  We have detected sporadic, bright, short-duration radio pulses from PSR
J0901$-$4624. These pulses are emitted simultaneously with persistent, periodic
emission that dominates the flux density when averaging over many periods of
the pulsar. The bright pulses have energies that are consistent with a
power-law distribution. The integrated profile of PSR J0901$-$4624 is highly
polarized and shows four distinct components. The bright pulses appear to
originate near the magnetic pole of the pulsar and have polarization properties
unlike that of the underlying emission at the same pulse phase. We conclude
that the bright pulses represent a secondary giant-micropulse emission process,
possibly from a different region in the pulsar magnetosphere.
