Abstract
We present the optical light curve of EG Cancri during its outburst in 1996–1997. It displayed some brightness fluctuations in the phase of decline. Mini-outbursts were detected. Optical spectra obtained during the decline showed it to be a dwarf nova on account of its broad absorption lines superimposed on a blue continuum. Optical spectra near minimum brightness revealed doubled Balmer lines in emission, over broad absorptions, but no HeII4686. An additional heating presented in the last stage of decline. CCD time-resolved photometry showed a possible orbital period 0.0575(26) day. Superhumps was observed during outburst byMatsumoto(1996). EG Cancri is a short-period CV which has a large-amplitude outburst(∼ 7 mag), a slow decline from outburst, and a long interval between outburst. From the above properties, a classification as a WZ Sge type DN is plausible.
