PREDICTION OF THE GRAZING OCCULTATION

    The computer list is lunar graze predictions during the year.   
These predictions are calculated on the basis of ILOC (Japanese Ephemeris published by 
the Hydrographic Department of Japan).  
"DELTA SIGMA" means the distance between the star and mean datum of the moon at the moment 
of the close st approach.   The meaning of each column is as follows;


Explanation of the table A

 1. TIME         :   Universal time (UT)

 2. LONGITUDE    :   E : east    W : west
    LATITUDE     :   N : north   S : south

 3. SUN AL       :   Altitude of the sun

 4. ST AL        :   Altitude of the star 

 5. ST AZ        :   Azimuth of the star (measured eastward from the north)

 6. CA           :   Cusp angle
                     The angle measured from the cusp point of the moon to the grazing point
                     positive : dark limb; negative : bright limb 

 7. SNLT         :   Sunlit %, positive : waxing; negative : waning

 8. PA           :   Position angle

 9. L, B, C,     :   Librations of the moon and position angle of the north pole of the moon

10. WA           :   Watts angle, WA = PA - C + 0��.22


Explanation of the table B

 1. SEQ          :   Sequential number in the year.   The same number is attached to the
                     corresponding track on the map

 2. H-92 NO      :   The Japanese Ephmeris Star Catalog number of the star ( same as the XZ
                     Catalog NO of USNO )

 3. SAO NO       :   The Smithsonian Astrophysical Observatory Star Catalog number of the
                     star

 4. ZC NO        :   The Zodiacal Catalog number of the star

 5. MON, DAY,    :   month, day, hour, minute and second in UT for the west end of the area
                     H, M, S,

 6. SNLT         :   Percent of the Moon sunlit

 7. LIMIT        :   Whether the track is the north (N) or the south (S) limit of the
                     occultation
