Ever wanted to know what a Partial Solar Eclipse is? Really need it for a school project? Well you have come to the right place, my friend. This powerpoint will give you all the information you need to know about a Partial Solar Eclipse, an eclipse that occurs rarely.

ECLIPSE

position, theonly partly during a partial solar eclipse, as seen
from Earth. This phenomenon is visible when only the
lunar penumbra (the partially shaded outer region of the
Moon’s shadow) touches the Earth. The extent of the
eclipse varies depending on the observer’s location but
regardless of a viewer’s position, the Sun is only partially
eclipsed.

3. Partial Solar Eclipses Explained
• Partial solar eclipses can be seen more often than total
solar eclipses because the Moon’s distance from the
Earth is irrelevant (not connected with or relevant to
something) and the area in which a partial solar eclipse
can be viewed is much larger.A partly obscured Sun can
be seen from Earth during New Moon, when:

4. Partial Solar Eclipses Explained (Continued)
• The Sun is near the one of the nodes of the Lunar orbit
(orbit of an object around the Moon), so Earth, Sun, and
Moon, roughly form a straight line.
• The observer is located in the Moon’s penumbra (a partial
shadow, as seen in an eclipse).

5. Why Do Partial Solar Eclipses Do Not Happen
Every New Moon?
•
The reason why partial solar eclipses happen do not happen every
New Moon is that the lunar orbital plane- the imaginary flat surface
whose outer rim is formed by the Moon’s path around Earth-runs at
an angle of approx. 5 degrees to the Earth’s orbital plane around the
Sun (ecliptic). The point where the 2 orbital planes meet are called
lunar nodes. Only if the Sun appears near one of the two lunar nodes
during New Moon
so Earth, Moon, and Sun form a straight line so a total or a partial solar
eclipse because depends if the Moon, Earth, and Sun don’t form an
exact straight line.

6. What is the difference between a solar
eclipse and a lunar eclipse?
•
A lunar eclipse is an eclipse of the Moon rather than the Sun. It
happens when the Moon passes through Earth's shadow. This is
only possible when the Moon is in the Full Moon phase. If the Moon's
inner or umbral shadow sweeps across Earth's surface, then a total
eclipse of the Sun is seen. The track of the Moon's umbral shadow
across Earth is called the Path of Totality. It is typically 10,000 miles
long but only about 100 miles wide. It covers less than 1% of Earth's
entire surface area. In order to see the Sun become completely
eclipsed by the Moon, you must be somewhere inside the narrow
path of totality. Just one total eclipse occurs each year or two.

7. How To Protect Your Eyes When Viewing Solar
Eclipses
•
If you are lucky enough to be able to see a partial or solar eclipse,
you should make sure you protect your eyes and never look directly
at the Sun without proper protection. This is because the Sun’s
photosphere emits intense UV radiation. Just as UV radiation causes
sunburn to skin, it can also damage the retinas in the eyes, but much
more quickly than sunburn.
•
The only way to view the uneclipsed or partially eclipsed Sun safely
is to either project or filter the solar photosphere’s rays .

8. How To Protect Your Eyes When Viewing Solar
Eclipses (Continued)
•
One safe way to view the Sun is to project it’s image on to a screen,
like normal white paper or cardboard. Projection works well with or
without a telescope or binoculars. However, you must never look
through the telescope’s eyepiece or side-mouthed finder scope when
aiming a telescope or binocular at the Sun to project a magnified
Sun’s image on a screen of white paper or cardboard.

9. DID YOU
KNOW?
• That this year there will be 2 solar eclipses. The first one
is on May 10 which is an Annular Solar Eclipse and the
second one is on November 03 which is a Hybrid Solar
Eclipse. If you get the chance, then for sure watch these
solar eclipses 6J!!!!!
