Further close monitoring would be recommended. One should again remember that the present short outburst may trigger a superoutburst. Please continue a close watch. Following outbursts were observed from Sonneberg plate collection. My comments are added based on recent classification of these stars as probable SU UMa-type dwarf novae.
Normal outbursts seem to be rare.
Some may be missed due to their faintness, though. Rather numerous outbursts were recorded. Only the dates of maxima are cited here.
