   As Maehara-san has reported, the current outburst of SDSS
J225831.18-094931.7 is a superoutburst.  Based on the data by
Maehara-san, Nakajima-san and Seikei Astronomy and Meteorology Club,
the best superhump period is 0.08618(4) d (a longer alias may not be
completely excluded).  The object is confirmed to be a long-Psh
SU UMa-type dwarf nova.  Since the object is bright enough (mag about
12.6 mag) further observations are encouraged.
