  We report unfiltered CCD observations of the first confirmed superoutburst of
the SU UMa-type dwarf nova SS LMi in October 2006. From a quiescent magnitude
of around 21.7 it rose to 16.2, an outburst amplitude of about 5.5 magnitudes.
It declined at 0.17 mag/d for 5 days before slowing to 0.11 mag/d for a further
3 days. The light curve revealed common superhumps with a peak-to-peak
amplitude of 0.3 magnitude, which decayed and then re-grew concurrently with
the change in decline rate. These were followed by a phase-changing transition
to late superhumps. Analysis of these observations has revealed evidence for an
orbital period of 0.05572(19) d and a common superhump period of 0.05664(2) d,
giving a fractional superhump period excess of 0.017(5). From astrometry of SS
LMi in outburst we have established for the first time its correct position as
RA 10h 34m 05.85(1)s, Dec +31deg 08m 00.00(18)s (J2000). The position commonly
given for SS LMi is that of a nearby star.
