The total solar eclipse during the 2026 Perseid meteor shower’s peak has a listed magnitude of 1.0386.
Eclipse magnitude expresses the fraction of the Sun’s diameter covered by the Moon at greatest eclipse. A value above 1 indicates that the Moon’s apparent diameter is larger than the Sun’s at that point, allowing totality along a narrow path.
Magnitude is different from the percentage of the Sun’s area covered. It is a diameter-based measure, so it should not be read as a direct percentage of solar area obscured.
The Moon was near perigee shortly before the eclipse, which increased its apparent size. That geometry helped make totality possible while the event crossed the Arctic, Greenland, Iceland, and parts of southwestern Europe.
