angle to the backsight. (The azimuth to
this point will be computed at the end of
the routine.)
Note: The hours to GMT will be between +5
and +8 when in the continental United States.

aim ahead of the path of the sun so that the trailing edge has not
yet contacted the vertical crosshair in the scope and tap
Take Shot to record the current horizontal angle.
11. Watch the movement of the sun in the scope. As soon as
the trailing edge of the sun contacts the vertical
crosshair, either tap the Get Local Time button or use an
external timepiece and note the precise time. (When
using an external timepiece, manually key in the noted
time in the HH, MM, SS, sss fields.)

screen and the computed
azimuth for each shot taken is displayed
with other shot information.

taken by selecting it and tapping the Del
button. This is useful if the last shot was in
error.
