Time (UTC)02:43 AM UTC
Local: May 7, 1917, 2:43 AM UTC
SignScorpio
The Moon stands in opposition to the Sun, achieving maximum illumination. Classical doctrine treats the Full Moon as a peak of lunar expression - the Moon is fully lit, powerful, and separated from the Sun by the widest arc.

Time (UTC)01:48 AM UTC
Local: May 14, 1917, 1:48 AM UTC
SignAquarius
The Moon stands in its third square to the Sun, now waning and decreasing in light. Classical doctrine marks this as a moment of release, clearing, and dissolution as the cycle moves toward its end.

Time (UTC)12:47 AM UTC
Local: May 21, 1917, 12:47 AM UTC
SignTaurus
The Moon conjoins the Sun, becoming invisible and combust. Classical doctrine regards this as the weakest lunar condition - the Moon is without light, applying to the Sun, and incapable of reflecting its rays.

Time (UTC)11:33 PM UTC
Local: May 28, 1917, 11:33 PM UTC
SignVirgo
The Moon stands in square (quartile) to the Sun, having completed one quarter of its synodic cycle. Classical doctrine marks this as a moment of tension, decision, and action - the Moon's will presses against the solar principle.

Tetrabiblos
Claudius Ptolemy

"The second part of the consideration relates to each month, and requires a similar observation of the new or full Moon first taking place on the Sun’s progress through each sign: and it must be remembered, that, if a new Moon should have happened at a period nearest to the Sun’s transit over the past tropical or equinoctial point, the new Moon also in each succeeding sign, until the commencement of the next quarter, are to be observed; but, if a full Moon should have so happened, then similar observation is to be made of each subsequent full Moon. The angles, also, must be duly attended to, as well as the planets and stars ruling in both the places [104] ; and especially the nearest phases, applications, and separations of the planets, and their properties. The peculiar qualities of the two places, and the winds, liable to be excited by the planets themselves and by those parts of the signs in which they may be situated, are likewise to be considered; and also that particular wind, which is indicated by the direction of the Moon’s ecliptical latitude. By the aid of these observations, and by weighing and comparing the existing vigour of each of the several properties and qualities, the general constitution of the atmosphere during each month may be predicted"

"The third part of this consideration appertains to significations applying more minutely, and points out their force or weakness. In this case, the partile configurations of the Sun and Moon, at the intermediate quarters, as well as at the new or full Moon, are to be attentively regarded; since there is a certain variation in the constitution of the atmosphere, which usually commences about three days before, and sometimes, also, about three days after the Moon has equated her course to the Sun"

"When you shall make the minute of a ☌ your Basis or Radix, you may give judgment of the change of Weather in that moneth; for your judgment shall be framed according to the principal Dominator of the Angle of every Figure, for that Planet overcomes in the Nature of the Aire; assuming together with these things the Quality of the present time, viz. the season of the year"
