Nova Cas 1993 (=V705 Cas) was discovered ten days before it reached its maximum brightness in the V colour (Vmax = 5.53 mag and Bmax = 6.14 mag) on 1993 December 17.29 (Munari et al. 1994b). The pre-nova varied around 18… 18.5 mag and 17… 17.5 mag in B and V, respectively. No more prominent light fluctuations were found (Munari et al. 1994a). The nova started to fade rapidly, entering the deep minimum typical for the transition period of the DQ Her-subclass of novae in 1994 mid-February. The time development of the UV luminosity of the nova was discussed by Hauschildt et al. (1994). In this paper, we analyze our original UBV photometric data and all the available data obtained by the other authors. We derive the basic parameters of the nova and present the results of our search for short-term periodicities.
