In striking contrast to the vague shadings sometimes reported by visual observers are the prominent markings clearly seen on ultraviolet photographs of Venus. They were discovered at Mount Wilson Observatory by Frank Ross, a pioneer in the photography of the planets through monochromatic filters who also is photo editor for the Planetary Week. During a favorable eastern elongation of Venus in June and July of 1927, he obtained a series of photographs of the planet through the 60-inch and 100-inch reflectors in six regions of the visible spectrum and in infrared and ultraviolet light.
