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.
