SunFollower at LExp is an interactive web application designed to visualise the movement of the sun and the phases of sunlight for any given day and location. By displaying sunrise, sunset, sun trajectory, and shadow lengths on an easy-to-use map, it helps users plan activities that depend on sunlight, such as photography, gardening, solar panel placement, and architectural design. The tool is also popular among researchers and investigators for geolocation and chronolocation tasks, allowing precise analysis of sun position and shadow angles. SunFollower offers a practical, accessible way to understand and predict sunlight conditions anywhere in the world. It is a versatile and user-friendly tool for anyone needing detailed information about the sun's movement and sunlight phases at specific locations and times.
