Dear colleagues,
I just concluded a CCD photometry session on RZ Leo, lasting for 4.1 hours,
using the 0.35-m f/6.3 telescope at CBA Belgium Observatory [2000, December
20/21]. All FITS images were acquired with an ST-7 CCD camera without
filters, and were instanteneously processed and reduced (PSF photometry).
The resulting real-time light curve clearly shows the presence of a 0.20 mag
modulation, to be attributed to superhumps. A first rough estimate of the
superhump period yields a value of 0.079 d.
The above observations thus establish RZ Leo as yet another new member of
the UGSU type of cataclysmic variables !
Further high-speed photometry is highly recommended during the present
outburst of this interesting object !!
Best regards,
