We have recently detected a glitch in the spin of 1E 1207.4-5209 comma the compact central object openParCCOclosePar in SNR PKS1209-51-52 comma and possibly from a second CCO that we are monitoring comma PSR J0821-4300 in SNR Puppis A. This is entirely unexpected for pulsars with a spin-down rates as small as those found for CCOs. These detections supports a recent conjecture that glitches could be triggered by the diffusion of a buried magnetar strength internal field comma 10 comma 000 larger than the dipole fields inferred for CCOs. Here comma we propose to search for similar timing anomalies from the third known CCO pulsar comma PSR J1852+0040 in SNR Kes 79. A detection will reveal a general property of CCOs with important theoretical implications for NS B-field structure and emission mechanisms comma andevolution.
