During the follow up timing observations, the pulsar could not be detected for 280 days. Since it started being detected again, the ON and OFF emission states have not been quasi-periodic as reported for PSR B1931+24. We see that the spin-down rate is different for each ON phase with a different profile each time, in stark contrast to observations in other intermittent pulsars. We also report on the detection of continuum, unpulsed radio emission seen in the images made during the OFF states. |
