We report here VLBI observations at four epochs of the source BL Lacertae made with the U.S. VLBI Network (plus Bonn) at 10.65 GHz which show clear evidence of uniform superluminal expansion at v/c = 4.4 ± 0.2 (H0 = 55 km s−1 mpc−1). The maps, which were made every three months from 1981.76 to 1982.75 (Figures 1, 2), were part of an ongoing program of VLBI observations of BL Lacertae at 5 and 10.65 GHz starting in 1980.4, near the beginning of a series of violent flux outbursts (Aller, Hodge, and Aller, 1983; Aller and Aller, 1984). Previous results from earlier epochs have been reported by Mutel, Aller, and Phillips (1981) and Phillips and Mutel (1982).
