OT J075418.7+381225: superhump evolution

   We have received a series of data from Enrique de Miguel
and William Stein.  The stage A and B period evolution
was very well recorded.  The mean period for stage B was
0.07194(4) d with a large Pdot = +20(2)*10^(-5).
The outburst was apparently a precursor-main superoutburst
type and the period evolution did not resemble that of
a WZ Sge-type dwarf nova despite the large outburst amplitude.
