One of the central interests of Astro-Meteorology, and probably the oldest field of astrological interest, is which planetary configurations favour rain. The first level is knowing which planets are wet and which dry. The next level is how they interact with one another. The fluctuation between temperature and moisture and their planetary connection was noted by Johannes Kepler, though he was by far not the first, nor the last to discuss this. (We speak nowadays mostly of the interaction of cold and warm fronts, although usually no planetary connection is taken into consideration.) The third level is of course how planetary configurations effect local conditions. This is important as any single planetary configuration applies to all of the earth. Methods of localization need to be taken into consideration here.
Of the traditional planets, along with the Moon, Venus is considered to be the wettest. Saturn also plays a role because of his crystallizing tendencies. He causes moisture to condense. In modern Astro-Meteorology Neptune is also considered to be a very ‘wet’ planet, though interestingly enough after his discovery Astro-Meteorologists first explored the possibility of his being warm, dry and stormy. They did however add that such “…predictions must be to some extent speculative.” (Alfred Pearce’s discussion of Neptune around 1863). More recently George McCormack wrote of Neptune being, “the most pluvial of all the celestial bodies.”
There are of course many configurations between wet and dry planets. Let us choose one. Venus in configuration with either Mars or the Sun. I’ll note it as:
Venus : Mars/Sun,
where the configuration, “:” can be an aspect by longitude or declination.
Take a peek into your ephemeris and look for the next significant configuration between Venus to either Mars or the Sun. You will find it on the 13th of October, 2009. Venus sextiles Mars on this day, and not only that she has just previously, in the same degree, also conjuncted Saturn. This is an intensive conjunction as she is also at the same declination of Saturn and is therefore parallel. Let us note it thus:
Venus : Mars + Venus :: Saturn
we can expect this aspect to be very pluvial. But that doesn’t mean everywhere. There we need to place it into the locality. This is best done by casting a chart for the location when this aspect is exact. From my previous discussion on expecting more from aspects we may also take the standpoint that the effectiveness of this aspect is not only on the day it takes place but already begins one to two days before (application) and will last for two days afterwards (separation). So we are looking at the period from the 11th of October to the 15th.
I will be looking at three charts for my location. These are the previous lunar phase (Last Quarter on the 11th of October), the partile Venus/Mars sextile and the preceding partile Venus/Saturn conjunction and parallel within 29 seconds of arc. You might want to cast these three charts for your location (I am using GMT so you can take the GMT time for your location) and then observe what the weather conditions were in this period. It would certainly be very interesting if these observations were to be posted as a comment here when the time comes.
Last Quarter Moon:
Important for location are the 4th house and Ascendant, respectively. The Moon/Sun square is not predominant in this chart. The Lords of both the 4th and 1st house are also not prominently placed. Uranus is in the 4th house and Venus, Saturn and Mercury occupy the 10th house, with Venus and Saturn being in the same sign as the MC and Mercury in the following sign.
In this chart the 4th house is immediately brought into focus by the trine of the Moon at 17 Leo 37. Also Lord 4 is Mars, who is already in sextile to the Venus/Saturn conjunction. Jupiter, Lord 1 is also exactly in sextile with the IC. So we can definitely speak of an activation of the locality.
Here the Mars/IC conjunction is immediately noticed. This particular aspect is focused on the locality, that is for sure!
Now what does it all mean? The Venus : Mars configuration occurs when Mars is focused on a locality with a cold and moist sign on the IC. So cold rainy and slightly stormy weather should be expected.
I’ll keep you posted around the 15th of October and then we can look at the charts with hindsight!
