We present the first optical photometry of the counterpart to the candidate intermediate polar RX J0153.3+7446 .
This reveals an optical pulse period of 2333 \pm 5 s. Reanalysis of the previously published ROSAT X-ray data reveals that the true X-ray pulse period is probably 1974 \pm 30 s , rather than the 1414 s previously reported .
Given that the previously noted orbital period of the system is 3.94 h , we are able to identify the X-ray pulse period with the white dwarf spin period and the optical pulse period with the rotation period of the white dwarf in the binary reference frame , as commonly seen in other intermediate polars .
We thus confirm that RX J0153.3+7446 is indeed a typical intermediate polar .
