    Study Notes

    Solar Eclipse Observation

    • A total solar eclipse occurs when the moon is positioned directly between the sun and Earth.
    • From a point on Earth where the moon is directly between the sun and Earth, a total solar eclipse will be visible.
    • From a point on Earth where the moon is not directly between the sun and Earth, a total solar eclipse will not be visible.
    • If the moon is not directly between the sun and Earth, but is positioned in a way that blocks part of the sun, a partial solar eclipse will occur.
    • It's important to never look directly at the sun during an eclipse without proper eye protection.

    ### Solar Eclipse Explanation

    • In a solar eclipse, the moon passes between the sun and Earth.
    • Different parts of the Earth will experience different types of eclipses depending on their position relative to the moon and sun.
    • During a partial eclipse, part of the sun is visible while the moon blocks another portion.
    • During a total eclipse, the entire sun is blocked by the moon.

    Fully covered, partially covered: Total eclipse, partial eclipse

    • A line drawn from a point on Earth to the moon can depict which parts of the sun are visible or blocked.
    • If the line from Earth touches the moon in a way that blocks the entire sun, a total solar eclipse is visible.
    • If the line from Earth touches the moon in a way that only blocks part of the sun, a partial solar eclipse is visible.
    • People who are on Earth where the sun is fully blocked experience a total eclipse.
    • People who are on Earth where a portion of the sun remains visible, but some of the sun's rays are blocked, experience a partial eclipse.
    • The extent of the eclipse determines the experience, with a total eclipse representing a complete blockage and a partial eclipse blocking only a portion of the sun.

    ### Figure 1

    • A line drawn from a point on Earth to the moon shows which parts of the sun are visible or blocked.
    • The moon being slightly off-center results in different portions of the sun being covered.
    • The side of the line where the sun's rays are blocked indicates a partial eclipse.
    • The side of the line where the sun's rays are not blocked, indicates a visible sun.
    • The diagram shows the sun's rays as arrows.
