ABSTRACT

We present new results of a preliminary analysis of a large set of Strömgren measurements collected between the years 2006 and 2011 with the aim of discovering the true nature of the V994 Herculis. Thanks to the high precision of these observations, we have detected a few new tinier light minima between 0.01 - 0.04 mag deep in the v-filter with a 3.92 d orbital period. We think these eclipses show that V994 Her would consist of a more complex hierarchicalmultiple star system of at least six components.
