In my article (A. A. Nikitin, “On a possible estimate of the temperatures of hot stars from the character of the emission spectrum of N III”), published in DAN, vol. 132, no. 1, 1960, on p. 89, line 27, in the expression for (\alpha_v(2s^2 2p^2P — 2s2kd^2D^2S)), the numerical coefficient should be increased by approximately a factor of 2.6. This correction does not change the results of the article, since all the calculations are of an estimating character.
