The relative intensity of two CI lines at 1993.6 โ€ข and 1657.4 A, observed in the limb spectrum of the sun, is a factor 2.6 โ€ข 10 a larger than that expected if both lines were optically thin. It is shown that the observed intensity ratio may be explained in terms of the transfer of photons from 2 165
