The prominent Russian astrologer Pavel Globa was the first of the modern
astrologer who started talking of the Light Moon. But for years nobody
could realize what is this astrological point, with its cycle of 7 years,
and connected with the lunar orbit.

This incomprehension was a reason why the ephemerides of two different
Light Moons (Selena with its cycle of 7 years precisely and Arta with its
cycle of 6 years 11 months and 5 days) appeared in 1985-1988, at the initial
period of the Avestan School of Astrology (AShA, which was established
a few years earlier). These tables were obtained empirically or, to be
exact, by statistical analysis of the Light Moon's positions which were
placed in a few dozens of horoscopes by Pavel Globa just on a basis of
his intuition. One of the authors of the above-mentioned ephemerides (and
one of the nearest Globa's disciples until now) told me that the found
succession didn't arrange in a linear dependence (what is not amazing because
the nature of the Light Moon is too complicated; it can not be described
by a linear formula), but it was "good enough" to be arranged
in two linear dependences. Thus the consequence about existence
of two Light Moons was made. This opinion -- never declared before -- quickly
surfaced and spread in astrological circles, which are so sensitive to
any extraordinary currents; and the legend about two (or even more, in
some astrologers' minds) Light Moons ran and ran until today. Let's note
that the arising of this myth is a result of a totally wrong notion
of the Light Moon as a point which has a simple constant movement along
the ecliptic. The real Light Moon's movement is much more interesting and
complicated. It is not simpler then, for instance, the movement of the
Lunar Node or the Dark Moon (the true apogee of the lunar orbit). But it
was not taken into account at that time, and usually it is not considered
now.
