    I believe it is similar in design and mission to the EORSATs
    with MM=15.52, that have been operating in pairs or triplets for
    many years (1-2 years/satellite). Instead of being deorbited at the
    end of the useful lifetime, it ended up in a higher orbit.
    
    They were described as '6.0 0.0 0.0' ,i.e. spheres, in TLEs, and I 
    have seen a fair number of passes, always at +1 - +2 at short range. 
    However, images indicate a cylindrical shape. 1996-069A 24670 
    COSMOS 2335 Launched 12/11/1996 was lowered, and decayed 01/01/1999;
    1997-079A 25088 COSMOS 2347 exploded in orbit 12/12/1999; see
    http://www.algonet.se/~b_gimle/eorsat.htm and
    http://www2.satellite.eu.org/seesat/Dec-2000/0378.html
    
    According to Phillip Clark COSMOS 2347 was the final of the series.

    , but Cosmos 2367 has the same kind of orbit with a groundtrack
    repeat in three days -55 minutes.
