    From station 5919 I observed USA 129 and USA 116, and while waiting for
    the latter accidentally Lacrosse 4 as an UnId (no points taken) and a two
    oldies (Transit 4A  61-15A 00116 and Alouette 1 62-49A 00424)
    
    My cassette memo was positioned near the end of tape - not beginning as I
    saw it - so I got only a few good points. Luckily, I remembered two of
    the USA 116 fixes, and the first point was within 1/20 or 1/30 from one
    of a split. Most of the other splits were also within +- 1/10 of the
    pairs, and I could definitely identify the pairs.
    
    I found no other candidate to match the USA 116 obs, and increasing just
    B* and ndot2 of the 02365 elset (4.5 minutes early) I get a very good
    match in both time and position with SGP and SGP4 (in SkyMap)
