2014 8 27 Is there a lunar eclipse?

Not in the lunar calendar.

Ten. 5. 16. The moon moves in the opposite direction to the sun. At this time, if the center of the Earth and the Moon are roughly in the same straight line, the Moon will enter the Earth's umbra and produce a total lunar eclipse. If only part of the Moon enters the Earth's umbra, a partial lunar eclipse occurs.

When the Moon enters the penumbra of the Earth, it should be a penumbral eclipse, but because its brightness is weakened very little and it is not easy to detect, it is not called a lunar eclipse, so there are only two kinds of lunar eclipses: total lunar eclipses and partial lunar eclipses. Lunar eclipses occur in the hope (full moon), but not every lunar eclipse occurs, which is the same as not every solar eclipse. A phenomenon in which the Moon is completely or partially obscured by the Earth's shadow.

Lunar eclipses generally occur on the sun, that is, on the fifteenth or sixteenth day of the summer calendar month, when the earth moves between the sun and the moon, but not every solar eclipse may occur, because there is an angle between the ecliptic and the white way, so only on the night of the moon, the moon and the lunar eclipse are continuous**, and the earth's shadow can be seen near the intersection of the ecliptic and the white path, and the observer on the earth can ** lunar eclipse. The number of lunar eclipses that occur each year is generally 2. The diameter of the Sun is much larger than that of the Earth, and the Earth's shadow can be divided into umbra and penumbra.

The diameter of the Earth is about 4 times that of the Moon, and in the orbit of the Moon, the diameter of the Earth's umbra is still twice that of the Moon. A partial lunar eclipse occurs when the Moon is always partially obscured by the Earth's umbra. And when the Moon enters the Earth's umbra in its entirety, a total lunar eclipse can be seen.

If the moon enters the penumbral region, the sun's light can also be obscured somewhat, this phenomenon is called a penumbral lunar eclipse in astronomical terms, but because the sunlight is still very strong in the penumbral region, in most cases the penumbral lunar eclipse is not easy to distinguish with the naked eye, but in fact the penumbral lunar eclipse is a frequent occurrence, according to the statistics of observational data, the percentage of penumbral lunar eclipses, partial lunar eclipses, and total lunar eclipses in each century is about, and.

No, August 27 is the third day of the lunar calendar, and a lunar eclipse can only occur when the moon is full.

Light travels in a straight line in the same homogeneous medium, and a lunar eclipse is a phenomenon that occurs due to the straight line propagation of light

So choose A

At 10:51 a.m. on September 28, 2015, the total lunar eclipse will not be visible in China.

This year's "supermoon" occurred around 10:51 a.m. on September 28 (Mid-Autumn Festival falls on September 27). At this time, the Moon, the Earth, and the Sun line up in a straight line and a total lunar eclipse occurs (the Moon is at its roundest), and the Moon moves to the closest point to the Earth and appears to have the largest apparent area. By now, today's total lunar eclipse has long since ended.
