Abstract The photoelectric brightness profiles inU, B, andV colors of the globular cluster NGC 362 are reported down to about 9 magnitudes below the central value, covering a radial distance of about 10 arc min. They were derived fromE-W scans, with a large rectangular diaphragm, giving the integrated profile of the cluster in about 6 min. of time. The inverse problem of determining the brightness profiles from integrated luminosities is solved by means of the regularization method. The agreement with the data available in literature (photoelectric brightness measurements in the inner 80 arc sec, bright stars distribution in the range 80-330 arc sec) is generally good. TheB-V andU-B radial color distributions are presented. It may seem that there is no color gradient, outside the central region dominated by red giants.
