    Kevin Fetter spotted Elisa E24 as an UNID. Using estimated orbital elements derived from his observations, Scott Tilley
    acquired a pair of objects. I have assigned IDs to their observations, as follows:
    
    38008 11 076B   1775 G 20120711030156431 15 25 1836711+044062 37 S
    38008 11 076B   1775 G 20120711030211646 15 25 1835681+110650 37 S
    38008 11 076B   1775 G 20120711030223258 15 25 1834490+162168 37 S
    38008 11 076B   1775 G 20120711030237305 15 25 1833356+233268 37 S
    38008 11 076B   8049 G 20120711062112966 15 25 1653692+390197 37 S
    38010 11 076D   8049 G 20120711062112966 15 25 1651880+385926 37 S
    
    Here are approximate elements:
    
    Elisa E24
    1 38008U 11076B   12193.25543597  .00000257  00000-0  50000-4 0    06
    2 38008  98.2362 269.5836 0007500 178.1152 182.0079 14.63106572    09
    
    Elisa E12
    1 38010U 11076D   12193.25543597  .00000257  00000-0  50000-4 0    09
    2 38010  98.2362 269.6367 0007500 178.1152 182.0079 14.63106572    02
    
    I differentiated between the objects based on RAAN, since E12 had been ~0.05 deg east of E24, but that may no longer
    apply.
    
    W11 (11076A / 38007) and W23 (11076C / 38009) may be ~0.6 deg west of E12 and E24, perhaps trailing by 1100 s. A planar
    search of the following elements may turn them up:
    
    1 70000U          12193.26820000  .00000257  00000-0  50000-4 0    07
    2 70000  98.2362 269.0000 0007500 178.1152 182.0079 14.63106572    05
