King tide occurring, predictable events. Tides are the movement of water across Earth's surface caused by the combined effects of the gravitational forces exerted by the Moon, Sun, and the rotation of Earth which manifest in the local rise and fall of sea levels. Tides are driven by the relative positions of the Earth, Sun, Moon, land formations, and relative location on Earth. In the lunar month, the highest tides occur roughly every 14 days, at the new and full moons, when the gravitational pull of the Moon and the Sun are in alignment. These highest tides in the lunar cycle are
Partial eclipses on the Moon Partial eclipses on the Moon Partial solar eclipses on the Moon are caused when the Earth passes nearly in front of the Sun, blocking a part of its light. Viewers on Earth will see a penumbral lunar eclipse. During its eclipses, the Earth will be in new phase, completely dark, except for moonshine and sunlight refracted through the earth's atmosphere, visible as a ring of light. Unlike the Earth's which shows slightly darker shadows at 50% obscuration and mostly dark at over 75% obscuration, the Moon's penumbral shadow on the surface shows light yellow at the start and the end
