The 2011 February superoutburst of the dwarf nova SDSS JII2003.40+663632.4

We report unfiltered photometry of SDSS JII2003.40+663632.4 during the 2011 February outburst, which revealed the presence of superhumps with peak-to-peak amplitude of up to 0.22 magnitudes, showing this to be an SU UMa type dwarf nova. The outburst amplitude was 5.4 mags above mean quiescence and i...

Zusammenfassung:We report unfiltered photometry of SDSS JII2003.40+663632.4 during the 2011 February outburst, which revealed the presence of superhumps with peak-to-peak amplitude of up to 0.22 magnitudes, showing this to be an SU UMa type dwarf nova. The outburst amplitude was 5.4 mags above mean quiescence and it lasted at least I2 days. The mean superhump period during the plateau phase was [P.sub.sh] = 0.07057(19)d.
