Determination of the superhump period of the dwarf nova V701 Tau during the 2005 December superoutburst

Abstract

We report new measurements of the superhump period of the UGSU-type dwarf nova V701 Tau during the 2005 December superoutburst. Using unfiltered time series CCD observations on 3 nights, we determine a probable superhump period Psh = 0.0690, plus or minus 0.0002d, but note that our data also permit a possible shorter period of 0.0663, plus or minus 0.0002d. The longer period agrees with the value measured during the first recorded superoutburst in 1995.
