Abstract: Observations of wave-optics effects in sunlight are reported. In particular, conditions are described that allow for visual detection of diffraction phenomena from line edges. Typical fringe patterns are demonstrated, also showing color features that account for the wavelength dependence of the diffraction process. Hints to optimize the observation are given, outlining the aspects of simplicity and naturalness of the occurrence.
