Using the 35 speckle measurements performed with PISCO in Merate between 2004 and 2006, and some complementary new astrometric measures, we present a new orbit for the visual binary ADS 8630 = γ Vir. This new series of measurements was essential for constraining the 169 year-period orbit since it covers an arc of 130° in the apparent orbit and includes the periastron passage of 2005.
