 "method": "Sun position: NOAA solar algorithm, 5-minute steps. Rainbow: a primary bow forms about 40 to 42 degrees from the antisolar point; a window is kept when, from at least one OpenStreetMap viewpoint, part of the spray cloud at the foot of the falls lies at that angle with the sun up, behind the observer and above the rim of the gorge as seen from the foot of the falls (SRTM 30 m terrain model). Golden hour: sun between 0 and 6 degrees. A real rainbow also needs sunshine on the spray and enough water.",
