  We calculate the quarkonium dissociation rate in the P and CP-odd domains
(bubbles) that were possibly created in heavy-ion collisions. In the presence
of the magnetic field produced by the valence quarks of colliding ions,
parity-odd domains generate electric field. Quarkonium dissociation is the
result of quantum tunneling of quark or antiquark through the potential barrier
in this electric field. The strength of the electric field in the quarkonium
comoving frame depends on the quarkonium velocity with respect to the
background magnetic field. We investigate momentum, electric field strength and
azimuthal dependence of the dissociation rate. Azimuthal distribution of
quarkonia surviving in the electromagnetic field is strongly anisotropic; the
form of anisotropy depends on the relation between the electric and magnetic
fields and quarkonium momentum. These features can be used to explore the
properties of the electromagnetic field created in heavy ion collisions.
