In 1985 a outburst of the symbiotic star AS 296 with amplitude ..delta..U greater than or equal to 1/sup m/4 was observed. During the outburst, the light of the cold component of this star did not change significantly. Lines of H I, He I, He II, Fe II, N III, and C III were observed in the spectrum of AS 296 but without significant emission in the forbidden lines. The temperature of the hot component during the outburst was approx. 8.6 x 10/sup 40/K, and its bolometric luminosity was about equal to that of the cold star. Observations of AS 338 in 1985 showed that the outburst of this star discovered in 1983-1984 continues. A spectrum of AS 360 obtained in September 1982 indicates that an outburst of this star occurred during the time of observations.
