magnitude of an eclipseの例文
- The magnitude of an eclipse is the ratio of the apparent size of the Moon to the apparent size of the Sun during an eclipse.
- A hybrid eclipse occurs when the magnitude of an eclipse changes during the event from less to greater than one, so the eclipse appears to be total at some locations on Earth and annular at other locations.
- This measure should not be confused with the obscuration of the eclipse, which is the area fraction of the eclipsed body occulted by the eclipsing body, whereas the magnitude of an eclipse is strictly a ratio of diameters.
