5905 Johnson: A Hungaria Binary

The Hungaria asteroid, 5905 Johnson, was previously confirmed to be a binary system. Follow up observations were obtained by the authors during a 2008 campaign in order to further define the system. The data from this second campaign found the rotation of the primary P1 = 3.7826 ± 0.0002 h. The orbital period was Porb = 21.78 ± 0.01 h.
