Rocketborne photometric observations in 40-nm-wide wavelength bands centered at 180, 220, and 260 nm are used to analyze the surface brightness of galactic UV light in a region extending from 220 to 260 deg galactic longitude and from -20 to +82.5 deg galactic latitude. The results are compared with simultaneous visible observations at 593 and 900 nm, with galactic light models, and with the expected contribution from stars in the field of view. It is found that: (1) the UV width of the Milky Way is tighter than in the visible and also tighter than existing models for the UV predict; (2) the brightness in the UV drops to half its peak value within only 8 deg; (3) the UV brightness is nearly constant and smoothly distributed above 25 deg latitude and up to the galactic pole; and (4) there is excess emission in the 260-nm channel which might be caused by resonance scattering of sunlight by Mg(+) ions in the upper ionosphere. Observed residuals at 180 and 220 nm are tentatively attributed to diffuse galactic starlight. Comparison with previous measurements indicates a marginally higher intensity for diffuse galactic light at high latitudes and a considerably higher ratio of diffuse to stellar light.
