This pulsar has at least two emission states. Usually, it is thought to have three states: strong, weak and "off", but Young et al. (2014) suggested that the "off" state may actually be the bottom end of the pulse-intensity distribution of the weak state. They also showed that the pulsar remains in the strong state for ~200-6000 pulses with apparent nulls of up to a few pulses at a time.
