A partial eclipse occurs when the Moon covers only a part of the Sun as seen from Earth. This phenomenon happens during a solar eclipse when the alignment of the Sun, Moon, and Earth is not perfectly straight. As a result, observers in certain locations see a portion of the Sun obscured, creating a crescent shape. During a partial eclipse, the brightness of the Sun decreases, but it does not completely disappear. It is important to use proper eye protection, such as eclipse glasses, to safely view the event. Partial eclipses can be exciting to witness, as they offer a unique perspective on the celestial mechanics at play.
