The Strömvil seven-color photometric system, a combination of the four filters of the Strömgren system and three filters of the Vilnius system, is described. The system is able to determine the temperature, gravity and interstellar reddening of stars from photometric measures alone. The main observational programs underway during the decade are: (1) Setting up the primary Strömvil standards; (2) precise photometry of the open cluster M 67 and several globular clusters at the VATT telescope, Arizona; (3) photometry of southern globular clusters at CASLEO, Argentina, On the data reduction side the CommandLog code has been written which automates the process of data reduction. In August–September of 2006 a workshop on the Strömvil system was held at the Moletai Observatory, Lithuania. Some papers presented in the workshop are being published in this issue of Baltic Astronomy.
