The Sun enters the Sign of Aries tomorrow, on 20th March. This is the Vernal, or Spring, Equinox when day and night are of equal length (equi - equal, nox - night) and it marks the point in the year when the Sun crosses the equator and moves from the southern to the northern hemisphere. The start of Spring in the northern hemisphere marks the start of Autumn in the southern hemisphere.
I've set up the chart for the Sun's change of Sign from Pisces to Aries (also known as the zero point of the zodiac). The chart is set for 06.00 GMT in London, with the Sun just 33 seconds into Aries; at this time it will have been hovering over the zero point and entering Aries for approximately 10 minutes. If you're up and awake then you can welcome the Sun and the start of Spring!
Aries is the first Sign of the zodiac and is associated with go ahead behaviour, leadership qualities, a tendency to rush at things and reflect on them later (that "opening your mouth and putting your foot in it" syndrome!), impulsiveness, an ability to get new things started, lots of energy and enthusiasm and a fearlessness which can allow those with Sun in Aries to forge ahead where others would falter.
The symbol for Aries is the Ram. With head and business-like horns down it can rush headlong at anything which gets in its way, or which it wants to get the better of.
The chart has some interesting features. There is a Double Ambivalence figure which fills a large area of the chart. Quadrangular in shape, it has a security-seeking motivation. One part of it works energetically with that Aries Sun at the "doing" apex of the red part of this figure. At the blue "escape" corner is Saturn. These these two planets are connected on the inside of the figure by a green quincunx endowing awareness and the capacity to learn; Sun and Saturn can work cooperatively if the enthusiasm of the Aries Sun can be tempered by the caution of the Virgo Saturn. The other planets involved - Mars and Pluto - share the same Cardinal qualities as the Sun. Saturn alone in this pattern can provide a Fixed and steadying influence and will help underpin the security which this particular figure seeks.
