Marilyn Crotty snapped this superb photo of a rainbow along the shoreline in the Conception Bay South area of the Avalon. Marilyn didn't tell me what time it was when she took the picture, but judging by the arc, I can tell it was not at sunrise or sunset. At those times, a rainbow's centre, the anti-solar point, is on the horizon; the rainbow is half in the sky and displays a large semicircle. As the sun rises, the bow's centre sinks. A rainbow is always located opposite the sun and that's why rainbows are not seen at noon.
