The entry of the Sun into Libra (yesterday) was generally considered the most important of the four Cardinal ingresses in the year. How useful ingress charts are is a moot point, having been roundly dismissed by astrologers who studied them in depth across a range of events.
But for what it’s worth, set for London, UK, this Libra Ingress chart does have Uranus conjunct the midheaven. The 10th house covers Royalty and the government with Uranus suggesting change or at least tensions breaking out. Uranus is in a Fixed Grand Cross opposition Venus square Node opposition Mars – so a mix of excessively stubborn and disruptive. With a downbeat Sun Mercury square Saturn; and an over-hopeful Jupiter trine Neptune sextile Pluto with delusional Neptune in the 8th house of international and business finances.
The previous late June 2018 Cancer Ingress for London has the head-in-the-clouds Jupiter Neptune even more strongly emphasised, all funneled through a controlling and uncompromising Pluto in the grandstanding 5th; with Neptune in the 7th, suggesting lack of commitment to co-operative ventures and much miscommunication between partners.
The upcoming late December 2018 Capricorn Ingress also has Neptune in the 7th even more afflicted on the point of a T Square so more evasion, slipping and sliding.
The Aries Ingress 2019 a few days before the March 29 cut-off Brexit date is brutal with an Earth Grand Trine of Saturn Pluto trine a 7th house Mars in Taurus trine a wobbly Virgo Moon in the 11th house of future plans. Not much of a hint of a friendly hand-shake out of that.
I’m rather glad the astrological research specialists have deemed them uninformative. But interesting to see how they fit.
I believe cardinal ingresses were important in traditional astrology though my limited experience of reading charts suggests that outer planet ingresses into signs are much more important decider trends historically. I have recently looked at all the ingress charts leading up to the Saturn Pluto synod in 2020 but to be honest I cant really make head nor tail of them and the rules surrounding how long the effect of an ingress chart lasts seem a bit arcane. The March 2019 Ingress does have a lot of resonances in the various historic UK and English charts. For example the Ingress Mars is Conjunct Venus in Taurus Square Neptune and the Moon in Leo in the 1927 Chart. It squares the Saturn in Leo in the UK 1801 chart and conjuncts the Sun, Mercury and Mars in the England 973 Chart.
Yes, I agree these are pretty vague, but a planet on axis could be telling.
