Abstract (from CDS):

In this paper we report photometric observations of AL Com, V544 Her, V660 Her, V516 Cyg and DX And taken during the descending phase after an outburst. For four of these variables we calibrated comparison stars in the field of view. Our observations cover the period in which AL Com showed the larger optical outburst since 1974, and V660 Her showed the larger outburst ever reported in the literature (B≃14.3). The optical spectral distribution of DX And, AL Com and V660 Her shows that the model of the steady-state accretion disk does not provide a good representation of the optical continuum during the decline phase of a dwarf nova outburst.
