Annular eclipses How to view a solar eclipse.There are 3 main types of solar eclipses: On average, 2 to 4 solar eclipses in the same calendar year are known to occur. Essentially, several factors need to happen simultaneously for an eclipse to happen making it a rare natural event. This means that the illuminated portion of the moon is facing away from the earth. A partial solar eclipse can be viewed from these regions.Ī solar eclipse occurs only when the moon is in the new moon phase. In areas where the moon partially covers the sun, a lighter shadow is projected on the earth's surface which is called the penumbra. The sun appears as a ring around a dark moon when viewed from within the antumbra (annular eclipse). The shadow formed by such an eclipse extends beyond the umbra and is called the antumbra. When the moon is further away from the earth, it appears small and does not cover the sun's disk completely. A total eclipse occurs in the places this dark shadow, also called the zone of totality, happens to fall. One is the umbra, which is the dark shadow formed when the moon completely blocks the sun's light. The shadow of the moon during an eclipse has three parts.
What is meant by umbra, penumbra and antumbra? If it is a partial solar eclipse, there may be a twilight-like appearance during the day, and daylight returns once the phase of the eclipse is over. The day plunges into total darkness just like a night in these regions in the case of a total solar eclipse. This causes the shadow of the moon to fall on some parts of the earth's surface.
