Stereographic Projection Map of the Eclipse Path
The stereographic projection of Earth in
Figure 2 depicts the path of penumbral and umbral
eclipse in greater detail. The map is oriented with the north up with the point of greatest eclipse near the
center. International political borders are shown and circles of latitude and longitude are plotted at 20°
increments. The region of penumbral or partial eclipse is identified by its northern and southern limits, curves of
eclipse begins or ends at sunrise and sunset, and curves of maximum eclipse at sunrise and sunset. Curves of
constant eclipse magnitude are plotted for 20%, 40%, 60% and 80%, as are the limits of the path of total
eclipse. Also included are curves of greatest eclipse at every half hour
Universal Time.
Figures 1 and
2 may be used to determine quickly the approximate time and magnitude of
maximum eclipse at any location within the eclipse path.
