The detection of glitches or timing noise in the rotation of central compactobjects (CCOs) in SNRs is unprecedented for pulsars with such small spin-downrates. It maysupport a timely conjecture that glitches could be triggered in CCOs bydiffusion of a strong buried internal magnetic field that rivals in strengththose found in magnetars NSs with surface magnetic fields 10000 times greaterthan the dipole fields inferred for CCOs. This proposal is to continue timingPSR J0821-4300 the CCO in Puppis~A to distinguish glitches from timing noise orpossible low-level accretion and to monitor its spin-down rate to test for achange in surface magnetic field strength to compare to theoretical models [truncated!
