can be predicted with much precision using mathematical equations
which take into account the motion and size of the earth, moon,
and sun. The data presented in this set were computed by NASA
long before the solar eclipse of February 26, 1998 took place.
Mathematical models of the event enable observers to station themselves
at prime viewing locations which allow them to see a rare phenomenon
- a total solar eclipse. The data can also be used to predict
the appearance of the partial eclipse for a given observer position.
In this activity, we will download the calculated data into spreadsheets
for sorting and graphing variables which are involved in the eclipse.
