At Woodchester Observatory (located near Adelaide, Australia) we carry out observations of the Vela pulsar (J0835-4510) with a dedicated 2.3 meter dish. Approximately 1 hour transit observations are performed daily. Dual polarization measurements are made at a central frequency of 820 MHz and have a bandwidth of 8 MHz.
We confirm the detection of the glitch in PSR J0835-4510 reported by Zubieta et al. (ATel #16608). The first post-glitch observation was taken at MJD 60430.366 (2024-04-30 UTC), and was confirmed the next day at MJD 60431.363. Our preliminary analysis shows a change in its rotation frequency by delta_F0/F0 = 2.9E-6, consistent with ATel #16608. The pulsar timing showed no glitch in the observation on 2024-04-29 UTC, at MJD 60429.369.
We will continue to observe the pulsar daily and encourage other observers to monitor the glitch recovery phase.
