During this night, Venus, Mercury, the Sun, Jupiter, Saturn, the Moon and Mars, in that order, are all within 27° of each other (in Taurus, with Mars just in Gemini).
This is unusual enough, but around 23:45 BST (22:45 GMT, 18:45 EDT, 15:45 PDT), there is a series of conjunctions between all these heavenly bodies, with a maximum orb (allowance) of 5.5°. Given an orb of 8°, this series lasts from about 18:45 to 02:45 BST (17:45 to 01:45 GMT, 13:45 to 21:45 EDT, 10:45 to 18:45 PDT).
In addition, for around 30 minutes either side of 01:45 local sun time in Europe (and more approximately elsewhere), your Earth will also be in Taurus (see Earth in Astrology). This time is 02:45 BST for London, 03:00 BST for Cornwall, 02: 10 EDT for New York City, 02:20 PDT for San Francisco, 23:30 (4 May) Sydney Time for Sydney - here your Earth is in Taurus an hour either side of the time.
This is altogether a very powerful time, and worth staying up late for in Europe. The energy will all be concentrated in one direction, making for a very earthy time: good grounding after the Aquarius celebration last month, and very appropriate for Beltane time.
As well as the conjunctions, Uranus in Aquarius makes square aspects (90°) with Jupiter, Saturn and the Moon, and Neptune in Aquarius has squares with Venus and Mercury. Neptune also has a trine aspect (120°) with Mars, allowing us to feed into powerful psychic energy. Pluto in Sagittarius is the only planet not involved.
Below is a chart for London at 02:40 BST (01:45 GMT) on 5 May, when Uranus and Neptune are near the Ascendant. I have included close ups of the aspects and the aspect grid. It is an entirely remarkable chart, and not easy to draw because of the forest of conjunctions (blue) and squares (purple). Conjunctions intensify the planets' energy in combination with others', and squares represent energy pulling across each other. It is an earthy, sexy, maverick chart of great power.
