Descripción
We have identified IGR J17303-0601 (1RXS J173021.5-055933) as an
intermediate polar (IP). The optical counterpart is USNOA2.0
0825_10606993 (RA=17h30m21.9s Dec=-05d59m31s). Using optical photometry
obtained in 2003 at the JKT and at the OGS we determine the white dwarf
spin period to be 120s, which is the second-shortest spin period
discovered so far (after AE Aqr, Pspin=33s). The spin folded light
curve has a double-pulse structure, suggesting that both accreting
poles / accretion curtains contribute to the optical light.
