PV Per has faded quite rapidly as the following observations indicates.
mid-UT V-C S.D. N band V-mag
--------------------------------- -----
951013.771 2.870 0.054 2 V 17.0
951014.631 4.756 0.000 1 V 18.9:
comparison star: 02h42m54s.77 +38o04'08".5 (J2000.0)
GSC V=14.2 (14.15 in revised VSNET chart)
The rate of decline also suggests that this dwarf nova is a ultrashort
orbital period system. From this point of view, Sep. 15 outburst
detected by T. Vanmunster might be a superoutburst.
Further close monitoring would be recommended. One should again
remember that the present short outburst may trigger a superoutburst.
Please continue a close watch.
