The latest elements for Lewis are:
Lewis                                            201 x 190 km
1 24909U 97044A   97270.58776880  .04852244  25974-5  12180-2 0  1506
2 24909  97.5486 168.9461 0008961 169.3228 190.8307 16.28953916  5637

This shows it running 30s early with respect to the SatEvo evolution I
posted yesterday. There has been a modest increase in geomagnetic
activity but not (yet) the storm conditions which some had predicted.

My latest analysis brings the decay forward to about September 28.5.
