The results of electrophotometric observations of 51 stars in multiple systems of the Trapezium type in the Strömgren-Crawford six-color photometric system are given. The following Trapezia were selected from the Abastumani Catalog for observations: ABAO 2, 8, 34, 48, 51, 62, 94, 313, 316, 348, 356, 359, 363, 387, 396. The observations were made on the 125-cm, automatically computer controlled, reflecting telescope of Abastumani Astrophysical Observatory. The results of the observations are given in Table 1. Most of the components of the observed Trapezia belong to the early “B ” group based on Stromgren ’s criteria. The absolute stellar magnitudes of the Trapezia components are determined and their distance moduli are calculated (Table 2). It is concluded that these Trapezia are physical systems with a high probability.
