What is a partial lunar eclipse? How does it occur?
The moon is not round, but is egg-shaped with the large end pointed towards Earth. However, since the Sun's diameter appears about one-quarter of Earth's in the lunar sky , the planet only partially blocks direct sunlight within the penumbra, the outer portion of the shadow. A penumbral lunar eclipse occurs when the Moon passes through Earth's penumbra.
The penumbra causes a subtle dimming of the lunar surface. A special type of penumbral eclipse is a total penumbral lunar eclipse , during which the Moon lies exclusively within Earth's penumbra. Total penumbral eclipses are rare, and when these occur, the portion of the Moon closest to the umbra may appear slightly darker than the rest of the lunar disk. A partial lunar eclipse occurs when only a portion of the Moon enters Earth's umbra, while a total lunar eclipse occurs when the entire Moon enters the planet's umbra. The Moon's average orbital speed is about 1.
Nevertheless, the total time between the first and the last contacts of the Moon's limb with Earth's shadow is much longer and could last up to four hours.biacofhelpnews.tk

The relative distance of the Moon from Earth at the time of an eclipse can affect the eclipse's duration. In particular, when the Moon is near apogee , the farthest point from Earth in its orbit , its orbital speed is the slowest.
The diameter of Earth's umbra does not decrease appreciably within the changes in the Moon's orbital distance. Thus, the concurrence of a totally eclipsed Moon near apogee will lengthen the duration of totality. A central lunar eclipse is a total lunar eclipse during which the Moon passes through the centre of Earth's shadow, contacting the antisolar point. This type of lunar eclipse is relatively rare. A selenelion or selenehelion occurs when both the Sun and an eclipsed Moon can be observed at the same time. This can occur only just before sunset or just after sunrise , when both bodies will appear just above the horizon at nearly opposite points in the sky.
This arrangement has led to the phenomenon being also called a horizontal eclipse. Typically, a number of high ridges undergoing sunrise or sunset can view it. Although the Moon is in Earth's umbra, both the Sun and an eclipsed Moon can be simultaneously seen because atmospheric refraction causes each body to appear higher in the sky than their true geometric positions. The timing of total lunar eclipses are determined by its contacts: .
There is often confusion between a solar eclipse and a lunar eclipse. While both involve interactions between the Sun, Earth, and the Moon, they are very different in their interactions.
How The July 12222 Full Moon & Lunar Eclipse Will Affect You, Based On Your Zodiac Sign
The Moon does not completely darken as it passes through the umbra because of the refraction of sunlight by Earth's atmosphere into the shadow cone; if Earth had no atmosphere, the Moon would be completely dark during the eclipse. Shorter wavelengths are more likely to be scattered by the air molecules and small particles ; thus, the longer wavelengths predominate by the time the light rays have penetrated the atmosphere. Human vision perceives this resulting light as red.
This is the same effect that causes sunsets and sunrises to turn the sky a reddish color. An alternative way of conceiving this scenario is to realize that, as viewed from the Moon, the Sun would appear to be setting or rising behind Earth. The amount of refracted light depends on the amount of dust or clouds in the atmosphere; this also controls how much light is scattered. In general, the dustier the atmosphere, the more that other wavelengths of light will be removed compared to red light , leaving the resulting light a deeper red color.
This causes the resulting coppery-red hue of the Moon to vary from one eclipse to the next. Volcanoes are notable for expelling large quantities of dust into the atmosphere, and a large eruption shortly before an eclipse can have a large effect on the resulting color. Several cultures have myths related to lunar eclipses or allude to the lunar eclipse as being a good or bad omen.
The Egyptians saw the eclipse as a sow swallowing the Moon for a short time; other cultures view the eclipse as the Moon being swallowed by other animals, such as a jaguar in Mayan tradition, or a three legged toad in China. Some societies thought it was a demon swallowing the Moon, and that they could chase it away by throwing stones and curses at it.
Similarly to the Mayans, the Incans believed that lunar eclipses occurred when a jaguar would eat the Moon, which is why a blood moon looks red.
