CG Dra fading, right after outburst. Good quality data. The eclipse profile is back to V-shape with gentle egress. Mild bright spot hump – I assume the accretion disk is still contributing to the overall brightness immediately after the outburst. Initially I thought that the eclipse profile change may be correlated with outbursts, as EX Dra, for example, shows V-shaped eclipses on the rise and during its outburst stages, but its eclipses become U-shaped on the decline and during the quiescence. But this is not the case with CG Dra, as we have seen very prominent V-shaped eclipse with pronounced bright spot orbital hump on May 28th. My quiescence eclipse profile folder contains a wide variety of V and U shapes.
