Abstract The results of spectral and photometric studies of Herbig Be-type star AS 310 have been presented. Photometric observations in the BVRcIc bands performed in 2016–2021 showed that the amplitude of the seasonal brightness variations of the star changes smoothly in different years and reaches a maximum of approximately around Δ V 0.6 mag in 2018. The star is more often in a weak state of radiation, but from time to time an increase in its brightness is observed. With a decrease in brightness in the V-band, the star’s radiation in the blue color increases, while in the red part of the spectrum, it decreases. Searches for periodicity in the light variations did not reveal definite periods of variability. The emission components observed in the hydrogen and forbidden nitrogen lines are rather formed in the nebula where the star itself is immersed. The spectrum contains strong lines of neutral helium, without any signs of emission components. The spectral class corresponds to the combined spectrum of B3–5 V  + B1.5–2 V.
