Can you see lunar eclipse
The first thing to remember about observing an eclipse is safety. A solar eclipse is potentially dangerous, however, because viewing a solar eclipse involves looking at the Sun, which can damage your eyesight. A solar eclipse can be viewed safely with the naked eye only during the few brief seconds or minutes of a total solar eclipse , when the Sun itself is completely obscured by the Moon. Partial eclipses , annular eclipses , and the partial phases of total solar eclipses are never safe to watch without taking special precautions.

Lunar Eclipse 2020: Where can you see the Penumbral Eclipse? What times will Moon eclipse?
While not as spectacular as a solar eclipse , a lunar eclipse can still be a beautiful and amazing spectacle. It's also a lot easier to see a total lunar eclipse than its solar equivalent! A lunar eclipse always occurs at night, during a Full Moon ; you should be able to see the eclipse if it occurs during your nighttime, and you have a view of the Moon.
But what you will see depends on the specific type of the eclipse. By the way, since a lunar eclipse occurs at night, when the Sun isn't around, it's always safe to look at a lunar eclipse. As described in Mechanics of Lunar Eclipses , the Earth's shadow during a lunar eclipse has two parts: the penumbra , where the Sun's light is only partly blocked from the Moon; and the umbra , where the Earth totally blocks the Sun's light. If the Moon touches the penumbra, a penumbral eclipse will be seen although, in practice, this type of eclipse is subtle; most penumbral eclipses can't bee seen with the naked eye ; if the Moon touches the umbra, a partial umbral eclipse will be seen; and if the Moon completely enters the umbra, the result is a total umbral eclipse , or total lunar eclipse.
A total eclipse is always preceded and followed by a partial eclipse; which is in turn preceded and followed by a penumbral eclipse. Hence, we say that a total eclipse goes through a penumbral stage, then a partial stage, then the total stage, then partial, then penumbral, before finishing. The penumbral stage of a lunar eclipse or a lunar eclipse that is only penumbral is essentially impossible to see, unless the Moon is deeply inside the penumbral shadow; even then, all parts of the Moon are still receiving light from the Sun, and therefore quite bright.
Still, in a deep penumbral eclipse, sharp-eyed observers should see a subtle but distinct shading across the Moon at maximum eclipse. This should be fairly obvious in a total penumbral eclipse. A partial eclipse, or the partial stage of a total eclipse, is heralded by the Earth's shadow beginning to take a bite out of one side of the Moon.
The remainder of the Moon will still be quite bright, as normal; but the Earth's shadow will gradually move across the face of the Moon, and the light level will drop noticeably. When the Earth's umbral shadow completely covers the Moon, the drama begins! The Moon darkens, but rather than vanishing totally, it turns a dark red or coppery-red colour. This is an amazing sight, and is caused by the refraction of sunlight through the Earth's atmosphere; although the Sun is totally blocked from the Moon, this scattered light, filtered by the atmosphere, ensures that a total lunar eclipse is a sight worth seeing.
This amazing image, by Michele Whitlow, illustrates the stages of the total lunar eclipse of 8 Oct, , from the beginning of the partial eclipse, through the total eclipse, to the end:. Depending on the prevailing condition of the Earth's atmosphere, in terms of cloud cover and dust from volcanic eruptions, the actual colour of the Moon at totality can vary from near black particularly at mid-totality , rust, brick red, and bright copper-red or orange. You can prove this by taking a picture of the Moon near the horizon, and another when it's high in the sky; with the same lens settings, the two Moon pictures will be the same size.
This effect is known as the Moon Illusion. A lunar eclipse is much easier to see than a solar eclipse. The type of eclipse you will see doesn't depend on where on Earth you are; as long as you can see the Moon, you will see the same view of what's happening to it at any given moment as everyone else. Your ability to see the Moon, of course, is governed by the Earth's rotation; as the Earth spins, the Moon, as seen from any given point, appears to rise in the East, move across the sky, and set in the West.
Since a lunar eclipse can last for hours, you may find that from your location, the Moon rises or sets part way through, and you only see part of the eclipse; or you may see it all, or none of it. As an illustration of this, the following map shows the total area of the Earth which witnessed the total lunar eclipse on July 16, :. The orange and yellow shaded areas on the map will see only the beginning of the total eclipse, as the Moon sets in the West; the cyan and blue shaded areas will see just the end, as the Moon rises; and the light area covering Australia and east Asia in this case will see the entire spectacle.
The green tag in the centre shows where the Moon was directly overhead at the moment of maximum eclipse. Bear in mind that if you're very near the edge of the area of visibility, the Moon will be low on the horizon; depending on your view of the horizon, you might not actually be able to see it.
The other good news is that a lunar eclipse, even a total eclipse, generally goes at a pretty relaxed pace the total phase often lasts an hour or more ; with that, and the lack of any need for eye protection, there's plenty of time to enjoy the view, take pictures, and have a good time! The Moon is no brighter during a lunar eclipse than at any other time, and nowhere near bright enough to cause blindness.

When Is the Next Eclipse? | Solar and Lunar Eclipse Dates
A partial lunar eclipse could be visible from the UK on Tuesday 16 July. An eclipse of the Moon occurs when the Earth lies directly between the Sun and the Moon and the Moon lies in the shadow of the Earth. For a total lunar eclipse to happen, all three are in a straight line. This means that the Moon passes through the darkest part of the Earth's shadow.

What is a penumbral lunar eclipse and is it safe to look directly at it?
But what exactly is a penumbral lunar eclipse and is it safe to look at? Here's all you need to know. In a penumbral lunar eclipse only the outer shadow of the Earth, which is called the penumbra, falls on the earth's face. It's not the most obvious eclipse as it's quite hard to spot, unlike a total eclipse which can turn the entire moon red.
The moonlight we see on Earth is sunlight reflected off the Moon's grayish-white surface. The amount of Moon we see changes over the month — lunar phases — because the Moon orbits Earth and Earth orbits the Sun. Everything is moving. During a lunar eclipse , Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. Earth's shadow covers all or part of the lunar surface. What is the Current Phase of the Moon?

Now, exactly two weeks after that cosmic event, some people can enjoy a Wolf Moon lunar eclipse coinciding with a Full Moon. Weather permitting, observers in these areas will witness a surreal Full Moon on Friday, January A lunar eclipse can only occur during a Full Moon, when the Sun, Earth and Moon line-up, with our planet in the middle. A penumbral lunar eclipse sees only the more diffused outer shadow of Earth — known as the penumbra — appear on the surface of the Moon. Eclipse expert Fred Espenak told Earthsky.
Our Guide to this Friday’s Penumbral Lunar Eclipse
Full moon will be plunged a deep red — 50 years to the day since astronauts set off to explore it for the first time. Event comes 50 years to the day after humanity set out for the lunar surface. As soon as the moon rises from behind the horizon, it will be darker and redder than usual.
Lunar eclipses occur when Earth's shadow blocks the sun's light, which otherwise reflects off the moon. There are three types — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth's shadow completely covers the moon. The next lunar eclipse will be a penumbral lunar eclipse on June 5, and will be visible from Europe, Africa, Asia and Australia.
Find out what a lunar eclipse is and when the next total lunar eclipse in the UK will occur, as well as expert tips on how to see it from astronomers at the Royal Observatory Greenwich. An eclipse of the Moon occurs when the Earth lies directly between the Sun and the Moon and the Moon lies in the shadow of the Earth. For a total lunar eclipse to happen, all three bodies lie in a straight line. During a total lunar eclipse, the Moon usually turns a deep, dark red because it is illuminated by light that has passed through the Earth's atmosphere and has been bent back towards the Moon by refraction. During the partial phase of the eclipse, part of the Moon travels through the Earth's full 'umbral' shadow.
