V803 Cen: further observations from Berto Monard Dear Colleagues, We have received further data (two nights) from Berto Monard. The early stage of the V803 Cen superoutburst has been exquisitely recorded! The superoutburst plateau phase lasted at least until the June 8.0 UT. The object entered the rapid fading stage probably at around June 8.5. The object faded by 1 mag within the next 10 hours! Althought the fading become slightly slower, the linear fading trend continued at least until June 9.0 UT. Superhumps were singly peaked during the early plateau phase, but secondary maxima appeared during the rapid fading stage (comprising our "familiar" profile in helium SU UMa-type star). This behavior resembles "late superhumps" in hydrogen-rich SU UMa-type stars, although there is a slight difference of relative amplitudes of main and secondary superhump maxima between V803 Cen and hydrogen-rich SU UMa stars. The present epoch corresponds to the earliest stage of a superoutburst, and the object is expected to rebrighten to a longer-lasting superoutburst plateau stage. Please keep observing!
