	abstract = {Time series analysis of 6 nights of CCD observations of WZ Sge after it{\textquoteright}s unexpected superoutburst on July 23, 2001 has shown highly asymmetric periodic variations with a period 0.0566513(22)deg, full amplitude 0.218(4)m and a very high asymmetry M-m=0.670(9), a secondary minimum 0.38P after the main one. The initial epochs are T<SUB>max</SUB>=BJD 2452118.7483(3) and T<SUB>min</SUB>=BJD 52118.7670(2). The characteristics of the phase light curve are listed. In addition, we have found superhumps with a semi-amplitude of 0.021(2)m and an ephemeris T<SUB>max,sh</SUB>=BJD 2452117.6830(8)+0.057435(45)d E. Other peaks at 21 and 25 minutes possibly correspond to quasi-periodic oscillations with an effective semi-amplitude of 0.014m.},
