Here is an image of what Len is describing; most of the planets, anyway. To see the exact alignment, it’s necessary to read the numbers. Mars, right at the bottom of the chart in purple, next to that yellow circle with a line through it, is at 28+. The yellow guy is a hypothetical point called Transpluto. It doesn’t exist anywhere but in math, on the chart and on the astral level, and we experience it psychologically as focus, precision, a specific approach: good thing to have when Mars is around. Mars is not an energy you want to be sloppy with.
Directly on the opposite end of the wheel (in a blue glyph shaped like a trident) is Neptune at 28+ Aquarius: that the numbers match tells you the opposition is exact. Then comes the Moon, at 26+ Aquarius, about to make a conjunction to Neptune and an opposition to Mars and Transpluto. The Moon moves about one degree every two hours, so you know it’s going to be exact in about four hours from the time the chart is cast.
The shadowy looking thing to the left of the Moon is called the mean oscillating apogee, or the Black Moon Lilith. This is an aspect of the feminine, usually concealed, only whispered of, but known to all.
