Abstract

The results of the CCD observations of the 2002 superoutburst of V1141 Aql are described. We have detected clear superhumps characterized by the period of 0.05930(5) days. There was another, much weaker, modulation in the light curve of V1141 Aql. Its amplitude is equal to 0.012±0.002 mag and its period to 0.03923(8) days. We have also discovered quasi periodic oscillations (QPOs) with a mean period equal to 130 s and amplitude of 0.025±0.004 mag.
