PV Per [UGSU, 14.9p - 20:p]
===========================
Photometry of PV Per on 1996, September 15/16 at the Center for
Backyard Astrophysics Belgium (using a 25-cm SCT with unfiltered
ST-7 CCD) clearly reveals the existence of superhumps with a semi-
amplitude of 0.18 mag.
Determination of the superhump period is rather difficult due to
the short observing window and the presence of low clouds. The most
probable period is 112 min (PDM), a value that will need further
refinement. Follow-up observations at different longitudes are
highly encouraged. We plan another photometry session on PV Per
tonight.
Our set of observations finally revealed the SU UMa type nature
of this dwarf nova !
The present outburst of PV Per (a CVAP object) was detected by
Eric Broens, Mol, Belgium [CVC 108]. Thanks Eric, for the
early notification !
