AO Oct: A large amplitude outbust in 2000 September

The large-amplitude dwarf nova AO Oct started its rare outburst as reported by R. Stubbings on September 2 (14.4mag). T. Kato commented the large amplitude (the object is reported to be mag 21 at minimum) suggests an SU UMa-type dwarf nova (vsnet-campaign 468). T. Kato wrote in [vsnet-campaign 477] that the observed subsequent fade of 0.8 mag in three days may look rapid for typical superoutbursts of SU UMa stars, which may suggest that AO Oct is an SS Cyg type dwarf nova, or may belong to large-amplitude rapid faders among SU UMa-type systems, like V592 Her.
