    I use an old dos program - Mr. Orbit for my satellite predictions. I ran
    the numbers for Mir and ISS using elements from the last few days of 1999
    and did the predictions for January of 2000 (it was still 1999 when I did
    I was curious what would happen after the element dates rolled over. 
    I ran it today, asked for the predictions - the program assumed this was
    January,1980. Needless to say, it didn't work. I decided try something. I
    changed the first numeral of the date from a 0 to an 8, thereby making the
    date 1980. Ran it again and the results matched up very well with the ones
    I ran with the '99 elements. Some were off by 1 degree in altitude
    (differences in postion of moon?), but good enough for me. The times
    matched up as did the azimuth,the direction, and most of the altitudes. I'm
    Friday I'll be able to see if the results I got were accurate.
