The phenomenon, which scientists call a perigee moon, occurs when the moon is near the horizon and appears larger and brighter than other full moons. The Associated Press Aug. 12, 2014 Comments People around the world this weekend looked up at the sky to view a lunar phenomenon: the supermoon. Known to scientists as a perigee moon, Earth’s neighbor appears at its largest and brightest compared to other full moons when it orbits closer to our planet. It can even be seen during the daytime. A supermoon will happen three times this year, with Sunday night’s sky show the second. The first one occurred on July 12 and the third will take place on Sept. 9.
