We report CCD photometry and spectroscopy during 2006 outburst of the dwarfnova SDSS J102146.44+234926.3 (SDSS J1021). The photographic plates from theMAO, SAI and CrAO plate archives, which cover the position of the SDSS J1021,were inspected for the presence of previous outbursts. We also present theBVRcIc photometric calibration of 52 stars in SDSS J1021 vicinity, which haveV-magnitude in the range of 11.21-17.23m and can serve as comparison stars. Thelarge amplitude of the SDSS J1021 outburst of 7m, superhumps with a periodbelow the ''period gap'', rebrightening during the declining stage ofsuperoutburst, rarity of outbursts and obtained spectrum allow to classify thisobject as a WZ Sge type dwarf nova.
