The last three elsets show the perigee to be decreasing and the apogee
increasing, all due to luni-solar perturbations...

I calculate that the perigee will be forced down to 2000 km by next
February 24 and to 1000 km by May 5, with little or no change in the
mean motion during this period. I expect decay to occur about June 2 by
which time the inclination should also have decreased to 50 deg.
