    Your second observation looks like it may be a match, running about 45 min
    early. To produce a search elset, I have changed the rate of decay of the latest
    90040 elset derived from observations, to closely agree with your observation:
    
    1 70000U          08060.14853200  .00001374  00000-0  23100-2 0    00
    2 70000  27.4308 143.7982 6978822  90.2575 342.8454  2.59369622    01
