Dear,
Observations of DV UMa on Dec 10/11, 1999 at CBA Belgium Observatory, using a 0.35-m f/6.3 telescope with unfiltered SBIG ST-7 CCD, show the existence of deep eclipses (about 1.5 mag) and prominent superhumps (about 0.5 mag). When I compare this set of observations with the ones I obtained during the April 1997 outburst of DV UMa, the most striking difference clearly is in the shape and depth of the eclipses, the present ones being much deeper and 'sharper'.
Kind regards,
Tonny Vanmunster
