    As part of my ongoing research into the orbit of Sputnik 1 and (primarily) its rocket body, I sought insight from the
    initial orbital elements of Sputnik 2 (1957 Beta, 57002A / 00003). I am sufficiently confident of my results of the
    latter to post them.
    
    Sputnik 2                                               214 X 1625 km
    1 00003U 57002A   57313.64486383  .00328310  00000-0  15429-2 0    01
    2 00003  65.3223  98.6145 0967080  57.4825 311.5983 13.92241025    09
    Arc 19571104.82-1109.71 WRMS resid 0.336 totl 0.051 xtrk
    
    Since the elements are reasonably accurate, and are derived from observations over the five days immediately following
    the launch (1957 Nov 03, 02:30:42 UTC), they can be propagated to provide an accurate estimate of the orbit at the first
    ascending node:
    
                                                            214 X 1655 km
    1 00003U 57002A   57307.17013519  .00324593  00000-0  15429-2 0    08
    2 00003  65.3223 115.6609 0985485  60.1454 309.3870 13.87989580    01
    
    The inclination ad RAAN are accurate to within about 0.01 deg; argument of perigee to within ~0.1 deg.
    
    Relative the geoid, the orbit was 222 x 1676 km, accurate to 1 to 2 km.
    
    I have appended the observations retained in the above solution, including site coordinates. The data consists of visual
    and theodolite observations from Moonwatch and professional observers. Epoch was not reported, so I used 1950.0 as the
    default, and occasionally other values that seemed to make sense.
