  The orbital period of the eclipsing cataclysmic variable SDSS
J170213.26+322954.1 has been measured as 0.10008215+/-0.00000001d using
observations of eclipses during the first recorded superoutburst in October
2005 together with eclipses observed in quiescence in July 2003. This period
puts the system in the centre of the period gap. Observation of superhumps
during the October 2005 outburst with a period of 0.10496+/-0.00015d confirms
this to be a UGSU-type system with a period excess of 4.9%.
