Moon occurs when the Moon makes no more major aspects before it leaves a sign. VOC Moon is used in horary astrology, which tracks the Moon as it moves through a sign. Horary notes the major aspect of the Moon just preceding the question, then each succeeding major aspect of the Moon until the Moon leaves the sign. The aspects following the question tend to show the course of how the question will work out, probabilities. VOC Moon and aspects of the moon are also used in daily activities planning.
Corporate astrology is the chart of a corporation as an entity in itself.
If the business does not have a DBA, then the time that the business first received money or had its grand opening may be used. If you know your exact birthtime, relocation astrology is very exact and accurate. These lines have a very wide orb of several hundred miles, and as such, they are mostly useful as background information to the astrologer, even though this system has been the most widely promoted and sold to the public over years. I use this background data for myself in considering locations for my clients, but my main relocation tool is Local Space Mapping. I have found though my own research that local space lines, curved lines radiating out from the birthplace, are accurate to within 20 miles, giving great precision.
