    But lunisolar perturbations are barely noticable at this apogee height.
    Drag is building up smoothly, but faster than I thought, partly because
    the perigee is getting closer to the equator (AOP now 200 degrees,
    early 2005 208 degrees). Though the rate is increasing, it will be
    close to the equator almost till the end.
    But perigee will remain at the night side, where drag is lower.
    Simple SatEvo run predicts decay mid-November.
