  We study the thermodynamics of the Bose-condensed atomic hydrogen confined in
the Ioffe-Pritchard potential. Such a trapping potential, that models the
magnetic trap used in recent experiments with hydrogen, is anharmonic and
strongly anisotropic. We calculate the ground-state properties, the condensed
and non-condensed fraction and the Bose-Einstein transition temperature. The
thermodynamics of the system is strongly affected by the anharmonicity of this
external trap. Finally, we consider the possibility to detect Josephson-like
currents by creating a double-well barrier with a laser beam.
