Is irxs j012750.5+380830 a superhumping intermediate polar?

The first time-series observations of the poorly observed X-ray transient 1RXS J012750.5+380830 are reported from the 2020 October outburst. The outburst was short, 3-4 days, and had an amplitude of 4(m).7.The system shows extreme flickering consistent with a magnetic CV, and on one night periodic variations were also found at P-wd = 454.2 + 0.5 s or f = 190.2 + 0.2 c/d, and this could be interpreted as the white-dwarf-spin period. Periodic variations were also found near the orbital period, which could be interpreted as superhumps or orbital modulation.
