Scene notes:

…mid-level clouds at sunrise. UAS hovering at altitude at dawn. Altocumulus Castellanus are ideal clouds for creating light rays that persist. First, their presence in the sky indicates moisture at the medium levels. As droplets glow in the sunlight, areas of thicker cloud create the shade necessary for the ‘light ray’ to show with definition. Since Castellanus clouds have these small patches of thick density, stark sunbeams are cast toward the camera’s general point of view.
