The diamond-ring effect is seen during a total solar eclipse on Monday, August 21, 2017 from onboard a NASA Gulfstream III aircraft flying 25,000 feet above the Oregon coast. As the last bits of sunlight pass through the valleys on the moon's limb, and the faint corona around the sun is just becoming visible, it looks like a ring with glittering diamonds on it.
