        -----------------

       The CANON contains all the solar eclipses (total, annular or partial ) from -2000 to 3000.
        For each eclipse one gives the precise date of the maximum together with the main characterisitics.
        The data is given in displayable and downloadable files of moderate size.
 
 

       Each  file is organized by year  as follows :
        -----------------------------------------------------

              Year    2001

      JD(TDB)      Date      Hour    Type        Lat    Long    Duration   Shadow  Speed  h_sun 
                                                  °       °        mn        km     km/s    °   
   2452082.004  21/ 6/2001  12: 4   Total      -11.2       3      5.03     167.3   0.552   55.2
   2452258.370  14/12/2001  20:52   Annular        1    -131      3.78     111.8   0.490   65.9

 
JD       :    Date of greatest eclipse in julian day TDB
Date     :    Same in dd/mm/yyyy format and in UT (Gregorian calendar since 15/10/1582)
Hour     :    Time of the maximum in hh:mm  in UT
Type     :    Total, annular or partial
 

Lat      :    Latitude of the earth location at greatest eclipse
Long     :    Longitude of the earth location at greatest eclipse( > east)
Duration :    Maximum duration in decimal mn
Shadow   :    Shadow width at greatest eclipse in km
Speed    :    Velocity of the shadow on the earth in km/s
h_sun    :    Altitude of the sun in degress
 
 

• The difference between TDB and UT is quadratically extrapolated in the distant past or in the future from known values of TD - UT.
• The difference reaches several hours in the distance past, so  JD xxxxxxx.500 is not the  beginning of a calendar day in UT.
• Computations are based on lunar and solar theories developped at the Institut de Mécanique Céleste in Paris
• The ratio k between the moon and earth radius is taken as  0.2725076 (IAU recommended value)
