We present new results from our ROSAT HRI observations of soft high-galactic latitude ROSAT all-sky survey sources. A 42 ksec pointing on UU Col reveals that the two independent coherent periodicities known from our optical photometry are also present in the soft X-ray flux confirming the soft X-ray intermediate polar nature of this system. In a 13.4 ksec pointing on RX J0806.3+1527 a (321.5393+/-0.0004) s pulsation with a modulation amplitude of ~100% is detected as the only consistent signal in the 0.0002-0.0052 Hz frequency range. Based on its X-ray and optical properties, we suggest that RX J0806.3+1527 is another member of the new class of soft X-ray intermediate polars. Alternatively, it could be a double-degenerate polar. .
