    Epoch Date Age Analysis is compiled twice weekly by Satellite
    Tracking Houston- http://sattrackhouston.com The next compilation
    of these data will be Tuesday, 29-Oct-2002, at noon CST, 18:00 UTC.
    The epoch date is the time at which the orbital data (Keplerian
    elements) have been calculated.  Satellite names are not listed
    if greater than thirty-five (35) in a category. US Daylight Savings
    Time (Summer Time) ends at 2 a.m., Sunday, 27-Oct-2002.
