  26979+0  13308-2 0 91514
2 24909  97.5422 169.7499 0004702 160.7830 199.2346 16.41121125  5742
Lewis                                            158 x 153 km
1 24909U 97044A   97271.32240943  .26256710  65581+0  10431-2 0 91514
2 24909  97.5410 169.8229 0003797 160.5287 199.4858 16.43802251  5757
Lewis                                            146 x 143 km
1 24909U 97044A   97271.38321594  .48213321  27402+1  84179-3 0 91519
2 24909  97.5396 169.8962 0002594 160.2737 199.7363 16.48031816  5766

Decay may occur near the northbound equator crossing following the final
elset above, at about 10:39 UTC at 3 deg E longitude on a track taking
it to the W of Madrid in Spain and over SW Ireland at 10:52 UTC.
