DV Sco superoutburst
Berto Monard has kindly provided time-series photometry on Sep. 3.
The data clearly show superhumps, indicating that the current outburst
is a superoutburst. The superhump period is around 0.106 d,
suggesting that the previous determination (vsnet-alert 8325) referred
to an one-day alias. The conclusion "DV Sco is one of the rare
dwarf novae in the period gap" is unchanged, or even more strongly
supported. Further time-resolved photometry is encouraged.
