    Observed what obiously was near-zenith pass of Lacrosse 5 from
    Moscow close to this elset.
    
    At 19:31:24 crossed the line of Kappa and Iota UMa, to the
      north of Iota, at the distance equal to Kappa-Iota distance.
    At 19:32:10 passed between Beta and Alpha UMa (dividing the
      line at 4 to 6 ratio).
