The LmapWin Eclipse simulation software has the following main features.

1) Display of the Eclipse Map
The LmapWin calculates and draws the eclipse on the world map.
2) Display of the Local Circumstance
The LmapWin calculate the local circumstance such as maximum magnitude,
time , altitude of the moon and direction at the given place.
3) Display of the Sky at Max. Magnitude
The LmapWin display the Sky view at maximum magnitude if that point is in
the area of the total eclipse.

(The above figure is Japanese version)

The improved point of Version 2.50 from Version 2.60

1) Delta T value is revised
The delat T was revised based on L. V. Morrison(2021)
2) Fixed incorrect display of year
