[vsnet-outburst 1193] WY Tri - a new UGSU type variable
Dear colleagues,
I just concluded a CCD photometry session on WY Tri, lasting for 4.6 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 0.38 mag
modulation, to be attributed to superhumps. A first rough estimate of the
superhump period yields a value of 0.0786 d.
The above observations thus establish WY Tri as a new member of the UGSU
type of cataclysmic variables !
Further high-speed photometry is highly recommended, to settle the precise
superhump period value. Support from other observatories would be highly
appreciated, although I assume that most attention likely will go to the RZ
Leo outburst ...
Best regards,
Tonny Vanmunster
