We discuss the discovery of ‘notch‐like’ features in the mean pulse profile of the nearby, bright pulsar B0950+08. We compare these low‐level features with those previously seen in the pulse profiles of pulsars J0437−4715 and B1929+10. While J0437−4715 is a binary millisecond pulsar and B0950+08 and B1929+10 are isolated, slow pulsars, all three pulsars are nearby and very bright. Furthermore, all three have detectable emission over an unusually wide range of pulse phase. We describe the similar properties of the notch features seen in all three pulsars and discuss possible interpretations.
