    Hi list,
    
    Nadezhda 6 (26384/00033A) gave a wonderful surprise performance this
    morning (Thursday, 4:14MEST = 2:14UTC) when it passed together with its
    tumbling SL-08 booster (26387/00033D) through Perseus, a mere 2 or 3 degree
    apart. At first glance it looked like a severely damaged NOSS-triangle. :)
    There obviously were no really fresh elsets at hand for these objects, so I
    checked with these somewhat dated elements:
    
    Nadezhda 6
    1 26384U 00033A   00229.86982120 +.00002190 +00000-0 +47138-3 0 00380
    2 26384 098.1286 182.6081 0016831 207.7853 152.2461 14.59385901007201
    Nadezhda 6 r
    1 26387U 00033D   00235.90469505 +.00001143 +00000-0 +24087-3 0 00365
    2 26387 098.1344 188.7026 0025576 198.9645 161.0601 14.61155508008106
    
    ...which put Nadezhda 6 slightly in the lead, but in fact it was notably
    behind its upper stage.
    
    1.) The orbits of these two don't look particularly similar to me. Are such
    twin passes common for these objects? If not, I can only suggest to take
    the opportunity and watch them. Quite a sight.
    
    2.) Is 26387/00033D a known tumbler? I couldn't time it, but to my amateur
    eyes it looked somewhat irregular, probably tumbling on more than one axis.
    Anyone having this one already on his list?
    
    
    CU!	Markus (51.7251N, 8.7429E, 113m)
