Abstract

Pulse arrival-time measurements made during the period 1987-1994 at the Mt Pleasant Observatory have revealed the first observed glitch in PSR B1727-47 and a continuation of the known high glitch rate in PSR B1737-30. The observations also show an unusual sequence of alternating microjumps in the rotation rate of PSR B1240-64 and the possibility of free precession in PSR B0959-54. The observations and results are discussed in terms of current neutron star theories. © 1997 RAS.
