Superhumps in V1141 Aquilae

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 $0.012\pm0.002$ 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 $0.025\pm0.004$ mag.
