Most of the previously published results of the zenith sky twilight brightness, obtained by different investigators, are given in different units. These results have been converted to (mag/arcsec) to make a comparison between them. The variation of the colour indices (B-V) and (B-R) of the zenith sky twilight with the sun’s depression will be studied. The present photometric results of the zenith sky twilight brightness expressed in mag/arcsec, have been obtained for the first time for blue, yellow and red colours.
