partial eclipse Celestial event during which only a part of the occulted body is blocked from view.
penumbra Portion of the shadow cast by an eclipsing object in which the eclipse is seen as partial.
partial eclipse -- an eclipse during which only the partial shadow touches the Earth (for a solar eclipse) or the Moon (for a lunar eclipse).
partial eclipse
An eclipse as seen in the penumbral shadow where the eclipsed object is not completely covered.
Partial Eclipse (lunar or Solar)
Partial eclipses are caused when the moon passes through only part of the umbra shadow of the earth. Or when the earth passes through the only part of the umbra shadow of the moon.

partial eclipse (lunar or solar): A lunar eclipse in which the moon does not completely enter Earth's shadow; a solar eclipse in which the moon does not completely cover the sun.
PARTIAL ECLIPSE
A partial eclipse happens when the moon partially blocks the sun or the shadow partially blocks our view of the moon.
A partial eclipse of the Sun occurs on January 4, but will not be seen in New Zealand. The eclipse is visible from most of Europe, except the extreme north where the Sun does not rise at this time of year.
The partial eclipse ends.
Total Lunar Eclipse : 21 February
The entire eclipse will be visible from South America, eastern half of Central and North America, Greenland, Iceland, northwestern Africa and western Europe.
In the partial eclipse path one will not be able to see the spectacular corona or nearly complete darkening of the sky, yet, depending on how much of the sun's disk is obscured, some darkening may be noticeable.
During a partial eclipse, a related effect that can be seen is anisotropy in the shadows of objects. Particularly if the partial eclipse is nearly total, the unobscured part of the sun acts as an approximate line source of light.
October 17th Partial Eclipse of the Moon
Much of the world that misses this month's solar eclipse will get to see the October 17th partial lunar eclipse.

are such that, when in line with the sun, the moon is surrounded by a ring of light, the eclipse is annular; and when the moon passes to one side of a straight line from sun to observer and shows a crescent of light, it is a partial eclipse.
In May 1993, a slight partial eclipse will be visible in the Pacific Northwest and western Canada.
it suffers partial eclipse and fades to magnitude 3.5. The duration of each eclipse is 94 hours.
This is called a solar eclipse; if the alignment is slighly imperfect then the Moon covers only part of the Sun's disk and the event is called a partial eclipse.
For example, in the path of totality (the track of the umbra on the Earth's surface) the eclipse will be total, in a band on either side of the path of totality the shadow cast by the penumbra leads to a partial eclipse, ...
When the Moon passes through the Earth's umbral shadow we can either see a Partial Eclipse, when only part of the Moon is obscured, or a Total Eclipse.
An annular eclipse is a type of partial eclipse, where only part of the Sun is covered up. During a total solar eclipse, you need to be in the path of totality to get the full, dark eclipse. Otherwise, you will only experience a partial eclipse.
Before the moon enters the umbra in either total or partial eclipse, it is within the penumbra and the surface becomes visibly darker.
From the areas outside this narrow strip, the Sun appears to be only partially covered and a partial eclipse is seen. A partial eclipse will also occur if the Sun, Moon, and Earth are not precisely lined up.

When just the Penumbra shadow touches Earth, it is a partial eclipse of the sun in that place. Only part of the sun is blocked.
Partial eclipses occur when the Sun is incompletely covered. Annular eclipses occur when the Moon it near the farthest part of its orbit and hence appears smaller. In this case a bright ring of sunlight is seen around the dark body of the Moon.
August 11 - Partial Solar Eclipse. The partial eclipse will be visible in parts of northeast Canada, Greenland, extreme northern Europe, and northern and eastern Asia. (NASA Map and Eclipse Information) ...
(i) The shadow that results when only part of the bright object is occulted; e.g. an observer will see a partial eclipse when he is in the penumbra of the shadow of the moon. (ii) The lighter area surrounding a sunspot.
while a total or annular eclipse is actually total or ring-formed in only a small band within this band (the eclipse path), and partial elsewhere (total eclipse takes place where the umbra of the Moon's shadow falls, whereas a partial eclipse is ...
Indeed the variability in the star's brightness has been tentatively attributed to its occultation (partial eclipse) by at least one orbiting planet.

This is especially dangerous during a partial eclipse only because the total light is sufficiently reduced that you could look at the sun without being overwhelmed.
A partial eclipse (when it passes through the penumbra) can last more than 2 hr, and the entire lunar eclipse may continue for as long as 4 hr.
96 days, the "star" undergoes a partial eclipse of about a tenth of a magnitude, showing that it actually consists of TWO almost identical stars in a tight orbit, ...
