November 15, 2012: As announced in [baavss-alert] on 15 November 2012, Dr. Chris Lloyd (University of Sussex) has requested that the SU UMa-type dwarf nova V452 Cas continue to be observed in order to maintain the good historical coverage of its superoutbursts. He writes: "Over the past several years we have accumulated enviable coverage of V452 Cas' superoutbursts but the general monitoring has dropped off recently as people have moved on to more interesting objects.
