    Thank you Phillip Clark for alerting us that the U.S.A. no longer publishes
    2-line elements of Japan's two IMINT satellites, IGS 1A and IGS 1B.
    
    As an aid to observers, I have appended their five most recent elsets, taken
    from my archive. 
    
    The standard magnitudes have been derived from Russell's four IGS 1A
    observations and his seven IGS 1B observations, through 2003 Apr 10 UTC.
    
    Note that IGS 1A recently manoeuvred to raise its orbit and increase its
    inclination. There is also an indication of a small recent manoeuvre by IGS
    1B.
    
    I believe that I have a nearly complete archive of both objects' elements
    through early on day 094. If anyone has elements that fill in the gaps after
    that point (refer to the appended sets), I would appreciate receiving them. To
    avoid cluttering SeeSat-L, please send them to me. I will compile them and
    make them available to all who request them.
