Solar and Lunar Eclipses 2.0

Solar Eclipses

Total-annular solar eclipses processed by the program are comprised between 1900 and 2100 (exactly 287 eclipses from May 28th, 1900 to September 4th, 2100).

The program gives the times of the phases (initial, central and final) and the geographical coordinates where it is possible to observe those circumstances of the eclipse. It also gives maximum duration and the width of the lunar umbra.

The program has two functions: Earth Map and Movie. The first allows to see the path of the lunar umbra on Earth surface; the second creates an animation: the user will see the eclipse from one hour before up to one hour after its maximum phase. Moreover it is possible to change geographical coordinates of the observer, the starting and finish time and the time interval to see the "movie".

Partial Solar Eclipses

It is also possible to observe Solar Partial Eclipses. The program uses data of partial eclipses from 2000 up to 2019. The user can change geographical coordinates of the site.


Lunar Eclipses

The program gives information about all Lunar eclipses from 1999 up to 2030. For each eclipse we have the following data.

Type of eclipse: Partial umbral eclipse, Total umbral eclipse, Partial penumbral eclipse, Total penumbral eclipse. It should be noted that penumbral eclipses are not observable with the unaided eye, unless their magnitude is greater than about 0.7.

Date and instant of the maximum phase, the beginning and the end of the partial phases (only for umbral eclipses).

Magnitude: the eclipse is total if the magnitude is greater than 1.

Moon at zenith: longitude and latitude of the geographic place where the center of the Moon is at zenith at the time of maximum eclipse (rounded to the nearest degree).

Where the eclipse occurs: North or South of the ecliptic, near Ascending or Descending node.
It is possible to insert (and to store!) geographic coordinates to obtain information about the observability of the lunar eclipse from any sites.

Graphical representation shows umbral and penumbral area and the path of the Moon on the sky. The horizontal line is the ecliptic. Above the graphic there are the instants (from right towards left) of the beginning, the maximum and the end of the main phases.


These programs are included in "Planet 2000" program. Who buys "Planet 2000" does not have to purchase "Eclipses".
