  We present neutron diffraction measurements in high magnetic fields (0 to
14.5 T) and at low temperatures (2.5, 2.3, 0.77 and 0.068 K) on single crystals
of the tetragonal heavy fermion antiferromagnet Ce2RhIn8. For B//[110] the
field dependence of selected magnetic and nuclear reflections reveals that the
material undergoes several transitions, the temperature dependence of which
suggests a complex B-T phase diagram. We present the detailed evolution of the
integrated intensities of selected reflections and discuss the associated
field-induced transitions.
