    The mid-point of the arc was near the time of predicted maximum SRP (Solar Radiation Pressure) effect on the mean motion; from here,
    the rate of decay will decline, and will become negative near day 02357 (2002 Dec 24). It will likely take until mid-January to
    accumulate an arc sufficiently long to reveal the negative rate of decay.
