The details of a study of the spectral energy distribution from 340 to 700 mµ of light from the northwestern sky at New Delhi, India, during the monsoon months of July, August, and September are given, along with a brief description of the salient features of the curves. The CIE color coordinates and the correlated color temperatures have been determined for all the curves. These and the results of earlier workers have been discussed in relation to the Abbot-Gibson curve and the E1-E2 curve of Henderson and Hodgkiss.
