I made unfiltered CCD observations (differential photometry) of RY Ser on 
August 14/15, during about 1.97h, using the 0.25-m f/6.3 telescope and 
ST-7 CCD camera at my observatory. The resulting light curve does not show
any apparent periodic signal related to superhumps.

I did not attempt astrometry, but if you're interested, I'm willing to 
forward you one of my RY Ser FITS files with pleasure, so that you can
perform astrometric reductions on this interesting object.

Kind regards,
