In my article (A. A. Nikitin, “On One Possible Estimate of the Temperature of Hot Stars from the Character of the Emission Spectrum N III”), published in DAN, vol. 132, no. 1, 1960, on p. 89, line 27, in the expression for $\alpha_{\nu}(2s^{2}2p^{2}P-2s2kd^{2}D^{2}S)$ the numerical coefficient should be increased by approximately a factor of 2.6. This correction does not alter the results of the article, since all the calculations are of an estimative character.
