TEXT: The authors analyze the.possibility of approximating the shape of
the Moon by means of the smooth4ng curve of the following form:
r = Ro + acos (p + V~ 0
(a = 0 for -900 < P .+ I ,_, go ) -
Thus the lunar shape 4is represented b~ a semicircle of radius Ro and a 4-order
curve, r.= Ro = acos (P + r ). The mass center of the Moon coincides with- the
circle center; p is position angle of a point At the lunar edge,- r is the angle
between the projection of the polar axis and the symmetry axis of the proposed
model. The coordinate system is used which has the origin in the center of this
circle, X-axis oriented northwards, and Y-axis oriented eastwards; using this
system, the radius of the most probable circle and coordinates of its center, as

well as the value of parameter a, were calculated by the least-square method.
Materials of many years of observations of libration effect in radius and lati-
tude correcti ons, separately for the western and eastern limbs, were used. The
calculated results for values -r = 10, 15 and 200 are presented, which show agree-
ment with observations. There are 12 references.

TEXT: As it'is known, amplitudes of all waves of Moon's physical libra-
tion depend on the'adopted value of libration parameter f. To determine it, the
author proposes to calculate, using harmonic analysis method, the amplitude of the
libration-wavi.:which has mean-Sunts anomaly as argument and one-year period..
Long ext6nsioxi of observations represents a necessary condition for the possibil-
ity of separating individual periodical terms; therefore, this analysis cin be
successful only in the case when different isolated observation-series, following
each other, will be considered as one.continuous series, -The author processes

ABSTRACT: Existing metho& for detennhiing the parameters of lunar physical libration
are ineffective. The author has developed a method based solely on measurement of the
position angles of several small lunar cra;ers relative to Moesting A. The )bservationr,
