Abstract
Eight years of timing observations of PSR 1641 – 45 are presented. During this time, two sudden increases in rotation rate were observed. One of these glitches is of similar size to those observed regularly in the Vela pulsar, and is the second such event observed in PSR 1641 – 45. Some features of this glitch are not easily explained within the context of the vortex creep model of glitches. Timing noise similar to that seen in other pulsars is evident, particularly after the glitch.Keywords
