  We present low-state IUE spectroscopy of the ROSAT-discovered polar
RXJ1313.2-3259. The SWP spectrum displays a broad Lyman alpha absorption
profile, which can be fitted with a two-temperature model of a white dwarf of
Twd=15000K with a hot spot of Tspot=34000K which covers f~0.01 of the white
dwarf surface. The white dwarf temperature is atypically low for the long
orbital period (4.18h) of RXJ1313.2-3259. This low temperature implies either
that the system is a young CV in the process of switching on mass transfer or
that it is an older CV found in a prolonged state of low accretion rate, much
below that predicted by standard evolution theory. In the first case, we can
put a lower limit on the life time as pre-CV of 10e8yrs. In the second case,
the good agreement of the white dwarf temperature with that expected from
compressional heating suggests that the system has experienced the current low
accretion rate for an extended period >10e4yrs. A possible explanation for the
low accretion rate is that RXJ1313.2-3259 is a hibernating post nova and
observational tests are suggested.
