We report the detection of a large glitch in the pulsar B0919+06 (J0922+0638). The glitch occurred in 2009 November 5 (MJD 55140) and was characterized by a fractional increase in the rotation frequency of Δν/ν ~ 1.3 × 10–6. A large glitch happens in the pulsar whose rotation has an unstable character. We present the results of the analysis of the rotation behavior of this pulsar over the 30 year time span from 1979 to 2009. These results show that the pulsar's rotation frequency underwent… Expand

Multifrequency behaviour of the anomalous events of PSR J0922+0638
PSR J0922+0638 (B0919+06) shows unexplained anomalous variations in the on-pulse phase, where the pulse appears to episodically move to an earlier longitude for a few tens of rotations beforeExpand
Pulsar state switching, timing noise and free precession
Recent radio pulsar observations have shown that a number of pulsars display interesting longterm periodicities in their spin-down rates. At least some of these pulsars also undergo sharp changes inExpand
