    My 1st observation on this satellite was at about 19:55 UT with 25 degrees
    elevation. Magnitude estimate was difficult as a street lamp was close to
    it.
    I think (may be pessimistic) it was +6.3.
    Two minutes later a +6.0 magnitude object followed a similar track.
    Likely the 02009B object. The TLE's confirm object B is behind object A.
    
    I also expect Envisat to be much brighter with "better" orientation w.r.t.
    observer and sun and expect even negative magnitudes on very favourable
    transits. I can compare this with Terra (99068A), which once had -4.
