We have found one more literature on PU Per and PV Per (Busch, H.,
H\"aussler, K., 1979, VSS 9, 125). 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.

2439051.34 [16.0
9052.36 15.5 superoutburst
9053.44 16.0
9056.48 16.0
9380.56 16.0
9385.52 14.7 superoutburst lasting at least 10 days
9386.53 14.7
9388.49 15.0
9390.61 15.5
2441300.23
- .49 15.6-15.7 (five plates) = identical with the second outburst
1304.38 [16.0 by Romano, Minello (1976)
= superoutburst
From these data, one may conclude:
1) The shortest recorded interval between superoutbursts is ~330 day.
2) Normal outbursts seem to be rare. Some may be missed due to their
faintness, though.
PV Per

Rather numerous outbursts were recorded. Only the dates of maxima
are cited here.
