Just ahead of the New Moon in Sagittarius on the 20th, the Sun travels across the degree that Pluto is currently occupying. It's something that happens once a year, so that's not unusual, but this year Pluto is slowly travelling across the degree that the Galactic Centre sits, and this hasn't happened for nearly 250 years.
Pluto has a formidable reptuation for the intensity of impact in a chart, and Pluto conjunct Galactic Centre is a long-term influence because it moves so slowly. This means there's lots of time to ponder the effects, but the addition of the Sun's presence over the next few days just might shine a light of understanding onto your own personal relationship with this energy.
Kathryn Cassidy has an inspiring post on the current astrology energy, and its evolutionary potential. She says:
"Any evolutionary leap won't make news headlines. It is not something we will visibly witness. However an event in the world, or an event in your life around December 18th 2006 could be a trigger to something, which in retrospect (days, weeks, months or even years to come) we shall note signalled the beginning of major change - a new era in history."
