Scientific paper

It is shown that the systematic difference existing between the lunar motion theories in a seven-year interval reaches 0.63 arcsec for right ascension. Periodic dependences of the differences delta(j = 2) - delta(LE200) on the mean argument of the lunar altitude F = g + omega and on the mean solar anomaly are found. It is concluded that the Brown-Eckert (j = 2) and LE200 lunar motion theories possess significant systematic and periodic differences for the coordinates alpha and delta.
